Estimation with Blocks Worksheet – Guess and Check (PDF)

This estimation with blocks worksheet introduces a critical math skill: Making a smart guess. Before picking up the cubes, we want students to look at the object and visualize the length.

How to use this “Guess & Check” Activity:

• Step 1: The Guess: Look at the picture (e.g., a hammer or a spoon). Write down how many cubes you think it is in the “My Guess” cloud.
• Step 2: The Check: Count the actual row of blocks underneath the object.
• Step 3: Compare: Was your guess close?

Using this estimation with blocks worksheet helps children develop “number sense” and prevents them from just mindlessly counting without thinking about size.
