More Organized Counting

Houses in a Row

This problem challenges students to figure out how many different color combinations are possible for a row of houses, if no two houses can be painted exactly alike. Use large color squares and triangles to model this problem for students as an introduction to combinations.

NOTE:  Have students explain their thinking and how they organized their information.  It is also important to ask students how they knew that they had found all of the possible combinations.
