Count Forwards: 10-20

Estimating means giving your best guess. Use the clues to help you make a really good guess before you actually count the number of objects.

Example

Look at the number of objects from left to right -  they are going up by one each time.

 If there are 12 musical notes, 11 leaves, and 10 blue flowers, then there are likely to be 9 pink flowers.

First, estimate and then count the number of pink flowers. Write the correct number below.

?	10	11	12

Answer 

We have the sequence  ?, 10, 11, 12

What number comes before 10?

It is 9.

There are 9 pink flowers.
