(6)  Geometry and measurement. The student applies mathematical process standards to analyze attributes of two-dimensional shapes and three-dimensional solids to develop generalizations about their properties. The student is expected to:

(A)  classify and sort regular and irregular two-dimensional shapes based on attributes using informal geometric language

(B)  distinguish between attributes that define a two-dimensional or three-dimensional figure and attributes that do not define the shape

(C)  create two-dimensional figures, including circles, triangles, rectangles, and squares, as special rectangles, rhombuses, and hexagons

(D)  identify two-dimensional shapes, including circles, triangles, rectangles, and squares, as special rectangles, rhombuses, and hexagons and describe their attributes using formal geometric language

(E)  identify three-dimensional solids, including spheres, cones, cylinders, rectangular prisms (including cubes), and triangular prisms, and describe their attributes using formal geometric language

(F)  compose two-dimensional shapes by joining two, three, or four figures to produce a target shape in more than one way if possible

(G)  partition two-dimensional figures into two and four fair shares or equal parts and describe the parts using words

(H)  identify examples and non-examples of halves and fourths.

In this lesson plan, the students will be able to distinguish between defining attributes and non-defining attributes of shapes. This lesson also allows the students to come up with their own definition of the shapes and to draw it out.

This blog provides two activities that students may work on in the classroom. The first activity is using playdoh and have the students cut out the equal parts, such as in halves and fourths. The second activity is "fraction flowers" where each petal represents halves or fourths in different shapes. These are fun activities as it can be a future reference that the students may use late on and it is a pleasing visual to look at.
