## Kindergarten Mathematics Module 4, Topic E Topic E expands student exploration of numerical relationships to include 9 and 10. Returning to work with number bonds after introducing addition and subtraction provides students with a reminder about the part–part–whole relationships that underlie these operations. Students will explicitly discuss the relationship between addition and subtraction in Topic H. In Lesson 25, students work intensively with the number pairs of 9 as they demonstrate different combinations of sleeping bears and honey-tree hunting bears using counters and record with number bonds. Lesson 26 gives students the opportunity to decompose 9 into number pairs using representations of fingers, linking cubes, and number bonds. In the Debrief, they explore patterns in the number pairs. Lessons 27 and 28 follow this same lesson structure for the number 10. In all four lessons, the decompositions are discussed or recorded using number bonds, drawings, and number sentences. This topic’s decomposition situations, like those in Topic B, are put together both addends unknown addition equations modeled by the equation C = ___ + ___ (K.OA.3).
