Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
General Information
Subject Area: Mathematics
Grade: K
Domain-Subdomain: Operations and Algebraic Thinking
Cluster: Level 2: Basic Application of Skills & Concepts
Cluster: Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from. (Major Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Virtual Manipulatives

Counting on and back:

This interactive Flash applet supports the exploration of numbers to 100 by simulating a 100-bead string. A teacher or child can move all or some beads to the left or right to add and subtract. The controls allow users to move beads individually or 10 at a time to model different counting and calculation strategies. Users can hide or show the numbers represented by the beads. This applet lends itself well to use on an interactive white board. A PDF guide to this collection of teaching applets is cataloged separately.

Type: Virtual Manipulative

Five Frame :

This applet contains four games (How Many?, Build, Fill, and Add) that utilize a frame with five slots for students to place objects, which helps students develop counting and addition skills.
