Greatest Common Factor – Mini Book

Learn different strategies to find the greatest common factor with this mini-book.

Let’s Learn About GCF (Greatest Common Factor)

What exactly does the term GCF mean? When determining the greatest common factor, this essentially refers to the largest number that can divide evenly into 2 or more numbers. The GCF is used with other math skills, such as simplifying fractions

Teach Starter has created a mini book that you can use with your students when learning about this important math concept. This download comes in 2 different versions. One version is completed, and the other has blanks for the students to fill in. Students will complete practice problems at the end of the mini-book.

The fill-in-the-blank version can be completed as a class with teacher guidance step by step. The completed version can be used for students who receive a copy of class notes and for absent students who missed the fill-in-the-blank lesson. Students cut the full-size pages in half to make 10 half-size pages. They can color all of the pages as much as the teacher would like. Then, staple the book on the left side and keep it as a reference. They could also be attached by hole punching the corner of each page and putting in a ring.

The goal of this resource is to provide students with a set of notes about GCF to use as a reference throughout the unit.

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 mini-book 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, check out these suggestions for keeping students on track with the concepts: 

🆘 Support Struggling Students

If there are students who need additional support, provide a multiplication chart and calculator. Students can also work in a one-on-one setting or with a peer tutor. 

➕ Challenge Fast Finishers

Ask students needing a challenge to create a tutorial video or poster that teaches the strategy they prefer for determining GCF. The teacher could challenge students to find the two largest numbers less than 100 that have a GCF of 1.
