Percentage Computations & Rational Conversions

Mathematics & Quantitative Reasoning

Your child can move fluidly between fractions, decimals, and percentages, and can calculate percentages out of whole amounts during transactions.

In real life

You spot a "30% off" sign in a shop, and your child works out the actual sale price in their head before you reach the till. They might also check whether the "¾ full" fuel gauge really matches 75%.
