This Fluency Activity is a part of the Lesson 2, Unit 4, Grade 5. This fluency activity reviews concepts from Grade 4 and Grade 5 Module 3. For English language learners or students who must review the relative size of fractional units, folding square paper into various units of halves, thirds, fourths, and eighths can be beneficial. Allow students time to fold, cut, label, and compare the units in relation to the whole and each other. Project a tape diagram partitioned into 2 equal parts. Shade 1 of the parts.
