# Lesson 2: Understanding Equivalence

Understanding Fractions - Grade 3 and Grade 4 | Lesson 2 | 60 minutes

A 60 minute lesson in which students will identify and explore equivalent fractions.

## Lesson Plan

### Tuning In

- Watch the video
*The Easiest Way To Learn Fractions With LEGOs*on YouTube. After watching, ask the students:- Which unit fractions were made by cutting up the block of Lego?
- How many different ways was one half represented in the video?
- What is the word used to describe fractions that are written differently, but have the same value?

### Teacher Instruction

- Discuss the definition of equivalent fractions, as outlined on slide 10 of the
*Understanding Equivalent Fractions PowerPoint.*Encourage the students to add some more equivalent fractions to the list of examples. - Display and discuss the annotated example on slide 11 and complete the whole class example on slide 12.

### Guided/Independent Learning

- Read through the review activity on slide 13. Answer any questions the students may have about the task and allow the students a small amount of time to complete the activity e.g. ten minutes. Encourage the students to share some of the equivalent fractions they created for each image.
- Place the students into pairs. Allow the students to use the
*Equivalent Fractions Cards*to play a variety of card games. Some examples of such games include ‘Memory’ (students must match equivalent fractions to win a pair), ‘Snap’ (students must snap when equivalent fractions appear on top of one another) and ‘Go Fish’ (students must ask their partners for equivalent fractions to make a pair).

### Wrapping Up

- To revise the lesson’s content, watch the
*Equivalent Fractions Song For Kids*video on YouTube. Encourage the students to sing along to the chorus.

## Differentiation

### Extending Students

- Place more confident students together in pairs for the card games, so that they may challenge and extend each other.

### Supporting Students

- Allow less confident students to play the card games in a small group with the support of a teacher or teacher aide.

## Resources

#### Common Core State Standards alignment

Grade 3 > Standards for Mathematical Practice > Number & Operations - Fractions > Develop understanding of fractions as numbers > **CCSS.MATH.CONTENT.3.NF.A.3**

Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.

Grade 3 > Standards for Mathematical Practice > Number & Operations - Fractions > Develop understanding of fractions as numbers > CCSS.MATH.CONTENT.3.NF.A.3 > **CCSS.MATH.CONTENT.3.NF.A.3.A**

Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line.

Grade 3 > Standards for Mathematical Practice > Number & Operations - Fractions > Develop understanding of fractions as numbers > CCSS.MATH.CONTENT.3.NF.A.3 > **CCSS.MATH.CONTENT.3.NF.A.3.B**

Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3. Explain why the fractions are equivalent, e.g., by using a visual fraction model.
