Activities to Teach Students to Multiply Two Binomials: Special Cases

Multiplying two binomials can be a challenging task for students, but there are some special cases that can make the process easier to understand. By using creative activities, you can teach your students how to multiply two binomials without difficulty.

Here are some activities that can help students understand how to multiply two binomials using special cases:

1. The “FOIL” Method

FOIL is an acronym for First, Outer, Inner, and Last, which represents the order in which students multiply two binomials. The FOIL method is one of the most common ways for students to multiply two binomials. In this activity, write four cards with each letter of the acronym on a separate card. Shuffle the cards and ask the students to place them in order and explain what each letter stands for. Then, provide them with two binomials and guide them through the FOIL process.

2. Perfect Squares

When students multiply a binomial by itself, it results in a perfect square. You can create an activity by providing students with a list of perfect squares and asking them to identify patterns they see in the numbers. Then, give them a binomial and ask them to square it themselves. Have them explain their thought process to the class.

3. Difference of Squares

The difference of squares is a special case that can help students learn how to multiply binomials. In this activity, provide the students with a binomial that is the difference of two perfect squares and ask them to use their knowledge of properties of squares to solve the equation. Then, provide them with a set of examples and ask them to identify the difference of squares, as well as discuss the pattern they see.

4. Factor Trees

Factor trees are useful tools for breaking down more complex equations. Use the factor trees to scaffold students’ understanding of how to break down equations. Start with numbers and then move onto binomials.

5. Real World Applications

Teach students to see how binomials can be applied in real-world situations, such as with a rectangular fence with sides represented by binomials. Have them use algebraic equations to determine how to calculate the area of the fence with binomials and then have them apply that equation to calculate the area of several different-sized rectangular fences.

Multiplying binomials can seem daunting, but by breaking it down into special cases and providing engaging activities, students can learn to master this concept with ease.
