Geometry

Third Grade | Geometry

Standard: CC.2.3.3.A.1;CC.2.3.3.A.2 Identify, compare, and classify shapes and their attributes. Use the understanding of fractions to partition shapes into parts with equal areas and express the area of each part as a unit fraction of the whole.

I can...

explain that shapes in different categories may share attributes, and that the shared attributes can define a larger category.
recognize rhombi, rectangles, and squares as examples of quadrilaterals
draw examples of quadrilaterals that do not belong to any of these subcategories.
partition shapes into parts with equal areas.
express the area of each part as a unit fraction of the whole.

Vocabulary: Quadrilateral / Quadrangle, Polygon

LEARNING SCALE

With help, the student demonstrates partial success at 2.0 and 3.0.

I can recognize and identify 2-dimensional shapes.

I can identify the names of shapes. (square, rectangle, rhombus, trapezoid, triangle, and parallelogram)

I can identify the names of 3-dimensional shapes: Prism, sphere, pyramid, cylinder, cube

I can explain that shapes in different categories may share attributes, and that the shared attributes can define a larger category.
