Practice finding greatest common factors with this activity.
Each student or student pair will get a set of 30 number pairs and a sorting chart. Students find the GCF of each pair of numbers. Then they arrange them on their chart. Greatest common factors range from 1 – 30. A few of the given numbers are over 100 to provide a little challenge!
You can also save time by having students write their answers on the chart instead of cutting and pasting.
This activity is great for partners!
