Learning Objectives
Students will be able to predict and explain features of shapes that are scaled by factors greater than one.
Introduction
(5 minutes)- Show your class two pictures: A model of something, and a picture of the actual item.
- Ask, “Which one is the is the real item?” Allow for student responses.
- Reveal which picture was a model. Note how a model is a version of something, but wouldn’t be very realistic, if it weren’t ‘to scale,’ or have the same features in proportion to the real thing.
- Explain that establishing features in proportion to scale means to multiply all of the dimensions by the same factor.
