Click here for our other Year 1 Worksheets.

A number bond is just a maths fact that a pair of numbers when added together make a given total. For example the number bonds for 10 are 0+10=10, 1+9=10; 2+8=10, 3+7=10, 4+6=10, 5+5=10 etc, and the number bonds for 20 are
0+20 = 20, 1+19 = 20, 2+18 = 20 etc.

Number bonds like times tables are something which a child should know instantly without needing to think - therefore lots of practice by play and worksheets are essential to memorise these number relationships.

Number bonds help children to understand how numbers work - that a number can be made up of parts, and the sum of the parts is the whole. Number bonds are also a good introduction to the fact that subtraction is the inverse of addition - A child learning that 4 add 6 equals 10 is also learning that 10 minus 6 is 4 and that 10 minus 4 is 6.
