# 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.

### Nets of Solids

- Activity -

Practice nets of solids by matching the correct 3d shape with its net fold.

### 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.

### Area - Side lengths

- Activity -

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

### 3D Views

- Activity -

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

### Solid Shapes

- Lesson plan -

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

### Angles

- Lesson plan -

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

### 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.

### Area - Grid based

- Activity -

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

### Perimeter - Grid based

- Activity -

Determine the perimeter of a shape on a grid.

### Measure Angles

- Activity -

Find the angle (in degrees) between two lines.

### Map Location

- Activity -

Practice spatial skills by finding the correct image that is taken on a map.

### Net of a Polyhedron

- Activity -

Learn the properties of the net of a polyhedron.

### 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.
