Worksheet Overview

This activity is about finding 1 less than a given number.

 

boy counting

 

We do this by taking 1 away from the given number.

When we take 1 away, we go to the whole number just before the number we started with.

 

Example 1

Write the number that 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

 


Example 2

 

Write the number that is:

 

1 less than 50

 

Answer

50 - 1 = 49

 

Don't be put off because your new number has a different number of tens - it is still the number that comes before 50.

 

When we count we go ........47, 48, 49, 50

49 is the number just before 50.

 

So, the answer is 49

 

Now it's time to have a go at some questions. How do you feel about that?
