Engage your students' knowledge of expressing the prime factorization of numbers with this fun activity. I have..., who has... can be used as an unit opener, summary activity, or review day fun!
*The prime factorization is expressed in expanded form not exponential form.
*For prime numbers, the prime factorization is expressed as that number.
Numbers used in activity: 3, 4, 7, 8, 9, 10, 12, 15, 16, 18, 21, 24, 28, 30, 31, 34, 40, 49, 50, 75
Print on colored pages, card stock, or laminate
Print an additional copy for your reference during the game
Store cards in a labeled zip-locked bag to keep for future lessons
If the wrong “I have” statement is read, make the student who had the “who has” statement re-read their “who has” statement
Time each round (I use my phone) and make it a class-to-class competition (students LOVE this!!!)
Fabulous review day activity
Make students switch cards between rounds
Start with a different student and card each time
If there are more cards then students, give some students an additional card
I max out at 2 rounds a class (they will beg for more!!!)
