# Activities to Teach Students to Multiply Fractions and Whole Numbers: Sorting

When it comes to teaching students how to multiply fractions and whole numbers, educators have a variety of techniques and activities at their disposal. One particularly effective activity is sorting.

Sorting involves presenting students with a set of cards or objects and asking them to group them into categories based on certain criteria. In the context of teaching multiplication of fractions and whole numbers, sorting can help students understand the relationships between the two types of numbers and develop strategies for solving problems.

Here are a few examples of sorting activities that can be used to teach multiplication of fractions and whole numbers:

1. Mixed Numbers vs. Improper Fractions

To help students understand the difference between mixed numbers and improper fractions, create a set of cards with both types of numbers on them. Ask students to sort the cards into two piles: one for mixed numbers and one for improper fractions. This activity can help students visualize the relationship between whole numbers and proper fractions within mixed numbers, and develop a more intuitive understanding of the concept of multiplication.

2. Simple vs. Complex Problems

Create a set of word problems involving multiplication of fractions and whole numbers. Some problems should be simple, such as 3 x 1/2, while others should be more complex, such as 3/4 x 1/5. Ask students to sort the problems into two piles: one for simple problems and one for complex problems. This activity can help students develop the skills needed to tackle more challenging multiplication problems.

3. Multiplication by Whole Numbers vs. Multiplication by Fractions

Create a set of cards with multiplication problems involving both whole numbers and fractions, such as 5 x 1/2 and 2/3 x 4. Ask students to sort the cards into two piles: one for problems involving multiplication by whole numbers, and one for problems involving multiplication by fractions. This activity can help students understand the rules for multiplying fractions by whole numbers (keep the denominator the same, multiply the numerator) and develop strategies for tackling more complex problems involving multiplication of fractions.

4. Equivalent Fractions

Create a set of cards with equivalent fractions, such as 1/2 and 2/4. Ask students to sort the cards into groups based on their relationship to whole numbers. For example, one group might include fractions that are equivalent to whole numbers, such as 2/2 and 3/3, while another group might include fractions that are less than whole numbers, such as 1/2 and 1/3. This activity can help students understand how to use equivalent fractions to simplify multiplication problems and get rid of denominators that are not factors of the whole number being multiplied.

In conclusion, sorting activities can be an effective way to teach students how to multiply fractions and whole numbers. By presenting students with a set of cards or objects and asking them to group them into categories based on certain criteria, educators can help students develop a more intuitive understanding of the relationships between different types of numbers and develop strategies for solving multiplication problems.
