The Attributes of Two-dimensional Figures

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.
Printable Worksheets And Lessons
- Name That Shape Step-by-step
Lesson- We describe three properties of a shape and you name
- Guided Lesson -
Name a shape, color another, and then find out which one is different.
- Guided Lesson Explanation
- This was ridiculously hard for me to explain.
- Practice Worksheet
- We ask you to draw and name shapes.
- Matching Worksheet - Match the shapes to their names.
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.
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.
