Cluster: Level 2: Basic Application of Skills & Concepts
Cluster: Reason with shapes and their attributes. (Additional Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Educational Game

Shape & Solid Exploration:

In this game, learners use clues to identify mystery shapes. Use everyday objects (like from the pantry) as the shapes. It is important for learners to be able to describe a shape with correct math vocabulary and to be able to visualize a shape in their head.

Type: Educational Game

Formative Assessments

Turning a Square:

Students are shown a square in various orientations and asked if it is still a square.

Type: Formative Assessment

Is it Still a Rectangle?:

Students discuss the defining and non-defining attributes of rectangles.

Type: Formative Assessment

Draw Triangles:

Students draw two triangles and are prompted to describe the triangles in terms of defining attributes.

Type: Formative Assessment

Attributes of a Hexagon:

Students draw two hexagons and are asked to justify their drawings.

Type: Formative Assessment

Lesson Plans

Must or Might: Exploring Defining Attributes of 3-D Figures:

The purpose of this lesson is for students to examine defining and non-defining attributes of 3-dimensional figures. Students compare and contrast various representations of 3-dimensional figures (including real-world objects) to determine what the solid must have, compared to what it might have. This exploration is also supported by sorting 3-dimensional figures.

Type: Lesson Plan

Shape Identifying and Sketching:

In this lesson students will describe attributes of triangles, rectangles, squares, and hexagons and identify these shapes by their attributes. Given the name of one of these shapes, students will use their knowledge of the shape's attributes to represent the shape with a sketch.

Type: Lesson Plan

Being Shapely!:

In this lesson, students will work collaboratively to identify and sketch shapes with defining and non-defining attributes.

Type: Lesson Plan

Composite Creature:

The students will use pattern blocks to build and draw new composite geometric shapes, ultimately using composite shapes to form a creature.
