Type: Audio/Video

Overview:

Two-Headed Monster has arrived to demonstrate the rectangle shape. The problem is, they don't seem to know what a rectangle looks like. Instead, they pull out two triangles. They discover, however, that two triangles can be used to make one rectangle. This resource teaches shapes.

Content Standard(s):
Mathematics
MA2019 (2019)
Grade: K
21. Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (number of sides and vertices or "corners"), and other attributes.

Example: Having sides of equal length.

21. Build and draw shapes which have defining attributes.
a. Distinguish between defining attributes and non-defining attributes.
Examples: Triangles are closed and three- sided, which are defining attributes; color, orientation, and overall size are non-defining attributes.

22. Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.
