Content Area: Math
Index: 4.2A Grade 3 CPI 1
Standard: 4.2 - Geometry and Measurement
Strand: A - Geometric Properties
Cumulative Progress Indicator: 1 - The student will identify and describe spatial relationships of two or more objects in space. · Direction, orientation, and perspectives (e.g., which object is on your left when you are standing here?)
Grade: 3
Sample Activities:
· Blindfolded students are given real objects to touch and then, with the blindfolds removed, select the objects from a collection of visible objects.
· Students work through the Will a Dinosaurs Fit? lesson that is described in the First Four Standards of this Framework. They discuss the size of the different dinosaurs and arrange them from smallest to largest.
· Students predict what shape will result when a small piece is cut out of a folded piece of paper in different ways (along a diagonal, across a fold or a corner, or in the center) and the paper is then unfolded.
· Students compare the sequence of objects seen from different points of view. For example, from the classroom window, the swings are to the left of the monkeybars, but the relationship is reversed if the objects are viewed from the blacktop facing the classroom.
· Students predict and draw what the shadow of an object placed between a light and a screen will look like.
