Standard 2.G.1: 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 (Note: 1.G.2 explores solid figures including cubes, right rectangular prisms, right circular cones, and right circular cylinders. Second graders should also be comfortable with these figures.)

Quarter 4
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.

Enduring Understanding

Geometric attributes (such as shapes, lines, angles, figures, and planes) provide descriptive information about an object's properties and position in space and support visualization and problem solving.

Essential Questions

How does geometry better describe objects?

Vocabulary (online dictionary, visual mathematics dictionary, HCPSS Vocabulary Cards)

rectangle, row, column, angle, face, triangle, quadrilaterals, pentagons, hexagons, cube

About the Math

Spatial sense is an important component of geometry. Spatial sense is an intuition about shapes and the relationships among shapes. Rich experiences with shape and spatial relationships help develop students' spatial sense. Students begin this experience by working with two and three dimensional shapes. As students look at how shapes are alike and different, they begin to see the properties of shapes. Students need to see shapes in different sizes and orientations. Triangles should be more than equilateral and not always show the vertex at the top. Students need to sort shapes based on their similar characteristics. Students need to experiment with composing and decomposing shapes so they can see how to form larger shapes from smaller shapes. A rectangle can be make up of two triangles.

Shapecard BLMs

Property Lists for Quadrilaterals (Van De Walle, K-3, p 207). Create worksheets with a variety of parallelograms, rhombi, rectangles, and squares. On each sheet there should be three or four examples of that category of shape in a variety of orientations. Assign students to work in groups of three or four to one type of quadrilateral. Their task is to list as many properties as they can. Each property listed must be applicable to all of the shapes on their sheet. They will need a blank index card to check right angles, to compare side length, and to draw straight lines. Mirrors may also be used to check line of symmetry and tracing paper to check angle congruence. Encourage students to use the words "at least" when describing how many of something: for example, "rectangles have at least two lines of symmetry," since squares- included in the rectangles- have four.

Have students prepare their properties lists under these headings: Sides, Angles, Diagonals, and Symmetries. Groups then share their lists with the class and eventually a class list for each shape will be developed.
