This applies to all other types of polygons as well. Be sure to vary their exposure to hexagonal shapes and give them opportunities to work with and draw hexagons that are not regular. If students have too much exposure to regular hexagons and not enough of irregular hexagons, they may believe that a regular hexagon is the only type of hexagon.

Thinking that an irregular hexagon is not a hexagon.

Rotational symmetry is the number of times a shape fits into itself when rotated around its center. A line of symmetry on a two-dimensional shape divides the shape equally into two symmetrical pieces. Lines of symmetry are often confused with rotational symmetry.

Thinking that figures can’t have more than one line of symmetryĢD shapes can have more than one line of symmetry or no lines of symmetry.

Rectangles have the same interior angles, but they do not have the same side lengths. Squares are the only regular quadrilaterals. This Math Packet is very well organized, Easy-to-Use, and includes an Answer Key.Shapes - 2D Shapes - Find the Number of Sides and Vertices for Each Shape - Worksheets/TestTarget Group: 1) Grades: 3 and 4PRODUCT DESCRIPTION: This product is great for teachers that are looking for a 2D S.

Thinking that a rectangle is a regular polygon.

Identify line-symmetric figures and draw lines of symmetry.Ĭlassify two-dimensional figures in a hierarchy based on properties.įor example, thinking that a pentagon is a hexagon or vice versa.

Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes. Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Identify shapes as two-dimensional (lying in a plane, “flat”) or three-dimensional (“solid”).Ĭompose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape and compose new shapes from the composite shape.
