  • Assign Home Practice Parts 1 and 2. Part 2 provides practice with the order of operations and the students play Operation Target.
  • Assign DPP items A–D. In Bit C, students practice finding the mean and the median runs in baseball games.
  • Challenge D can be used as a Problem of the Week to further develop students' understanding of the concept of average.

Math Facts. DPP Bit A asks students to self-assess their fluency with the division facts for the 2s and 3s using Triangle Flash Cards and record their progress on their Division Facts I Know charts. Task B provides practice using fact families for the 2s and 3s.
