# 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. ### Pattern Blocks - Examples

- Lesson plan -

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

### The Coordinate Plane

- Lesson plan -

Graph points on a coordinate plane (first quadrant only). ### 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. ### Measure Angles

- Activity -

Find the angle (in degrees) between two lines.

### 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 -

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

### Transformations in the Coordinate Plane

- Lesson plan -

Identify, describe and perform transformations involving translations, reflections, and rotations. ### 3D Views

- Activity -

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

### Angles

- Lesson plan -

Identify angles as acute, right or obtuse. Find the measure of an angle using a protractor. ### Volume of a Prism

- Lesson plan -

Find the volume of rectangular prisms and triangular prisms. Compare volumes of prisms of equal height. Find the volumes of similar prisms.

### Perimeter & Area

- Lesson plan -

Understand the concept of perimeter and area. Find the perimeter and area of simple polygons. Find the area of rectangles and squares using length x width. ### Area - Grid based

- Activity -

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

### Two & Three Dimensional Shapes

- Lesson plan -

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