This worksheet is about finding 1 less than the given number.
We do this by taking one away from the given number.
When we take one away, we go to the whole number just before the number we started with.
Example
Write the number which is:
1 less than 33
Answer
33 - 1 = 32
When we count we go.... 30, 31, 32, 33.
32 is the number just before 33.
So, the answer is 32
