Playing with Percents (Part 2)

Playing with Percents (Part 2) is a Grade 6 mental-math activity for finding benchmark percentages of numbers. Students use relationships such as 50% = one half, 25% = one fourth, and 20% = one fifth to calculate percentages without a calculator. Carefully chosen numbers let students focus on the structure of the percent rather than on complicated arithmetic.

Use it as a whole-class warm-up when students are developing flexible strategies for percent of a number. Comparing 50%, 25%, 20%, and 10% of the same quantity helps students see how benchmark percents relate to one another.
