Which of the models shows halves?
The model in C shows 2 equal parts, or halves.
How many of the halves
are shaded in C?
How can we say and write this fraction?
We say, "one half." We write this as
Which of the models shows thirds?
The model in A shows thirds.
Does B show fourths? Why?
Yes; there are 4 equal parts.
In D, the pieces are not the same shape. Does this model show fourths? Why or why not?
Yes; equal parts have to be the same size, but not the same shape. We can cut the rectangle in half. Then, we can cut each of those halves into fourths.
E has 4 parts. Does it show fourths? Why or why not?
No, because the parts are not the same size.
Which models with equal parts show that the whole
A, B, and D.
What fraction of each of these models are shaded?
A = 3 thirds; B = 4 fourths.
D = 4 fourths.
