Stepping Stones

Activity Overview

Students use volume formulas and proportional reasoning to calculate the amount of concrete needed to make stepping stones of a specific size.

Before the Activity

See the attached PDF file for detailed instructions for this activity

Print pages 38 - 44 from the attached PDF file for your class

During the Activity

Distribute the pages to the class.

Follow the activity procedures:

One serving of lemonade uses 11 parts water, 1 part lemon juice, and 2 parts sugar

Calculate and record in a table how many tablespoons of each ingredient is used to make 1, 2, 3, and 4 servings

Use centimeter cubes to fill a decimeter cube box

Calculate the volume of the box

Identify the dimensions of each stepping stone

Calculate the volume of one stepping stone

Place the decorative object and 5-mm layer of gravel

Find the volume of gravel and concrete required for one stepping stone

Determine the total amount of gravel and concrete needed to build the whole pathway

Create a chart showing the calculations and the final information

After the Activity

Students view each chart.

Review student results

As a class, discuss methods and formula used

Re-teach concepts as necessary
