I created this SmartBoard lesson according to the Everyday Math teacher edition for 2nd grade. It contains mental math, math message, a review of writing numbers to 10s, 100s, and 1000s as well as ordering numbers on a number line. This lesson is designed to teach old and new skills and compliments the spiraling method used in Everyday Math. Later lessons will contain interactive games as well as a thorough review of the Math Boxes pages. I hope you find this activity helpful in your classroom and an efficient and time conscious lesson!
