Index: 4.2B Grade 4 CPI 2

 

Standard: 4.2 - Geometry and Measurement

 

Strand: B - Transforming Shapes

 

Cumulative Progress Indicator: 2 - The student will describe and use geometric transformations (slide, flip, turn).

 

Grade: 4

 

Sample Activities:

 

·        Students use stuffed animals or two-sided paperdolls to show movements in the plane: slides, flips, and turns. They discuss how all slides (or flips or turns) are alike.

 

·        Students create borders from a single simple design element which is repeated using slides, flips, and turns

 

·        Students study and describe the use of transformations in Pennsylvania Dutch hex signs, and then they design their own.

 

·        Students discuss transformations found in nature, such as the symmetry in the wings of a butterfly (a flip), the way a honeycomb is formed (slides of hexagons), or the petals of a flower (turns).

 

·        Students create quilt designs by using geometric transformations to repeat a basic pattern.

 

Sample Assessment Question:
