Breaking Apart Method: Addition

Breaking Apart Method: Subtraction

Lattice Method: Multiplication

Double Division Method: Division

CCSS.Math.Content.2.NBT.B.5

This method is similar to the standard algorithm because, the student still adds the numbers in a vertical manner; first beginning with the ones category and continuing to the left to the hundreds, thousands, and so on.This algorithm is different than the standard algorithm because it is not necesary for the student to regroup the numbers because they create simpler numbers before the addition step.

This method is similar to the standard algorithm because, the student still multiplies each number distributively and then will add the products together. This method is beneficial because it creates a visual.

This method is similar to the standard algorithm because, the student still contemplates how "many" of one number will go into the "bigger" number using the division bar.
