maybe u can try replacing the word 'is' with the '=' sign. But your child must always remember when it comes to subtracting, always big number minus small number.


1. 5 is 1 less than _
5 = _ - 1
2. _ is 1 less than 3
_ = 3 - 1

1 less than 7 is _____
7 - 1 = _

8 is ___ more than 3.
8 = _ + 3

Hope my 'another' way helps u.
