A focused Grade 3 learning session for Unit Fractions using visual models, worked examples, strategy guidance, and a short mastery check.
Student goal: I can identify and describe unit fractions.
Unit Fractions means using equal parts, number lines, and clear fraction language to describe parts of a whole.
Question: Look at the rectangle below. It is divided into \(6\) equal parts, and one part is shaded. What fraction is shaded?
Why it works: The rectangle is divided into \(6\) equal parts. One part is shaded, so the shaded fraction is \(\frac{1}{6}\) (one-sixth).
Answer: \(\frac{1}{6}\)
Question: Which picture shows \(\frac{1}{3}\) shaded?
Answer: Picture C
Question: Look at the circle. It is divided into \(4\) equal parts. One part is shaded. What fraction is shaded?
Answer: \(\frac{1}{4}\)
Question: A garden is divided into \(6\) equal sections. What unit fraction represents one section?
Why it works: A whole divided into \(6\) equal sections has each section as \(\frac{1}{6}\) (one-sixth).
Answer: \(\frac{1}{6}\)
Unit Fractions becomes easier when students connect the question to a model, use clear steps, and explain why the answer fits.
Equal parts first, fraction name second.
Use scratch paper. The explanation matters more than simply seeing whether the choice is correct.
A pizza is cut into \(8\) equal slices. What fraction represents one slice?
Answer D: \(\frac{1}{8}\)
When a whole is cut into \(b\) equal parts, one part is the unit fraction \(\frac{1}{b}\). Here \(b=8\), so one slice is \(\frac{1}{8}\).
A candy bar is divided into \(4\) equal pieces. What is the fraction name for one piece?
Answer A: \(\frac{1}{4}\)
When something is split into \(4\) equal parts, one part is called one-fourth, or \(\frac{1}{4}\).
Look at the rectangle below. It is divided into \(6\) equal parts, and one part is shaded. What fraction is shaded?
Answer B: \(\frac{1}{6}\)
The rectangle is divided into \(6\) equal parts. One part is shaded, so the shaded fraction is \(\frac{1}{6}\) (one-sixth).
A circle is divided into \(3\) equal slices. One slice is one unit fraction. Which fraction name is correct?
Answer B: \(\frac{1}{3}\)
A circle with \(3\) equal parts has each part as \(\frac{1}{3}\) (one-third).
Sam cuts a brownie into \(2\) equal pieces. What fraction is one piece?
Answer C: \(\frac{1}{2}\)
A whole divided into \(2\) equal parts gives each part the name \(\frac{1}{2}\) (one-half).
Look at the picture. The rectangle is divided into equal parts, and some parts are shaded. Which fraction is shaded?
Answer A: \(\frac{1}{4}\)
The rectangle has \(4\) equal parts, and \(1\) is shaded, so the fraction is \(\frac{1}{4}\) (one-fourth).
A rope is divided into \(8\) equal sections. What unit fraction describes one section?
Answer A: \(\frac{1}{8}\)
When a whole is divided into \(8\) equal parts, one part is the unit fraction \(\frac{1}{8}\) (one-eighth).
Which picture shows \(\frac{1}{3}\) shaded?
Answer C: Picture C
Picture C shows a rectangle divided into \(3\) equal parts with \(1\) part shaded, which is \(\frac{1}{3}\).
A pie is cut into \(6\) equal slices. Ava eats one slice. What fraction of the pie does Ava eat?
Answer C: \(\frac{1}{6}\)
The pie has \(6\) equal slices. Ava eats \(1\) slice, so she eats \(\frac{1}{6}\) of the pie.
Look at the circle. It is divided into \(4\) equal parts. One part is shaded. What fraction is shaded?
Answer B: \(\frac{1}{4}\)
The circle is divided into \(4\) equal parts. One part is shaded, so the shaded fraction is \(\frac{1}{4}\) (one-fourth).
A sheet of paper is folded to make \(2\) equal halves. What unit fraction is one half?
Answer C: \(\frac{1}{2}\)
Folding a sheet into \(2\) equal parts creates two halves, each one is \(\frac{1}{2}\).
