Evaluation for 4.3b
Materials provide interleaved practice opportunities with previously learned skills and concepts across lessons and units.
The grade 5 materials provide systematic interleaved practice through cumulative practice sections and multi-session lesson structures spiraling previously learned skills. For example, in the grade 5, Unit 1 "Review," students practice volume, division, and place value representation. Each lesson includes multiple sessions that give students time to build skills and understand concepts. Skills from earlier units are also practiced in new ways, helping students focus on key grade-level work while reinforcing what they previously learned. Specific examples include Unit 2, "Cumulative Practice," with three sets: breaking apart figures for volume (Unit 1, Lesson 3), multiplying multi-digit numbers (Unit 1, Lesson 4), and dividing multi-digit numbers (Unit 1, Lesson 5). Unit 4, "Cumulative Practice" spans multiple units: multiplying fractions in word problems (Unit 3, Lesson 22), dividing with unit fractions (Unit 3, Lesson 23), division word problems (Unit 3, Lesson 24), and adding/subtracting fractions (Unit 2, Lessons 12–13). The Cumulative Practice demonstrates how grade 4 division concepts support grade 5 volume and advanced operation applications.
