Home Activity: Multiplying Fractions

A fun 10-minute activity to do with your child!

Dear Family,

Your child is learning about multiplying fractions. The key rule is simple: multiply the top numbers (numerators) together, and multiply the bottom numbers (denominators) together. An important concept is that multiplying by a fraction less than 1 gives a SMALLER answer. This is an important skill for the Florida FAST test. Below are simple activities you can do at home to help your child succeed. No math expertise needed!

Activity 1: Paper Folding Magic 10 min

You'll Need:

  • A piece of paper
  • Colored pencils or markers (optional)

Fold the paper in half one way. Ask: "What fraction is each section?" (1/2)

Now fold it in thirds the other way. Ask: "How many sections do we have now?" (6) "Each section is what fraction?" (1/6)

Explain: "We just showed 1/2 x 1/3 = 1/6! When we folded in half and then in thirds, we created 6 equal pieces."

Try another: Fold in thirds first, then in fourths. Ask: "What is 1/3 x 1/4?" (1/12 - you'll have 12 sections!)

Key Phrase to Use:

"To multiply fractions, multiply the tops (numerators) and multiply the bottoms (denominators). No common denominators needed - it's simpler than adding fractions!"

Activity 2: Recipe Mathematician 5 min

You'll Need:

  • A recipe (any recipe with fractions)
  • Paper and pencil

Choose a recipe. Say: "This recipe calls for 3/4 cup of flour. What if we want to make only half the recipe?"

Set up the problem: "We need 1/2 of 3/4 cup. That means 1/2 x 3/4."

Calculate together: "1 x 3 = 3 for the top. 2 x 4 = 8 for the bottom. So we need 3/8 cup of flour."

Try more ingredients from the recipe using the same process!

Real-World Connection:

"Multiplying fractions is used all the time in cooking! When you want to make half a recipe or double it, you're multiplying fractions."

Activity 3: The Shrinking Game 5 min

You'll Need:

  • Paper and pencil

Ask: "What is 1/2 of 12?" (6) "Did it get bigger or smaller?" (Smaller!)

Now ask: "What is 1/2 of 1/2?" (1/4) "Is 1/4 bigger or smaller than 1/2?" (Smaller!)

Explain: "When you multiply by a fraction less than 1, you're taking a PART of something. A part is always smaller than the whole!"

Challenge: "Without calculating, will 3/4 x 5/6 be bigger or smaller than 3/4?" (Smaller - because we're taking 5/6 OF 3/4)

Important Concept:

"Multiplying by a fraction less than 1 gives a SMALLER answer. This is the opposite of what many kids expect! Think of it as taking a PIECE of something."

Questions to Ask Your Child

You're Making a Difference!

Just 10 minutes of practice at home can make a big impact on your child's confidence and success. Multiplying fractions is a skill they'll use in cooking, construction, and throughout their math education. Thank you for being part of their learning journey!

Para Familias Hispanohablantes:

Su hijo esta aprendiendo a multiplicar fracciones. La regla es simple: multiplica los numeradores (numeros de arriba) y multiplica los denominadores (numeros de abajo). Por ejemplo: 1/2 x 1/3 = 1/6 (1x1=1 arriba, 2x3=6 abajo). Un concepto importante: cuando multiplicas por una fraccion menor que 1, el resultado es MAS PEQUENO. Las actividades de arriba usan papel doblado y recetas para practicar. Gracias por apoyar el aprendizaje de su hijo!
