Stack 10% and 1% chunks of a bill to build a tip or sales tax and read the new total off the money scale.
A percent scale sits aligned to a dollar scale, and the child stacks ten-percent and one-percent chunks — each one a tenth or hundredth of the bill — up to the target rate, then reads the tip or tax straight off the money scale. Building the percent from friendly chunks makes percent-of-a-number a mental-math skill instead of a formula. The game builds percent, tips, sales tax, and mental math. Best for Grades 5–6.
A free, no-signup, no-ads math game for Grades 5–6 — practising percent, percent-of-a-number, tip, sales-tax, mental-math. Play in your browser on the KidsDoMath games hub or explore more Money & Finance games.
