1/2LT’s Rainbow Numbers Factory


Posted by moya | Posted in Maths | Posted on February 19, 2014

This week we have learnt all about rainbow numbers. Our rainbow numbers are pairs of numbers that add up to 10. Like 7+3, 5+5, 9+1, 2+8 and 6+4. They are called rainbow numbers because if you draw a loopy line between them on a number line…. it makes a rainbow! Today in 1/2LT we played a game called cover up to help us practice our rainbow numbers. Our rainbow numbers are useful for counting to 10, adding to 10, subtracting from 10 and for solving problems. We want to get to know them really, really well, just like lightning!

Here is how to play rainbow number cover up –

1. Get a number board from 0-10. Available below on the blog.

This is a 0-10 board.

This is a 0-10 board.


2. Get a ten sided die. (At home you might like to write the numbers 0-10 on pieces of card and draw them out of a bag or bowl).



3.  Get two sets of counters (or buttons). Each player needs a different colour.

4. Play Rock, paper, scissors to work out who goes first.


5. Roll the die (or choose a number if  you are at home)


6. When you roll a number, you put your counter on the rainbow number partner of that number. For example, if you roll a 6 you put it on 4. If there is already one of your opponents counters on that square, you can push it off. If you get the rainbow number wrong, you don’t get to put a counter down.

A 6, do you know the rainbow number?

A 6, do you know the rainbow number?

7. Take turns with your partner.

8. Keep playing until all the squares are covered. The person with the most counters on the board wins. The winner gets to have the first roll the next game.


Have FUN!!!!!!!
