Use counting strategies, number patterns, and models as a means for solving basic addition and subtraction fact problems.

Remarks

Decomposing considered key for understanding the addition and subtraction relationship. Teachers should include one-step word problems.

Strategies include: Doubles, Doubles + 1, Doubles - 1, Grouping 10s, Counting on, and Counting back

Example: 6 + 7 = 13, 6 + 6 + 1 = 13

Example: 13 - 7 = 6 and (13 - 3) - 4 = 6 (using the knowledge that 3 + 4 = 7)

Lesson Plans

Dangerous Doubles (Doubling Numbers):

This lesson teaches students to use the strategy doubling numbers and doubles plus or minus one in order to use mental math to add one-digit numbers. The students are engaged in learning through the read-aloud of "Double the Ducks" by Stephen Murphy and then get to work with a partner to draw doubles and write equations that relate to their drawings. Students individually work on solving word problems using these strategies and manipulatives as necessary to solve.

Type: Lesson Plan

Out of Sight Missing Addends:

Students will learn how to use manipulatives to solve missing addends in math problems.
