Standards: 3.G.1 - Understand that shapes in different categories (for example, rhombuses, rectangles, and others) may share attributes (for example, having four sides), and that the shared attributes can define a larger category (for example, quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.

Objectives: 

1. Identify two-dimensional shapes and their attributes

2. Draw two-dimensional shapes, given attributes

3. Compare and Contrast attributes of two-dimensional shapes

4. Categorize two-dimensional shapes according to attributes

5. Identify and draw two-dimensional shapes that do not belong to a given category

Objectives:

1. Identify quadrilaterals and their attributes

2. Draw quadrilaterals, given attributes

3. Compare and Contrast attributes of quadrilaterals

4. Identify shared attributes of different quadrilaterals

5. Categorize quadrilaterals according to attributes

6. Identify and draw quadrilaterals that do not belong to a given category

Standards: 3.MD.8 - Solve real-world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.

Objectives:

1. Understand the difference between perimeter and area

2. Use side lengths to find the perimeter of a shape

3. Find an unknown side length given the perimeter of the shape

4. Understand that rectangles with the same area can have different perimeters

5. Understand that rectangles with the same perimeter can have different areas

Standards: 3.G.2 - Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole.

Objectives:

1. Partition a shape into equal areas

2. Express the area of each equal part as a unit fraction of the whole shape.

3. Partition the same shape in a different way.
