Practice skip counting and learning multiples with Factor House. Students use a set of jumbled up number cards in multiples of 2,3,4,5 or 6,7,8,9 and place them order from smallest to highest. The activity works and looks best when printed A3 size and laminated to last longer. I personally use this activity with year three students but is perfect for 7-10 year olds or anyone trying to master their multiplication tables. Depending on the student, it will take roughly 10-20 minutes to complete.
