## Buying Tile## Materials:-
(for each group of four students)
- measuring tape
- one ceramic tile (varying in size for each group)
- graph paper
- calculator
- ruler
## Tasks:-
Suggestion: Divide the tasks between your group members
- You are going to tile an area that is 100 square feet in area. Remember that there are 12 inches in a foot.
- Given the sample tile, how many tiles will you need to buy?
- Draw a diagram of your tiled area on the graph paper.
- Write your group's reasoning. Use the back of the paper if necessary
- If each tile costs 37 cents, how much money will it cost to complete the project?
## Evaluation:- Teacher observation during the group activity.
- Each group presents their findings orally to the class using two overhead transparencies. One is to list the steps of their process. The other is to draw a diagram to illustrate their tiled area.
