	Proficient 3 pts	Approaching Proficient 2 pts	Developing 1 pts
Area of Squares	Proficient The dimensions are labeled correctly. The amount of boxes each square contains corresponds to the correct computation of the formula for Area of a regular quadrilateral.	Approaching Proficient The dimensions are incorrectly labeled. The amount of boxes each square contains corresponds to the correct computation of the formula for area of a regular quadrilateral.	Developing The dimensions are not labeled. The amount of boxes each square contains is incorrect
The creation of the right Triangle	Proficient The squares are correctly placed to form a right triangle. The dimensions are accurate: the hypotenuse is the longest side and the two shorter sides are the legs.	Approaching Proficient The squares are correctly placed to form a right triangle but the dimensions may be inaccurate, the hypotenuse may form the leg.	Developing The squares do not form a right triangle. The dimensions of the right triangle are off.
Creativity/Pop!	Proficient The squares are aesthetically stimulating, colorful and attractive to the eye. There was an effort to make this display look presentable and beautiful.	Approaching Proficient The squares are colored and neatly done. There was an effort to make the display look presentable.	Developing Squares are not colored. Display shows minimal effort.
