This activity is about finding 1 less than a 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 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?
