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.

Mathematics (2019) Grade(s): KG

MA19.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.“

UP:MA19.K.21

Vocabulary

  • Attributes

Knowledge

Students know:
  • attributes of shapes (sides, corners, vertices, faces, edges, etc.).
  • Informal language to describe these components.

Skills

Students are able to:
  • Use geometric reasoning and attributes to compare and contrast a variety of shapes.

Understanding

Students understand that:
  • geometric shapes can be grouped into classes of shapes that all seem to be alike based on their visual characteristics.
Mathematics (2019) Grade(s): KG

MA19.K.23

Skills

Students are able to:

2019 ALCOS

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.
