Fraction Frenzy: Exploring Addition

Learning Objective

At the end of the lesson, you will be able to add fractions with different denominators.

What do you already know about adding fractions?

Understanding Fractions

Fractions represent a part of a whole. The top number is called the numerator, and the bottom number is called the denominator.

Like Denominators

When adding fractions with like denominators, simply add the numerators and keep the denominator the same.

Different Denominators

To add fractions with different denominators, we need to find a common denominator. This is the least common multiple (LCM) of the denominators.

Finding the Common Denominator

To find the common denominator, we can multiply the denominators together or use prime factorization.

Adding Fractions with Different Denominators

Once we have a common denominator, we can add the fractions by adding the numerators and keeping the denominator the same.

Differentiated Tasks: Level 1

Solve the following addition problems: 1/4 + 1/4, 2/5 + 2/5, 3/6 + 3/6

Differentiated Tasks: Level 2

Solve the following addition problems: 1/3 + 1/4, 2/5 + 3/4, 5/6 + 1/2

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
