How accurate are robots? Groups draw lines by moving robots backwards and forwards by one rotation of the wheels. Using the appropriate formula, they determine the percent error in the length of the lines in relation to the calculated...

Class members learn how to estimate the total costs involved to design and build a bridge by including design, material, equipment, and labor costs. The activity includes a discussion about the trade-off between cost and aesthetics.

Second graders practice their estimation skills using blocks. In this math lesson, 2nd graders explain how estimating makes addition easier. They complete a worksheet after the lesson to reinforce new learning.

How much rain can that cloud make? Through a simulation, the class estimates the amount of candy rain contained in different cup clouds. After probing the clouds using different methods, class members adjust their estimates. Participants...

Our final proposal for the cost of the bridge requested is ... In the last segment in a series of 10, pairs work together to develop a proposal for a city bridge design. The class completes a cost comparison between concrete and steel to...

Students practice estimating distances by analyzing a map. In this length measurement activity, students view a map with a distance key and use their measurement skills to estimate the distance between two cities. Students utilize an...

Students design and build a balance using LEGO, string, and a set of standard metric weights.
