# Define Quadrilateral By Similarities Math Games

4 games

In this series of games, your students will learn that shapes in different categories may share attributes, and that the shared attributes can define a larger category. The Define Quadrilateral By Similarities learning objective — based on CCSS and state standards — delivers improved student engagement and academic performance in your classroom, as demonstrated by research. This learning objective directly references 3.G.A.1 as written in the common core national math standards.

## Concepts Covered

Analyze shapes for their properties. Explicitly relate and combine classifications. Quadrilaterals are four-sided figures with 4 vertices. A rectangle is a four-sided shape where every angle is a right angle (90 degrees) and opposite sides are parallel and of equal length. A rhombus is a four-sided shape where all sides have equal length, opposite sides are parallel, and opposite angles are equal. A square has equal sides, opposite sides are parallel, and every angle is a right angle.

A parallelogram has opposite sides parallel, opposite sides equal in length, and opposite angles are equal. A trapezoid has a pair of sides parallel. Squares, rectangles, and rhombuses are all parallelograms. A square is also a rectangle. Compare 2-D shapes by their properties. Irregular quadrilaterals may not fit any of the subcategories of quadrilaterals. Draw quadrilaterals that do not meet any of the subcategories.
