Standard

Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.

Student language:

• "I can name and draw shapes."
• "I know triangles, quadrilaterals, pentagons, hexagons and cubes."

Explanation

About the Math, Learning Targets, and Rigor

This standard calls for students to identify (recognize) and draw shapes based on a given set of attributes. These include triangles, quadrilaterals (squares, rectangles, and trapezoids), pentagons, hexagons and cubes.

Example

Teacher: Draw a closed shape that has five sides. What is the name of the shape?

Student: I drew a shape with 5 sides. It is called a pentagon.

Guidelines for 2.G.1

• Students use the vocabulary word “angle” in place of “corner” but they do not need to name angle types.
• Pentagons and hexagons should appear as both regular (equal sides and equal angles) and irregular.
• If students are only shown equilateral (each side the same length) triangles then when they see scalene or isosceles triangles, they do not recognize them as triangles even though they have three sides. Make sure you are always showing students various types of shapes and not just the regular shapes that they see in pattern blocks and on posters.
