#### Worksheet Overview

Freddie the frog loves jumping around on number lines. He always likes to make a clever number sequence. Use your finger to follow the jumps that he makes.

Example:

Count the frog's jumps to work out the missing numbers in the sequence.

Are the numbers getting bigger or smaller? Is Freddie going backwards or forwards?  Can you see a pattern?

What could the missing numbers be?

If we look at 55 and 54, 54 is smaller than 55 so the numbers are going backwards.

To find A, this will be the number before 54 which is 53.

To find B, this will be the number before 52 which is 51.

Let's put the numbers into the pattern and check they work:

Yes, they do work! Our missing numbers were 53 and 51.

Let's try the questions now.
