Index: 4.2B Grade 3 CPI 1

 

Standard: 4.2 - Geometry and Measurement

 

Strand: B - Transforming Shapes

 

Cumulative Progress Indicator: 1 - The student will describe and use geometric transformations (slide, flip, turn).

 

Grade: 3

 

Sample Activities:

 

·        Students look at the world around them for examples of changes in position that do not change size or shape. For example, a child going down a slide illustrates a slide, a merry-go-round or hands on a clock illustrate a turn, and a mirror illustrates a flip.

 

·        Students look through and discuss the no-text book Changes, Changes by Pat Hutchins. In it, a man and a woman use the same set of building blocks to transform a house into a fire engine, then a boat, a truck, and back to a house. The students tell the story and then draw pictures to show how the blocks changed from one object to another.

 

·        Students investigate the shapes that they can see when they place a mirror on a square pattern block.
