10. PROBLEM OF THE DAY WHAT STRATEGY DID YOU USE TO SOLVE? 1. 2. 3.

11. You will need to get 10 centimeter tile pieces out of your baggie. Thumbs up when you’re ready to move on. Is there another way we could rearrange our centimeter cubes to form a DIFFERENT rectangle that still has an area of 10 cm? TRY IT! Each side of the centimeter tile is 1 cm long. Each tile is one square centimeter. Since we have 10 centimeter cubes, what is the area of our rectangle? 10 square centimeters! 1 row of 10 cm cubes =10 square cm!

12. Get out grid paper. How is this paper like the centimeter tiles? Each square is the same size as one tile! Shade the grid paper to represent the rectangle you made with the centimeter tiles. Remove a tile from your rectangle, making sure tiles all still touch to form a rectangle. What is the area of the rectangle now? 9 cm! How can you change the rectangle on the grid paper to have the same area?

13. Put away your centimeter tiles and get out 10 inch tiles. Let’s start by arranging them into 2 equal rows just like we did with the centimeter tiles. Let’s rearrange our inch tiles to form a DIFFERENT rectangle that still has an area of 10 square inches. Each side of these tiles is 1 inch long. One tile is 1 square inch. Since we have 10 square inch tiles, what is the area of our rectangle? 10 square inches! 1 row of 10 inch tiles =10 square inches!

14. Turn over your grid paper to the inch side How is this paper like the inch tiles? Each square is the same size as one tile! Shade the grid paper to represent the FIRST rectangle you made with the inch tiles. Remove TWO squares from your rectangle. What is the area of the rectangle now? 8 square inches!
