## The Attributes of Two-dimensional Figures

#### Aligned To Common Core Standard:

**Grade 5 Geometry** - 5.G.3

What Are the Common Attributes of Two-dimensional Figures? Students, usually in 3rd grade often face this difficulty in describing two-dimensional figures. Two-dimensional figures are described through their attributes, and there are attributes in these figures that are common. For example, there are different sub-categories of shapes such as rhombus and rectangle with common attributes, i.e., 4 sides. These attributes can also be extended to quadrilaterals. A 2-D figure lies on the two axes, the X-axis and the Y-axis. Hence the name two-dimensional figure. One of the most common and basic attributes of a 2D figure is that it has a line segment, with the exception of a circle. A line segment has endpoints, i.e., a starting point and an ending point. The order of the endpoints doesn’t matter in the 2D figures. Take the example of an oval and a circle. Both have curves and are entire round shape figures. The only difference between them is that a circle has one radius throughout. These worksheets and lessons will help students be able to name 2D shapes based on the number of sides and vertices.

#### Homework Sheets

As one student wrote in, "These worksheets are like looking for a needle in the haystack."

- Homework 1 - Choose the correct word that describes the shape. If the lines of the shape were to continue, they would never run into each other.
- Homework 2 - It looks like a letter a 'Trapezoid' ,but we can’t be sure unless all the lines are parallel. Since the lines will never run into each other, we know all lines are parallel.
- Homework 3 - Define and draw the shape of Rhombus.

#### Practice Worksheets

It is really neat to see what some students come up with since there are multiple answers for a few of these.

- Practice 1 - Draw shapes that match all these criteria and name the shape.
- Practice 2 - Rhombus: A 4-sided flat shape with straight sides where all sides has equal length. Also opposite sides are parallel and opposite angles are equal.
- Practice 3 - Choose the correct word that describes the shape. If the lines of the shape were to continue, they would never run into each other.

#### Math Skill Quizzes

The quizzes really cover everything that I have ever seen on this standard in one question. Is it a bit much?

- Quiz 1 - Identify the shape and record the correct number of corners and sides for each plane figure on the lines below.
- Quiz 2 - Name and circle the different shape.
- Quiz 3 - Color the shapes and write their names.
