**Essentials Question**

How Can Different Fractions Name the Same Part of a Whole?

Visual Learning Bridge

The Chisholm Trail was used to drive cattle to market. Ross’s herd has walked \(\frac{1}{2}\) the distance to market. What is another way to name \(\frac{1}{2}\)?

\(\frac{1}{2}\) = \(\frac{}{}\) You can use fraction strips.

The fractions \(\frac{1}{2}\) and \(\frac{2}{4}\) represent the same part of the whole.

Two \(\frac{1}{4}\) strips are equal to \(\frac{1}{2}\), so \(\frac{1}{2}\) = \(\frac{2}{4}\).

Another name for \(\frac{1}{2}\) is \(\frac{2}{4}\).

You can find other equivalent fractions. Think about fractions that name the same part of the whole.

Four \(\frac{1}{8}\) strips are equal to \(\frac{1}{2}\), so \(\frac{1}{2}\) = \(\frac{4}{8}\).

Another name for \(\frac{1}{2}\) is \(\frac{4}{8}\)

Convince Me! Look for Relationships In the examples above, what pattern do you see in the fractions that are equivalent to \(\frac{1}{2}\)? What is another name for \(\frac{1}{2}\) that is not shown above?

**Essential Question**

How Can Benchmark Numbers Be Used to Compare Fractions?

Visual Learning Bridge

Keri wants to buy of a container of roasted peanuts. Alan wants to buy of a container of roasted peanuts. The containers are the same size. Who will buy more peanuts?

Compare each fraction to the benchmark number \(\frac{1}{2}\). Then see how they relate to each other in size.

So, \(\frac{2}{6}\) is less than \(\frac{2}{3}\).

\(\frac{2}{6}\) < \(\frac{2}{3}\)

Alan will buy more peanuts than Keri.

Convince Me! Make Sense and Persevere Candice buys \(\frac{2}{8}\) of a container of roasted peanuts. The container is the same size as those used by Keri and Alan. She says \(\frac{2}{8}\) is between \(\frac{1}{2}\) and 1, so she buys more peanuts than Alan. Is Candice correct? Explain.

Answer:

Candice, she was correct.

Explanation:

In the above-given question,

**Essential Question**

How Can You Construct Arguments?

Visual Learning Bridge

Clara and Ana are making rugs. The rugs will be the same size. Clara has finished of her rug. Ana has finished of her rug. Who has finished more of her rug? Conjecture: Clara has finished a greater portion of her rug than Ana.

A conjecture is a statement that you think is true. It needs to be proved.

How can I explain why my conjecture is correct?

I need to construct an argument to justify my conjecture.

How can I construct an argument?

I can

- use numbers, objects, drawings, or actions correctly to explain my thinking.
- make sure my explanation is simple, complete, and easy to understand.

Here’s my thinking…

I will use drawings and numbers to explain my thinking.

The number lines represent the same whole. One is divided into fourths. One is divided into eighths.

The number lines show that 3 of the fourths is greater than 3 of the eighths.

So, \(\frac{3}{4}\) > \(\frac{3}{8}\). The conjecture is correct.

Convince Me! Construct Arguments Use numbers to construct another math argument to justify the conjecture above. Think about how you can look at the numerator and the denominator.
