﻿ Kindergarten Mathematics Module 1, Topic D | EngageNY

## Kindergarten Mathematics Module 1, Topic D At this point in the module, students have been engaged in meaningful, varied counting, learning that quantities of objects have a numerical value. Topic D opens with beginning to understand the meaning of zero in the context of groups of objects. Up until now students have only been asked to identify numerals to 5. The first two lessons in this topic introduce writing the numerals 0–3. Using the students’ understanding that numbers correspond to a value, they can now order numbers in relation to a counting sequence. Lesson 14 builds upon the prior decomposition Lesson 11 from Topic C. Students see both the expression 2 + 1 (Topic C) and the equation 3 = 2 + 1 (Topic D) describing a stick of three cubes decomposed into 2 parts (K.OA.3). The difference now being that the equal sign is shown. Take note that the sum is written first to demonstrate something whole being separted into two parts as opposed to two parts being joined to make a whole.
