Unit 2: Stretching and Shrinking: Similarity

The next unit in your child’s mathematics class this year is Stretching and Shrinking: Similarity. Its focus is geometry, and it develops understanding of and skill in the use of concepts of similarity.

UNIT GOALS

In this unit, your child will use properties of similar figures to explore reductions and enlargements such as those made on copy machines. Similarity will also be used to estimate the height of real objects (such as buildings and flagpoles) and the distance across large areas (such as ponds).

The problems are designed to help students begin to reason proportionally by scaling in geometry situations. By the end of this unit, your child will know how to create similar figures, how to determine whether two figures are similar, and how to predict the relationship between lengths and areas for two similar figures. The next unit, Comparing and Scaling, continues to develop proportional ideas in numerical, rather than geometric, contexts.
