Know Your Numbers: Jumping Backwards in Tens

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 missing numbers in the sequence.

Pop your finger on the first number, then follow the jumps. Are the numbers getting bigger or smaller? Is Freddie going backwards or forwards? Can you see a pattern? What could the missing number be? What could the next number be?

Answer:

A = 60

B = 50
