### 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.

### Pattern Blocks - Examples

- Lesson plan -

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

### 3D Shapes

- Activity -

Explore and describe geometric attributes in three-dimensional shapes.

### 3D Views

- Activity -

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

### The Coordinate Plane

- Lesson plan -

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

### 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.

### Angles

- Lesson plan -

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

### Views of Three Dimensional Figures

- Lesson plan -

Draw front, side and top views of three-dimensional figures built from cubes. Build a three-dimensional figure when given the front, side and top views.

### Area - Side lengths

- Activity -

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

### Nets of Solids

- Activity -

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

### Triangle Classification

- Lesson plan -

Identify, define, describe, and accurately represent triangles.

### Solid Figures

- Lesson plan -

Identify solid figures including prisms, pyramids, cones and spheres. Identify the nets of solid figures.

### 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.

### Area of complex shapes

- Activity -

Calculate the area of parallelograms, triangles and trapezoids.

### Solid Shapes

- Lesson plan -

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