If there is one resource all parents and carers should have at home when helping their child to understand numbers and the number system, it would be a laminated 100 square.
Read on to find out why and how to use yours at home!
This visual representation of numbers up to 100 really helps children to understand how numbers are related to each other and secure their knowledge of number and place value (the value of each digit in a number)
3 Fab Ideas For Using a 100 Square
1. + 10 / - 10
A 100 Square is a fantastic resource for explaining visually to your child how to add 10 (move down 1 row) or - 10 (move up 1 row). They can clearly see that the tens number increases by 10 each time and the units digit stays the same.
E.g 37 +10 = 47
Ask your child questions such as:
“ Put your finger on 37.
Add 10 (Child moves down one row).
What number are you on now?”
(They should be on 47.)
Take away 10.
e.g. 43 - 10 = 33
"Find the number 43.
Take away 10 ( Child moves up 1 row). What number are you on now?”
As your child gets more confident, ask them to record the number sentence as well: e.g. 18 + 10 = 28 43 - 10 = 33
2. Identifying odd and even numbers
If you have a laminated 100 square, asking your child to colour in each even number in a certain colour will really make clear the pattern with odd and even numbers.
Once your child knows that even numbers end in 0, 2, 4, 6 or 8, they will very quickly be able to find all the even numbers on the 100 square. They will also be able to see that numbers ending in 2 go down in a vertical line to the bottom of the 100 square (as do numbers ending in 4, 6, 8 and 0!)
Exactly the same activity can be done for odd numbers!
3. Any times tables
By circling multiples of a number children can really see the pattern. See below for an example of the 3 x table:
Children can do this for any x table. The visual image really helps to secure their understanding of number.
As your child becomes more confident 100 squares are also fantastic for finding other number patterns (e.g. square numbers -a number multiplied by itself e.g. 4 x 4 = 16 so 16 is a square number-, prime numbers etc).
We really hope these ideas help your young mathematician to understand numbers a little more. A 100 Square really is a fantastic resource just to have around the house for your little one to refer to and to reinforce the number system. Enjoy!
