Adding & Subtracting
Overview
For this numeracy building block students will start kindergarten thinking of counting as a string of words, but then they make a gradual transition to using counting as a tool for describing their world. They must construct the idea of counting using manipulatives and other resources to see the numbers visually (dot cards, tens frames).
To count successfully, students must remember the rote counting sequence, assign one counting number to each object counted, and at the same time have a strategy for keeping track of what has already been counted and what still needs to be counted.
Only the counting sequence is a rote procedure. The meaning students attach to counting is the key conceptual idea on which all other number concepts are developed. Students will develop successful and meaningful counting strategies as they practice counting and as they listen to and watch others count.
