## Snowboard Slalom

Use the arrow keys to guide the snowboarder to the correct answer. Can you answer 10 questions before the time runs out?

There are over a hundred carefully differentiated levels linked to objectives from the new maths curriculum. The game can be used to teach: Multiplication, Addition, Reading Numbers, Subtraction, Fractions of Numbers, Roman Numerals, Rounding Numbers, Division, Converting Fractions to Decimals, Converting Fractions to Percentages, and Simplifying Fractions. A full list of levels is below.
