Understanding improves if they can relate
mathematical symbols to some meaningful
experiences they have or they can
visualize (Intuitive level)

Hundred Chart
After learning numbers one to hundred,
Hundred chart activities would provide the
children with visual and manipulative
experience that will help them to learnBasic Operations such as addition,
subtraction, multiplication and division.

Skip Counting
Start from 1, count by 3’s with the help ofyour hundred chart.
Circle the numbers with a blue colourpencil
Write down the number in sequence asyou circle it.
This skip counting activity for numbers
actually provide visual experience forlearning

How would you use skip counting to
prepare the children for learning
multiplication facts?
Multiply by 2 : Start with 2, skip counting in 2’s
Multiply by 3 : Start with 3, skip counting in 3’s

FIVE-FRAME
• Put a red bean in the first square in the Frame.
• Fill up the remaining square with the green beans
• How many red and green beans in the five-frame?1 red and 4 blue
1 + 4 = 5

Five-FRAME
How many red and green beans in the five-frame?
1 red and 4 blue, 1 + 4 = 5
1 and 4 are ‘Partners of 5’ Fill in other combination of the red and green beans
in the Five - Frame.
Can you write down other ‘Partners of 5 ?

Prepare the children for word problems through
Manipulatives.
•I have 3 green bean. How many more green
beans do I need to fill up the five-frame.
•I have 5 red beans, Ann has 2 red beans less thanme. How many beans does Ann have?
•Write down equations for subtraction from 5.

Partners of Ten
•Use red and green beans to fill up the ten-frame
•Then write down the pairs that make ten: ‘Partners of10’

Five-Frame is useful in Year 1 for additionand subtraction up to 5
Ten – Frame for addition and subtractionup to 10
partner 5 and partners of 10 are important
in learning basic addition facts andsubtraction facts.
Partners of 10 is useful in subtraction
involving regrouping

Twenty-frame
How do you use the twenty-frame to teach subtraction
with regrouping if your student only had mastery of‘partners of 10’?
17 - 9 =
Would you take away 9 squares from the row of ten or
the row of 7?

1 7- 9 1
8
If you take away 9 squares
from 10, left behind 1 square. Add 1 to the 7 in the second
row , you get 8
( 1 + 7 = 8)For subtraction involving regrouping, you can take the partner
of 10 for the subtrahend (9), which is 1, and add it to the ones
digit in the minuend (7)

1 5- 6 4
If you take away 6 from 10, left
behind 4. Add the 4 to the 5 in the
second row , you get 9
( 4 + 5 = 9)
For subtraction involving regrouping, you can take the partner
of 10 for the subtrahend (6), which is 4, and add it to the ones
