Grade 7:  The Learning Equation Math

 Number Operations Exploring Integers - Optional Refresher pp 28-9 Activity 12.04 Refresther pp 30-1
Learning Objectives:

The student will:

• add integers concretely, pictorially, and symbolically.

Drag the appropiate number of tiles to each side of the + sign to model the question. When your model matches the question, move all of the tiles to the left of the + sign. If you have yellow and red tiles, try placing a red tile on top of the yellow tile to show a zero pair. Repeat with all of the zero pairs to see the integer sum modelled by each set of tiles.

 Adding Integers Explanation 3 + 4 = 7 6 + 7 = 13 -3 + -4 = -7 -6 + -7 = -13 -1 + 3 = 2    1 positive tile cancels the negative tile. -2 + 4 = 2    2 positive tiles cancel the 2 negative tiles. -3 + 5 = 2    3 positive tiles cancel the 3 negative tiles. -3 + 1 = -2    1 negative tile cancels the positive tile. -4 + 2 = -2    2 negative tiles cancel the 2 positive tiles. -5 + 3 = -2    3 negative tiles cancel the 3 positive tiles.
