Dear Family Member:

In class, students used towers of cubes to learn how to find two kinds of averages, the mean and the median. You can look back at the previous pages in this section to see how this is done. In the next lesson, students will learn how to compute an average using calculators.

Use pennies or small building blocks to build towers to solve the following problems. You will need about 30 pennies or blocks.

  1. Linda counted the number of plants her mom has in each room in the house. She filled in the following data table.
    1. Find the median number of plants in the house.
    2. Find the mean.
