# 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.

### Coordinate system

- Activity -

Students learn to name coordinates by studying the grid. ### Area - Grid based

- Activity -

Find the area of a shape on a grid by counting squares.

### 3D Shapes

- Activity -

Explore and describe geometric attributes in three-dimensional shapes. ### Two & Three Dimensional Shapes

- Lesson plan -

Identify, compare, classify, and analyze attributes of two and three dimensional shapes.

### Plane Shapes

- Lesson plan -

Identify common plane shapes including squares, circles, rectangles, triangles. Identify polygons up to six sides. Classify shapes by common characteristics. ### Perimeter - Side lengths

- Activity -

Determine the perimeter of rectangles or compound figures using side lengths.

### Solid Shapes

- Lesson plan -

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

- Activity -

Calculate the area 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. ### Practice: Shapes and Colors

- Lesson plan -

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

### 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. ### The Coordinate Plane

- Lesson plan -

Use the coordinate system to describe the location and relative position of points and draw figures in the first quadrant.

### The Pythagorean Theorem

- Lesson plan -

Look for relationships between the lengths of the sides of a right triangle, leading to the Pythagorean Theorem. Apply the theorem to find the hypotenuse and legs of a right triangle. ### Sorting by multiple attributes

- Lesson plan -

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

### 3D Views

- Activity -

Find the correct view of a certain side of a 3D object.
