Guiding Principles for Learning and Teaching of NumberInquiry –based learning Learning is inquiry based. Children are routinely engaged in thinking hard to solve arithmetical problems

Initial and on-going assessment Learning is informed by ongoing assessment through teaching.

Zone of Proximal Development Learning is focused just beyond the cutting edge of children’s current knowledge.

Quality crafted lessons Learning approaches are carefully selected to meet the needs of this child.

Developing more sophisticated strategies The teacher understands the children’s numerical strategies and deliberately engenders the development of more sophisticated strategies through mathematisation.

Observing and fine-tuning learning Observation of learning informs micro-adjustments within lessons

Symbolising and notating Children talk about their strategies and over time learn to notate their thinking and formalise this.

Sustained thinking and reflection Wait time is valued and given

Intrinsic Satisfaction Through distancing settings and self-checking their thinking children understand they are making progress.

Mathematisation Theme Addition and Subtraction Multiplication and Division Fractions, Decimals and Percentages

Structuring number Understanding the underlying connections between numbers (e.g. 16=10+6,8+8, etc.)

Understanding the fairness and equality of multiplication and divisionLinking and applying knowledge of addition and subtraction to multiplication and divisionUnderstand composite and unitary aspects of a quantity

Linking and applying knowledge of Multiplication and Division to Fractions, Decimals and PercentagesUnderstand composite and unitary aspects of a quantity

Extending the range of numbers Progressively introducing a wider range of numbers to calculate with

Introducing multiples and sequences in steps to ensure secure understanding

Building on knowledge of fair share and equal parts, sequentially introduce fractions in steps to ensure secure understanding. This leads to a depth of understanding within fractions and this knowledge enables learners to develop a meaningful understanding of decimals and percentages.

Decimalising towards Base-ten thinking

Developing base ten thinking that exploits using ten as a unit (e.g. conceptual place value and counting in tens)

Applying conceptual place value to multiplication and division Applying conceptual place value to Fractions, Decimals and Percentages

Unitising and not counting by ones Regarding a number larger than one as a unit and use this unit to solve a task.

National BenchmarksEstimating and rounding Recognises the number of objects in a group, without counting (subitising) and uses this information to estimate the

number of objects in other groups. Checks estimates by counting. Demonstrates skills of estimation in the contexts of number and measure using relevant vocabulary, including less

than, longer than, more than and the same.Number and number processes Explains that zero means there is none of a particular quantity and is represented by the numeral 0. Recalls the number sequence forwards within the range 0 - 30, from any given number. Recalls the number sequence backwards from 20. Identifies and recognises numbers from 0 to 20. Orders all numbers forwards and backwards within the range 0 - 20. Identifies the number before, the number after and missing numbers in a sequence within 20.

Uses one-to-one correspondence to count a given number of objects to 20. Identifies ‘how many?’ in regular dot patterns, for example, arrays, five frames, ten frames, dice and irregular dot

patterns, without having to count (subitising). Groups items recognising that the appearance of the group has no effect on the overall total (conservation of number). Uses ordinal numbers in real life contexts, for example, ‘I am third in the line’. Uses the language of before, after and in-between. Counts on and back in ones to add and subtract. Doubles numbers to a total of 10 mentally. When counting objects, understands that the number name of the last object counted is the name given to the total

number of objects in the group. Partitions quantities to 10 into two or more parts and recognises that this does not affect the total. Adds and subtracts mentally to 10. Uses appropriately the mathematical symbols +, − and =. Solves simple missing number problems.

National BenchmarksFractions, decimal fractions and percentages Splits a whole into smaller parts and explains that ‘equal parts’ are the same size. Uses appropriate vocabulary to describe each part, at least halves and quarters. Shares out a group of items equally into smaller groups.

If this is 13

, what would the whole look like?

What would 12

of the whole look like?

What can you tell me about the difference between the two unit fractions? How do you know?

● I can predict and compare the difference in size between unit fractions of the same whole. E.g.14

is larger than and 16

This is the whole. Ask child A to estimate ¼ and Child B to estimate 16

. .

Ask the children to estimate the size of their unit fraction, predict which one is the largest and justify their reasoning using the whole measure.

UNDERSTANDING ADDITION, SUBTRACTION AND DIVISION OF FRACTIONSLearning OutcomesPreparing for addition and subtraction of fractions

● I can partition a given partitioned bar in order to show a different fraction within the bar (when these share a common factor).e.g Using the 5/5 bar, can you find 1/10 Explain how you solved this.

