About this booklet… This booklet has been put together to assist you with your maths. The booklet

summarises what we have discussed, learned and practised in class together. Read

through the summary and have a practise at using some of the strategies. If you don’t

understand a topic, or part of a topic, remember you can always ask for help!

Use mathletics for a fun way to practise your maths and what we have learned in

class.

Remember the 5G motto, have a go, do you best and take pride in everything you

do.

Term 1, Week 4:

NUMBER FOCUS: Place Value

MEASUREMENT FOCUS: Perimeter This week during our ‘Number’ lesson, we have focused on ‘Place Value’. Place Value is the value of a digit, depending on its place or position in a number.

3 0 4 1 The number 3041 is made up of the digits 3,0,4 and 1. If we were to label this numbers place value parts, it would look like this:

Thousands Hundreds Tens Ones 3 0 4 1

*Remember 0 still holds a place! 3041 in words: Three thousand and forty one. 3041 in place value parts: 3 thousands, 0 hundreds, 4 tens and 1 one. We also spoke about renaming numbers. Renaming is giving another name to a number using its place value parts. We can rename the number 23: 23= 2 tens and 3 ones or 23= 23 ones 23 can look like this:

This week during our ‘Measurement’ lessons, we have focused on ‘Perimeter’. Perimeter is the total distance around a shape or the total sum (remember sum is the same as add) of all the shapes sides.

During, we measured the perimeter of the bat tennis court and discussed different strategies of working out the perimeter of regular shapes. Many of us discovered that we did not need to measure every line of the bat tennis court – this was because much of the bat tennis court is a square; each length of a square is the same size. When we were looking at the perimeter of irregular shapes, we spoke about looking for the missing length.

For this shape, we would draw an imaginary dotted line: we know one sides total is 14m. The other side is 2cm shorter because the shape changes. Therefore, we must subtract or take 2m away from 14m.

Term 1, Week 5: NUMBER FOCUS: Place Value

MEASUREMENT FOCUS: Area This week during our ‘Number’ lesson, we have focused on ‘place value with decimals’. Place value with decimals looks like this: Hundreds Tens Ones Tenths Hundredths

3 0 4 . 1 5

304.15 in words: Three hundred and four and 1 tenth and 5 hundredths 304.15 in place value parts: 3 hundreds, 0 tens, 4 ones, 1 tenth and 5 hundredths. We played a card game exploring tenths and hundredths. This week during our ‘Measurement’ lessons, we have focused on ‘Area’. Area is the measurement INSIDE a shape. To work out the area, you can multiply the length and width of a shape. When we write a measurement representing area, we write the unit squared: for example 2cm2

This is because we are measuring two dimensions of the shape – length and width! For example:

The black line is the perimeter.

This blue part is the area.

Term 1, Week 6: NUMBER FOCUS: Multiplying by 10 MEASUREMENT FOCUS: Area and Perimeter Review

This week during our ‘Number’ lessons, we have focused on ‘multiplying by 10’. We completed an activity outside on the oval with MAB and looked at the relative size of multiplying by ten with real objects (eg. People). This week during our ‘Measurement’ lessons, we reviewed area and perimeter. We created this poster in a small group.

We also measured the area and perimeter of our classroom door. It is important to remember that area is the inside and the perimeter is the outside or boundary.
