# Number Jumbler

Based on the classic number puzzle. Move the numbers into the correct order.

Decimals show numbers that are in between two whole numbers. Decimals can be added and subtracted like whole numbers. You need to take care when comparing two decimals to work out how to order them, and make sure you are reading them correctly.

# Number Pairs

Want to speed up your adding up? You need number pairs. Repair the slide by dragging two numbers that add up to 20.

# Ordering Fractions

Use our testing room to find out what different fractions are worth. In order to compare fractions, you need to change them so they have the same denominator.

# The number system

Make a number between 425 and 450 by dragging the digits into the right places in the number machine.
