• Marker
• Plastic milk jug
• Utility knife
• Three clear jars (same size and shape)
• Poster board

4. Place the materials in the center, and post the directions where everyone can see them.

Use:

2. Use the scoop to fill each jar with one ingredient.

3. Estimate the number of cups of the ingredient there are in each jar. Write down the estimate.

4. Use the measuring cup to count how many cups are in each jar. Put the ingredients back in their boxes.

5. Compare the actual number of cups to the number that was estimated.

6. Write down what you found out about the number of cups in each jar.
