Example Question #32 : Reason With Shapes And Their Attributes
What portion of the circle is striped?
A third of the circle is striped
A fifth of the circle is striped
A fourth of the circle is striped
Half of the circle is striped

Example Question #41 : Reason With Shapes And Their Attributes
If I cut a circle into fourths, how am I changing the size?
The four pieces will be different sizes.
The four pieces will be bigger than the circle.
The four pieces will be smaller than the circle.
The four pieces will be the same size as the circle
The four pieces will be smaller than the circle.
When we cut something in fourths, we get four smaller pieces that equal each other. If we put those pieces back together, we’d get the original size of the circle.