How many 1/10 are required to make the unit fraction (1/5) - Repeat with 1/15, 1/20, 1/25 - Repeat with other fraction bars e.g to find 1/9 on a 3/3 bar, 1/12 on a 4/4 bar.

● I can partition a given partitioned bar in order to show a different fraction within the bar (when there is no common factor). e.g Here is a 2/2 bar, find 1/3 without erasing the third partitions. Can you identify at least two ways to solve this task. - Repeat with other fraction bars e.g to find 1/4 on a 3/3 bar, 1/4 on a 5/5 bar.

Adding and Subtracting Fractions I can find the common fraction to add and subtract two unit fractions. e.g. Using a 3/3 bar. Add together 1/3 and 1/12. Now subtract 1/12 from 1/3.How did you solve this using visual representation? , How can we use notation to demonstrate your thinking?What were the similarities and differences in the strategies you used to add and subtract?

Repeat with other fractions (Can be more challenging by using smaller fractions e.g. 1/6 + 1/24).Repeat without providing visual bar (children required to make own visual representation)

I can find the common fraction to add and subtract two composite fractions.e.g. Using a 3/3 bar. Add together 2/3 and 3/12. Now Subtract 3/12 from 2/3.How did you solve this using visual representation? - How can we use notation to demonstrate your thinking?What were the similarities and differences in the strategies you used to add and subtract?

Repeat with other fractions (Can be more challenging by using smaller fractions e.g. 5/6 + 9/24)Repeat without providing visual bar (children required to make own visual representation) I can add and subtract fractions which involve fractions within and beyond the wholee.g. 2/3 + 5/12, 6/5-2/3How did you solve this using visual representation? - How can we use notation to demonstrate your thinking?

I can add and/or subtract fractions to solve multi step word problems.e.g. Katy has 4/5 of a litre of petrol in her lawnmower. She buys ¼ litre more. Then she uses 3/8 of a litre. How much of a litre does she have now?e.g. David has 10 metres of wood to make a table. He uses 4/7 of this to make the tabletop and 3/8 to make the legs. How much wood does David have left?

Dividing Fractions

I can distinguish between two meanings of division- measurement meaning and sharing meaning.e.g. ask children the children to make a visual representation to show the difference between these two division tasks:The ribbon is 39 cm long. A single serving is 3cm/ How many people can get a serving? (measurement meaning)The ribbon is 39 cm long and it is to be shared between 3 people. How much does each person get? (sharing meaning)

I can create a visual representation to demonstrate why dividing by a fraction is different from diving by a whole number..e.g. ask children the children to make a visual representation to show the difference between these two division tasks:There is 3 kg of flour. A cake needs a 1/3 kg to bake a cake. How many cakes can they make? (3kg ÷ 1/3 kg)= 9 cakesThere is 3kg of flour. This is used to make 3 cakes. How much flour goes in each cake? (3kg ÷ 3cakes)= 1kg per cake

I can create word problems to demonstrate my understanding of why dividing by a fraction is different from diving by a whole number.e.g. give the children 8÷⅓ and 8÷3. Ask them to create word problems to demonstrate the difference between the two

I can solve word division problems involving fractions.e.g. provide word problems and ask how did you solve this using visual representation? How can we use notation to demonstrate your thinking?A grocer gets 7kg of rice delivered. She has to package the rice into bags that contain ¼ kg: How many bags can she make?A baker uses 3/8 of a cup of sugar for each batch of cookies he makes. He has 5 cups of sugar. How many batches of cookies can he make, including fractions of a batch?At camp a jug of lemonade contains 4 litres. The camp leader will give out 2/3 litres servings of the lemonade. How many servings can be given out?

Example of linking annotation and notation:At camp a jug of lemonade contains 4 litres. The camp leader will give out 2/3 litres servings of the lemonade. How many servings can be given out?The bar represents 4 litres

DIVIDING FRACTIONSLearning Outcomes I can distinguish between two meanings of division- measurement meaning and sharing meaning.e.g. ask the children to make a visual representation to show the difference between these two division tasks:The ribbon is 39 cm long. A single serving is 3cm/ How many people can get a serving? (measurement meaning)The ribbon is 39 cm long and it is to be shared between 3 people. How much does each person get? (sharing meaning)

