Multiplying Fractions: Parts of Parts

Learning Objectives

• Find a fraction of a whole number.
• Multiply a fraction by a fraction using area models and the rule, and simplify the answer.
• Solve real-life problems that involve multiplying fractions.

How to Use This Resource

• Fold a piece of paper in half, then shade 3/4 of one half, to show 1/2 × 3/4.
• Teach the area model and the rule with the slides, then use worksheet activities 1 to 6.
• Use the quiz to check learning and send the recipe homework home.

Classroom Activity Ideas

• Paper folding: fold paper to model 1/2 × 1/3 and 2/3 × 1/2 and compare the shaded parts.
• Recipe scaling: halve a simple recipe and work out the new amounts.
• Fraction of a group: find 2/5 of the class, 3/4 of the crayons in a box and 1/3 of the books on a shelf.

Differentiation

Support: start with unit fractions of whole numbers and use counters and area models. Challenge: multiply mixed numbers by converting them to improper fractions first.

Assessment

Activity 1 and the quiz check the multiplication rule; activities 2 to 6 check fractions of whole numbers, models and problems. Use the rubric for activity 6.

Teacher Tips

Say "of" when you see ×: 1/2 × 3/4 means half of three quarters. It helps students predict that the answer will be smaller.
