The Similar Figures Scavenger Hunt is a hands on activity that allows students to move around and measure items within the classroom, and then calculate the new measurements of similar figures.
The activity is introduced by telling students that two groups of new students will be joining us. One is a group of hobbits and the other is a group of giants. We will need to make adjustments to the classroom to accommodate their size. The students will help by gathering measurements and calculating the new sizes of items we need to special order for the new students.
Each student will need a ruler. This could be a partner or individual activity. For students who struggle, you can have them round each measurement to the nearest inch, or limit their measurements to a few objects. For advanced students, there is a challenge problem at the end to convert inches to decimeters.
This activity can be used to demonstrate proportions of similar figures. It can also be used to practice multiplying fractions and mixed numbers, measuring objects, and converting units of measurement.