I can solve word division problems involving fractions.e.g. see examples below

At camp a jug of lemonade contains 2 1/2 litres. The camp leader will give out 1/4 litre servings of the lemonade. How many servings can be given out?Example of linking annotation and notation:The bar represents 2 1/2 litres

The bar now represents 5 half litres – 2 litres and a ½

2 ½ = 5/2We need to split each litre into quarters - this is 10 quarters

5/2 ( 2 and a half) multiplied by the denominator of 4 gives us 20/2 = 10 i.e. the total number of servings available5/2 ÷ ¼ = 10

A lawnmower fuel tank can hold 4 and a half litres of petrol. Each time the grass is cut the lawnmower uses ¾ of a litre of petrol. How many times can you cut the grass before needing to refuel?Example of linking annotation and notation:The bar represents 4 1/2 litres

The bar now represents 9 half litres – 4 litres and a ½

4 ½ = 9/2We need to split tank into quarters

9/2 ( 4 and a half) split in quarters is 18 quarters

We need to establish how many ¾ of a litre we haveNote: ¾ of each litre is the volume of fuel required to cut the grass (the number of shares)

Link to simplifying fractions when learners are confident with the visualisation

I can use my knowledge of simplifying fractions, decimals and percentages to solve numerical tasks (e.g. 35% of £12) I can convert between a whole or mixed number, improper fractions and decimal fractions where appropriate I can calculate percentages of an amount where the percentage given is greater than 100%

Example:The takings at the school show were 154% in comparison with the previous year.Last year, the takings came to £1500. How much did they make this year?

100% = £150050% = £7501% = £154% = £60

154% = 100% + 50% + 4% = £1500 + £750 + £60154% = £2850

I can calculate simple fractions and percentages of a quantity, with and without a calculator, and use this knowledge to solve problems in every day contexts, including percentage increase or decreaseExample:The price of a train ticket has increased by 17%It was £6 last year, how much is it now?

10% = 60p5% = 30p (half of 10%)1% = 6p2% = 12pTherefore increase is 60p + 30p + 12p = 102pTotal cost = £6 + £1.02 = £7.02 (original price is 100% new total is 117%)

e.g.The attendance at Murrayfield for the rugby was 67106.What is this to 2 significant figures? Why would this be of interest?Compare the capacity of Murrayfield with other venues.

I can use my knowledge of rounding to estimate answers to calculations and determine the reasonableness of a solution within specific contextsTry to include estimation and reasoning within the question for example circle work, money, time intervals or cutting sections of woode.g. a skeleton model of a cube of sides 6.4cm is to be built. How long must the dowling need to be in total? Rounding too early causes error with your calculation!Consider calculator work

FRACTIONS, DECIMALS AND PERCENTAGESLearning Outcomes

I can interpret and solve multi-step problems using the four operations involving fractions and decimals and can communicate and justify my strategiese.g. A farmer needs to split a field into three equal sections. The field is 32 ½ m by 18 ¼ m. What is the area of one of these sections?Encourage learners to discuss the strategies they have used and other ways in which they might come to the same solution.

I can apply my knowledge of the equivalence of a fraction, a decimal and a percentage to solve problems, justifying choice of method usede.g. Probability:Do you have a better chance of picking a blue smartie in a tube when there are 6 blue sweets, 4 red sweets and 10 green sweetsOR from a tube where 25% of the sweets are blue?

e.g. Two companies have damaged goods. One company says 32% of their stock is fault whereas the other one says only 7 out of 20 items is faulty. Which company has a better success rate?Explain your answer

I can express one value as a percentage of anotherAPPLICATIONS OF FRACTIONS, DECIMALS AND PERCENTAGESLearning Outcomes Multiplying a decimal by a decimal

See previous levels on using arrays for multiplication and developing understanding of fractions using a hundred square, then extend into decimals from this prior knowledgee.g. Start with regarding the 100 grid as a one. Colour in 0.14 of the grid. Then colour in 0.14 three times. So 0.14 x 3 = 0.42

Explore this further beyond the whole, and consider the number families ie 0.42 ÷3 = 0.14Link from the visual that 0.14 x 3 is the same as 14 x 3 then ÷ 100

I can find the original amount in a percentage calculation, when given the solution to the original probleme.g.A family pass for the zoo has increased by 20% to £240 a year. How much was it last year?

