Essential Question
How can you use models to find equivalent fractions?
Answer:
Two fractions are equivalent (equal) if they are of the same size or are at the same point on a number line.

Investigate
Materials Texas Go Math Grade 3 Lesson 3.4 Answer Key Model Equivalent Fractions (1) sheet of paper Texas Go Math Grade 3 Lesson 3.4 Answer Key Model Equivalent Fractions (2) crayon or color pencil

Two or more fractions that name the same amount are called equivalent fractions. You can use a sheet of paper
to model fractions equivalent to \(\frac{1}{2} \text {. }\)

A. First, fold a sheet of paper into two equal parts. Open the paper and count the parts.
There are 2 equal parts. Each part is \(\frac{1}{2}\) of the paper.
Shade one of the halves. Write \(\frac{1}{2}\) on each of the halves.
Texas Go Math Grade 3 Lesson 3.4 Answer Key Model Equivalent Fractions (3)
B. Next, fold the paper in half two times. Open the paper.
Now there are 4 equal parts. Each part is \(\frac{1}{4}\) of the paper.
Write \(\frac{1}{4}\) on each of the fourths.
Look at the shaded parts. \(\frac{1}{2}\) = \(\frac{2}{4}\)
Texas Go Math Grade 3 Lesson 3.4 Answer Key Model Equivalent Fractions (4)
C. Last, fold the paper in half three times.
Now there are 8 equal parts. Each part is \(\frac{1}{8}\) of the paper.
Write \(\frac{1}{8}\) on each of the eighths.
So,
\(\frac{1}{2}\) = \(\frac{4}{8}\)
Find the fractions equivalent to \(\frac{1}{2}\) on your paper.
So,
\(\frac{1}{2}\), \(\frac{2}{4}\), and \(\frac{4}{8}\) are equivalent.

Explain how the number of sixths in a distance on the number line is related to the number of thirds in the same distance.
Answer:
The given number line is:
Texas Go Math Grade 3 Lesson 3.4 Answer Key Model Equivalent Fractions (7)
Now,
We know that,
\(\frac{1}{6}\) = \(\frac{1}{2}\) × \(\frac{1}{3}\)
So,
We will obtain the sixths by dividing \(\frac{1}{3}\) into 2 parts
Hence, from the above,
We can conclude that
The number of sixths in a distance on the number line is \(\frac{1}{2}\) times the number of thirds in the same distance

Step 1
Draw a point on the number line to represent the distance \(\frac{2}{3}\).
Answer:
The given number line is:
Texas Go Math Grade 3 Lesson 3.4 Answer Key Model Equivalent Fractions (8)
Hence,
The representation of \(\frac{2}{3}\) on the given number line is:
Texas Go Math Grade 3 Lesson 3.4 Answer Key Model Equivalent Fractions (9)

Step 2
Use fraction strips to divide the number line into sixths. At the end of each strip, draw a mark on the number line and label the marks to show sixths.
Answer:
The given number line is:
Texas Go Math Grade 3 Lesson 3.4 Answer Key Model Equivalent Fractions (10)
Hence,
The representation of the sixths on the given number line is:
Texas Go Math Grade 3 Lesson 3.4 Answer Key Model Equivalent Fractions (11)

Step 3
Identify the fraction that names the same point as \(\frac{2}{3}\).
So, \(\frac{2}{3}\) = \(\frac{4}{6}\)

Jason cut a sandwich into three equal pieces and ate two of the pieces. Carl cut a same-size sandwich into six pieces. Carl ate the same fraction of his sandwich as Jason did. What fraction of the sandwich did Carl eat?
Texas Go Math Grade 3 Lesson 3.4 Answer Key Model Equivalent Fractions (48)
Answer:
It is given that
Jason cut a sandwich into three equal pieces and ate two of the pieces. Carl cut a same-size sandwich into six pieces. Carl ate the same fraction of his sandwich as Jason did
Now,
According to the given information,
The number of pieces Jason ate the sandwich = \(\frac{2}{3}\)
Now,
Let the number of pieces Carl ate be: x pieces
So,
The number of pieces Carl ate the sandwich = \(\frac{x}{6}\)
So,
\(\frac{2}{3}\) = \(\frac{x}{6}\)
x = 4 pieces
Hence, from the above,
We can conclude that
The fraction of the sandwich did Carl eat is: \(\frac{4}{6}\)
