The Eiffel Tower
measurement · Estimating height using comparative reasoning
Mental math is great for working with measurements!
The Eiffel Tower is a Grade 3 measurement-estimation activity built around comparative reasoning. Students make an initial estimate of the tower’s height, then revise their thinking as clues are added—such as comparing the height with stacks of students or giraffes. The activity keeps the mathematics focused on scale and reasonableness rather than exact recall.
Use it as a whole-class mental-math discussion when students are learning to estimate large measurements. Recording successive guesses lets students see how new information improves an estimate.
