Learning Objectives

Students will be able to draw models for fractions with various numerators and denominators.

Introduction

(10 minutes)

Begin the lesson by asking your students if they've ever followed a recipe. Potential guiding questions include: Have you ever followed a recipe? What sorts of measurements do you find in recipes?
Have students read the sample recipe you found on the chart.
Direct your students to identify the fractions.
Ask students to describe how the fractions are alike and different.
Pass around the measuring cup for students to examine.
Ask your students how they could use the same measuring cup to measure all of these different ingredients.
Explain that the measuring cup is one whole.

Explicit Instruction/Teacher modeling

(15 minutes)

Read through the recipe on your chart paper.
Choose one of the fractions from the recipe.
Demonstrate drawing a model of the fraction in a cup.
Label the parts of the fraction. Identify the numerator, or the number on top.
Explain how to break the cup into equal parts for each fraction.
Discuss why the size of the parts will change depending on the fraction. Reference how the measuring cup has many different fractions labeled on its side.
Repeat this step again using a fraction with a different denominator, or bottom number.

Guided Practice

(15 minutes)

Choose another fraction from the recipe. Together as a class, draw the model in the measuring cup.
Have your students draw the model on a measuring cup from the Measuring Cup worksheet.
Complete two more examples. Ask your students to work together to draw lines to break the cups into parts.

Independent working time

(20 minutes)

Show students the second recipe you chose on chart paper.
Instruct your students to draw a model on each measuring cup to represent each ingredient.
Have your students color in the parts of the fraction to correspond to the ingredient.
Ask your students to cut and glue the measuring cups onto one sheet of construction paper and label the corresponding fraction below.

Differentiation

Enrichment: Encourage students who need a challenge to add a “secret ingredient” of their choosing to the recipe. Students will need to label this fraction and draw a model on an additional measuring cup. Students may also try creating a model on their measuring cups using an ingredient with a mixed number measurement.
Support: For students in need of support, help them break the measuring cups into equal parts by folding and lining up the edges to make sure that they are equal. Alternatively, you may give the student a modified recipe that contains only fractions with like denominators.

Assessment

(5 minutes)

Make sure to circulate and address any misconceptions.
Collect construction paper with the measuring cups at the end of the lesson to review for mastery.

Review and closing

(5 minutes)

Have students share their models.
Facilitate a discussion about the importance of checking for accuracy on the models.
