Determine the factors of numbers less than 100 with these interactive slides.
What Are Factor Pairs?
Factor pairs are pairs of numbers that, when multiplied together, equal a given number. For example, the factor pairs of 12 are (1, 12), (2, 6), and (3, 4) because 1 x 12 = 12, 2 x 6 = 12, and 3 x 4 = 12.
A factor pair is different than a prime factorization, which breaks a number down into its prime factors. For example, the prime factorization of 12 is 22 × 3.
Knowing the factor pairs of a number can be useful in various math concepts, such as finding the greatest common factor (GCF) of numbers and solving problems involving fractions.
Teach Starter has created an interactive activity that will keep your students engaged while practicing this important 4th-grade math skill.
Tips for Differentiation + Scaffolding
A team of dedicated, experienced educators created this resource to support your math lessons.
In addition to individual student work time, use this activity to enhance learning through guided math groups, whole class lessons, or remote learning assignments.
If you have a mixture of above and below-level learners, we have a few suggestions for keeping students on track with these concepts:
🆘 Support Struggling Students
Have students use a multiplication chart or calculator to help determine factor pairs. Allow working in pairs or teaching during small groups.
➕ Challenge Fast Finishers
As an extension, have students research prime and composite numbers and practice identifying numbers based on their factors. Teachers can also modify the slides to include larger or more complex numbers.
