Describing Shapes
Describing Shapes
Objectives
In this lesson, students focus on identifying, describing, and drawing two-dimensional shapes, and becoming familiar with the shapes’ attributes. Students will:
- name circles, triangles, squares and rectangles.
- explain attributes of a shape.
- draw examples of triangles, circles, squares, and rectangles.
Essential Questions
How are spatial relationships, including shape and dimension, used to draw, construct, model, and represent real situations or solve problems?
How can geometric properties and theorems be used to describe, model, and analyze situations?
How can recognizing repetition or regularity assist in solving problems more efficiently?
How can the application of the attributes of geometric shapes support mathematical reasoning and problem solving?
- How can the application of the attributes of geometric shapes support mathematical reasoning and problem solving?
- How are spatial relationships, including shape and dimension, used to draw, construct, model, and represent real situations or solve problems?
Vocabulary
- Circle: A closed two-dimensional shape made by a curved line with a center point. All points of the line are equal distance from the center point.
- Compare: To look at two or more things and find ways they are the same and different.
- Rectangle: A two-dimensional shape with four right angles and two sets of parallel lines.
- Square: A two-dimensional shape with four right angles and four equal sides.
- Triangle: A polygon with three sides and three angles.
