Example Questions
Example Question #21 : Geometry
If I cut this rectangle in half, how many pieces will I have?
When we cut something in half, we get 
Example Question #2 : Use Rectangles And Circles To Show Halves And Fourths: Ccss.Math.Content.1.G.A.3
If I cut this circle in half, how many pieces will I have?
When we cut something in half, we get two equal pieces.
Example Question #22 : Geometry
If I cut this rectangle into fourths, or quarters, how many pieces will I have?
When we cut something into fourths, or quarters, we get four equal pieces.
Example Question #4 : Use Rectangles And Circles To Show Halves And Fourths: Ccss.Math.Content.1.G.A.3
If I cut this circle into fourths, or quarters, how many pieces will I have?
When we cut something into fourths, or quarters, we get four equal pieces.
Example Question #4 : Use Rectangles And Circles To Show Halves And Fourths: Ccss.Math.Content.1.G.A.3
If I cut a rectangle into fourths, how am I changing the size?
The four pieces will be smaller than the rectangle
The four pieces will be bigger than the rectangle
The four pieces will be the same size as the rectangle
The four pieces will be different sizes
The four pieces will be smaller than the rectangle
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 rectangle.
Example Question #23 : Reason With Shapes And Their Attributes
If I cut a rectangle in half, how am I changing the size?
Each piece will be different sizes
Each piece will be bigger than the rectangle
Each pieces will be smaller than the rectangle, they will be half the size.
Each piece will be the same size as the rectangle
Each pieces will be smaller than the rectangle, they will be half the size.
When we cut something in half, we get two smaller pieces that equal each other. If we put those pieces back together, we’d get the original size of the rectangle.
Example Question #6 : Use Rectangles And Circles To Show Halves And Fourths: Ccss.Math.Content.1.G.A.3
If I cut a rectangle into two parts, I am cutting it in ___________.
Half
Thirds
Fourths
Quarters
Half
When we cut something into two parts, which means the same thing as cutting it in half.
Example Question #1 : Use Rectangles And Circles To Show Halves And Fourths: Ccss.Math.Content.1.G.A.3
What portion of the circle is striped?
A fifth of the circle is striped
A third of the circle is striped
A fourth of the circle is stripedd
Half of the circle is striped
Half of the circle is striped
The circle is divided into two equal sizes. One side is striped and one side is blue. So half of the circle is striped.
Example Question #5 : Use Rectangles And Circles To Show Halves And Fourths: Ccss.Math.Content.1.G.A.3
A fourth means the same thing as a ____________.
Third
Quarter
Fourth
Fifth
Quarter
A fourth and a quarter mean the same thing because both words mean 
Example Question #8 : Use Rectangles And Circles To Show Halves And Fourths: Ccss.Math.Content.1.G.A.3
If we have two rectangles of the same size, and we cut one of them in half, and one of them in fourths, which pieces will be smaller?
The rectangle that we cut into fourths
They will both have pieces of bigger sizes than the original rectangles
The rectangle that we cut into half
They will both have pieces of the same size
The rectangle that we cut into fourths
Cutting an object into four pieces makes the pieces smaller because a fourth is smaller than a half.
