Addition with Manipulatives

 Addition with Manipulatives

Grade Level: 1st

My goal for this lesson is to help first graders conceptualize addition through the use of manipulatives, such as objects and pictures.

Objective: Students will be able to add using manipulatives and write the addition equation. 

Materials:

-Two large containers

-Red math blocks

-Blue math blocks

-Dry-erase boards

-Worksheets

Manipulatives activity: Grab and Add

Fill two containers with math cubes, one with red cubes and one with blue cubes. Students will reach into the containers and grab a small handful of cubes from each. They will count the objects and write the addition sentence and sum on a dry-erase board. I.e. if a student pulls six red blocks and 4 blue blocks, the addition sentence will be 6 + 4 = 10.

Mathematical Standard:

CCSS.MATH.CONTENT.1.OA.A.1

Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

CCSS.MATH.CONTENT.1.OA.C.5

Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
