“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?”

Full guide and materials

Activity. 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

What to notice. Convert 3/8 to 0.375 by dividing 3 ÷ 8 • State that 1/5 = 0.2 = 20% from memory • Use fraction–decimal–percentage equivalences to compare 30%, 1/3, and 0.35 and put them in order
