A set of 40 colourful houses as well as some windows with number facts related to number bonds to 10 and and 20. Also includes some blank windows for children to fill in their own facts.
 
Children cut out a house and stick the corresponding windows on to show the complete fact family.
 
For example - four windows could be:
 
6 + 4 = 10
4 + 6 = 10
10 - 4 = 6
10 - 6 = 4
 
A great resource for children to practise number bonds and to understand that addition and subtraction are inverse operations.
 
24 pages in total - 20 pages of houses (2 per page) and 4 pages of windows (including some blank windows).
