This match covers words problems that involve finding the Greatest Common Factor (GCF) and the Least Common Multiple (LCM). Students often struggle with knowing the difference between these two skills, especially with word problems. This mixed practice allows them to practice both skills, while also having to differentiate between the two. First, students will cut apart the different strips and sort the word problems into the GCF or LCM column (they will use the tops of the page as their sorting headers) to ensure that they know the difference. Then, they will go back and match each of the 6 different word problems with the correct answer in order to practice this skill. This is an excellent self-checking activity that allows students to practice these important skills. They love finding a match and find great relief when they get one of the answers. This is a flexible activity that could be used in partners, tables, or individuals. It can serve as practice, a warm up, homework, or even a formative quiz. The possibilities are endless.
