Decimals and fractions (age 10+)
Associate a fraction with division and calculate decimal fraction equivalents for simple fractions (e.g. 3/8 = 0.375); recall and use equivalences between simple fractions, decimals, and percentages in different contexts
Typical age: 10–11 years
“If your child sees 3/8 written on a worksheet, can they convert it to a decimal — and also say roughly what percentage that is?”
