Arithmetic. Fractions. Percentages. Ratio. Proportion. Standard form. Bounds. The marks look small until students bleed them everywhere.
Before using this full Number Study Kit, weak students should complete the rescue page below:
Use it first if the student makes errors with signs, brackets, fractions, decimals, powers, roots, standard form or estimation. This is the non-calculator survival page.
Use this next if the student confuses fractions, decimals, percentages, percentage change, discount, profit/loss or reverse percentage.
Use this when the student freezes on word problems involving share, per, speed, scale, exchange rates, best value, direct proportion or inverse proportion.
Accuracy, Rounding, Bounds and Units
Use this when the student gets the method right but loses marks through rounding, units, bounds, context rounding or final answer format.
Use this map to jump mentally through the Number chapter. Chapter 1 is large, so each skill has its own small label.
