Divide Whole Numbers by Unit Fractions Using Models

Learn to divide using delicious pizza slices and colorful fraction bars!

What Does It Mean to Divide by a Fraction?

Dividing by a fraction is like asking "how many parts fit into the whole?"
When we divide a whole number by a unit fraction (like ½ or ¼), we're finding out how many of those fraction pieces make up the whole number. Visual models help us see exactly what's happening!

How to Divide Using Models

1️⃣ Draw your whole number as complete shapes (like pizzas or bars)

2️⃣ Divide each whole into equal parts based on the denominator

3️⃣ Count all the parts to find your answer!

Let's Practice Together!

Example 1: Pizza Party!

If you have 2 whole pizzas and want to divide them into ¼ slices, how many slices will you have?

Each pizza divided into ¼ slices

Example 2: Cookie Jar Challenge

You have 3 cookies to share with friends. If each friend gets ⅓ of a cookie, how many friends can you serve?

How many ⅓ pieces are in 3 cookies?

Parent Tips 🌟

  • Use real food - Cut apples, pizzas, or sandwiches to show fraction division in action!
  • Color coding helps - Have your child use different colors for each whole when drawing models.
  • Relate to multiplication - Show that dividing by ½ is the same as multiplying by 2 - this helps build number sense!
