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.
