Kitchen Floor Tiles

This Kitchen Floor Tiles activity & project also includes:

An interesting way to look at the kitchen floor is to count the number of tiles in the border. Fred starts with four white floor tiles and writes an expression for the number of tiles needed for the colored border. Algebra learners are to verify that Fred’s expression is correct. Emma wants to increase the initial number of white tiles to five, but her expression is incorrect. Help your number crunchers draw out Emma’s tile pattern and come up with the correct expression. Finally, ask them to develop an expression if the initial white row is n tiles.
