Fractions can be tricky, but looking at them visually can help your students understand them. This lesson will help students with equivalent fractions, number lines, and making real world connections.
Students will be able to identify and represent equivalent fractions on a number line.
Introduction (10 minutes)
- Put students in groups of 3.
- Give each group a different amount of candy in multiples of 3.
- Instruct students to divide the candy evenly in the group.
- Have each group share how many pieces each person ends up with.
Explicit Instruction/Teacher Modeling (5 minutes)
- Ask your student what equivalent means. Explain that equivalent means equal.
- Have them discuss the importance of understanding equivalent fractions. Ask them to discuss how fractions are used in the real world.
- Use a picture of a pizza to show students how two different pizzas can be cut into different sized slices and how each person can get the same amount.
Guided Practice/Interactive Modeling (10 minutes)
- Draw two number lines on the whiteboard.
- Ask your students to call out two different fractions.
- Identify their points on the number lines, placing one fraction on each number line. Do this in different colors, and have students use colored pencils in their own math journals.
- Have the class identify whether or not the fractions are equivalent or not.
Independent Working Time (10 minutes)
- Write the following fractions on the board: 2/3=3/6, 2/5=4/6, 1/3=2/6, and ½=4/8.
- Have students work independently in their journals to draw their own number lines and identify the fractions on the number line.
- Ask them to identify whether the fractions are equivalent or not.
- If the fractions are equivalent, have them put true as their answers, and have them put false if the fractions aren't equivalent.
- Make sure your students show all their work.
- Enrichment: Have students draw pictures of real world objects that can be divided evenly.
- Support: Work with these students in a small group, and model for them the first problem on the board before they begin their independent work. Show them more pictures of real world objects that can be divided evenly.
Assessment (10 minutes)
- Give students the Equivalent Fractions worksheet.
Review and Closing (5 minutes)
- Write two fractions on the board, and have some volunteers come up to draw the fractions on number lines and identify whether they are equivalent.