120% = £2401% = £240 / 120 = £2100% = £200 (100% is original price)NB encouraging checking of answer by adding 20% back on to see if you get back to current price

I can apply my understanding of percentages to perform calculations in a real-life context (e.g. Wages, Salaries, Bonuses, Commission) I can use the equivalence between a percentage and a decimal fraction to create a decimal multiplier for any given percentage

Eg If there is a 20% increase in the cost of electricity bills, how much would the bill be if it was £360 last year?Explore the ways of getting to a solution – eg 100% + 20% of £360 or 1.2 x £360 or 6/5 of £360 and visual representation of why these methods are all the same

GLOSSARY

Addend. A number to be added. In 7 + 4 = 11, 7 and 4 are addends, and 11 is the sum.

Algorithm. A step-wise procedure for carrying out a task.

Arithmetic rack. A setting used to explore the structures up to 20 and beyond (Abacus).

Array. Spots organised in columns and rows to show equal grouping and sharing

Associate principle. The operation of addition is associative because, when any three numbers are added: 7 + 4 + 5, the order of performing the two addition operations does not affect the sum, for example, (7 + 4) + 5 = 7 + (4 + 5). Multiplication is also associative whereas subtraction and division are not associative.

Automaticity. A capacity to quickly recall or figure out the answer to basic (e.g. 7 + 9, 4 x 8).

Base ten. A characteristic of numeration systems and number naming systems whereby numbers are expressed in a form that involves grouping by tens, tens of tens, and larger powers of ten (1000, 10,000 etc).

Base-ten materials. A generic name for instructional settings consisting of materials organized into ones, tens, hundreds and so on, such as bundling sticks and base-ten dot materials.

Base-ten thinking. Thinking of numbers in terms of one, tens, hundreds, and so on, for example thinking of 257 as consisting of 200 + 50 + 7.

Basic facts. Combinations or number bonds of the form a + b = c (basic facts for addition) or a x b = c (basic facts for multiplication) where a and b are numbers in the range 0 to 10. Also, corresponding combinations involving subtraction or division.

Canonical. The number 64 can be expressed in the form of 60 + 4. This form is referred to as a canonical (standard place-value) form of 64, whereas 50 + 14 is a non-canonical form of 64. Knowledge of canonical and non-canonical forms are useful in addition, subtraction, and so on.

Centuple. A Multiple of 100 (e.g. 100, 200, 300, 1300, 2500). This is distinguished from century which means a sequence of 100 numbers, for example from 267 to 366 or a period of 100 years.

Century. See Centuple.

Combinations. An alternative name for number bonds or basic facts, for example, 5 + 3 = 8, 8 – 2 = 6, 7 x 9 = 63, 48 ÷ by 8 = 6.

Combining. An arithmetical strategy involving combining (i.e. in a sense adding) two numbers whose sum is in the range one to 10, without counting, for example, 4 and 3, 7 and 2.

Commutative principle. The operation of addition is commutative because, for any two numbers, their sum is unchanged when the numbers are commuted, for example 7 + 4 = 4 + 7. Multiplication is also commutative whereas subtraction and division are not commutative.

Compensation strategy. An arithmetical strategy that involves first changing one number to make an easier calculation and then compensating for the change, for example 17 + 38: calculate 17 + 40 and subtract 2.

Complementary addition. A strategy for subtracting based on adding up, for example 82 – 77 is solved as 77 + ? = 80, 80 + ? = 82, answer 5.

Conceptual place value (CPV). An instructional topic focusing on developing students facility to increment and decrement flexibly by one, tens, hundreds, and so on. CPV is distinguished from conventional place value, that is, the conventional instructional topic that is intended to provide a basis for learning formal written algorithms.

Conventional place value. See Conceptual place value.

Coordinating units. Conceiving of a unit fraction and a whole simultaneously. This involves knowing how to iterate a unit fraction such as one-third to form a whole.

Counting by ones. A range of strategies used to solve arithmetical tasks. Some examples are, counting-on, counting-back and counting from one. Contrasted with non-counting (non-count-by-ones) strategies, that is, arithmetical strategies which do not involve counting by ones such as adding through ten, using a double, using a five-structure.

Decade. See Decuple.

Decrementing. See Incrementing.

Decimalising. Developing base-ten thinking, that is, approaches to arithmetic that exploit the decimal (base-ten) numeration system, such as using 10 as a unit, and organising calculations into 1s, 10s and 100s.

Decuple. A multiple of ten (e.g. 10, 20, 30, 180, 240). Distinguished from decade which means a sequence of 10 numbers, for example, from 27 to 36 or a period of 10 years.
