Lesson 8

Slides, Flips, and Turns

Est. Class Sessions: 2
X

Mathematical Standards

4.G.A
Draw and identify lines and angles, and classify shapes by properties of their lines and angles. (4.G.A.3)

Standards for Mathematical Practice

MP1.
Make sense of problems and persevere in solving them.
MP2.
Reason abstractly and quantitatively.
MP3.
Construct viable arguments and critique the reasoning of others.

Students will investigate the transformations (slides, flips, and turns) of shapes. They will analyze, describe, and create quilt patterns and will describe how shapes move from one position, or orientation, to another.

Content in this Lesson

Materials Preparation

Quilt Designs. Find some images of quilt designs. Look for images that are created using the different types of transformations: flips, slides, and turns. Be prepared to share these images with the class.

Core Squares. Ask students to cut the core squares from the Core Square with Large Green Triangle and the Core Square with Large Orange Triangle pages in the Student Activity Book. Ask students to store the core squares in an envelope.

Geometry Word Chart. Prepare to add a sheet or two of chart paper to the Geometry Word Chart during Part 2 of the Lesson. Allow enough room for words, phrases, and student-generated examples for words related to slides, flips, and turns. See Before the Lesson.
