This unit reviews fractions at the third-grade level but can be used at higher grades as an assessment. The exercises include comparing fractions by writing <, >, or = between them to indicate greater, lesser, or equal. Some problems ask for ordering fractions from least to greatest or greatest to least, challenging the student's ability to compare and sequence fractions correctly. There are also tasks involving rewriting improper fractions as mixed numbers, adding fractions to find their sum, and subtracting fractions to find the difference. As a challenge, some questions require solving for a variable in simple equations involving fractions.
