# Geometry Sort

### Pattern Blocks

- Activity -

Allow children to see how shapes can be decomposed into other shapes and introduce them to tiling. Build patterns, create and solve critical thinking problems, and model various math concepts.

### 3D Shapes

- Activity -

Explore and describe geometric attributes in three-dimensional shapes. ### Coordinate system

- Activity -

Students learn to name coordinates by studying the grid.

### Perimeter - Side lengths

- Activity -

Determine the perimeter of rectangles or compound figures using side lengths. ### Pattern Blocks - Examples

- Lesson plan -

This lesson contains several predesigned figures. Use pattern blocks to create the same figures.

### Perimeter - Grid based

- Activity -

Determine the perimeter of a shape on a grid. ### Plane Shapes

- Lesson plan -

Identify common plane shapes including squares, circles, rectangles, triangles. Identify polygons up to six sides. Classify shapes by common characteristics.

### The Coordinate Plane

- Lesson plan -

Graph points on a coordinate plane (first quadrant only). ### Practice: Shapes and Colors

- Lesson plan -

Students learn to recognize shapes and colors with six different exercises.

### Area - Grid based

- Activity -

Find the area of a shape on a grid by counting squares. ### Area - Side lengths

- Activity -

Calculate the area of rectangles or compound figures using side lengths.

### Distributive Property

- Activity -

Use tiling to show in a concrete case that the area of a rectangle with whole-number side lengths a and b + c is the sum of a x b and a x c. ### Solid Shapes

- Lesson plan -

Identify geometric solids including cubes, cylinders, cones, spheres, rectangular prisms, and pyramids; relate them to objects in the environment.

### Sorting by multiple attributes

- Lesson plan -

Sort items by multiple attributes, or combine attributes to form items in a matrix. ### Perimeter

- Lesson plan -

Develop strategies to determine the perimeter of rectangles and plane figures.

### Measure Angles

- Activity -

Find the angle (in degrees) between two lines.
