Students use our lego measurements to underestimate and over estimate this giant firefighter’s construction time and LEGO block quantity. Then students average their class estimates and compare to the real time and and quantity.
In this activity students decide what equipment and supplies are necessary, estimate how much that will all cost, confer with classmates to refine their lists, and then research to find out more accurately how much it will probably cost to send them back to school. This activity could be used for students in upper elementary school all the way to high school. It offers an opportunity for kids to estimate, research, reason, calculate and communicate with each other.
