Description
Students can match composite numbers with their prime factorization and then use QR codes to see if they are correct.
Print and laminate the cards. Then cut them in half.
As students work, they match the QR codes and then scan. If is scans, the correct answer will show. If it does not, nothing will scan.

This is a very engaging and fun activity for the students!
This was a wonderful resource. Thank You!
This is a fun idea, and the rigor was perfect for my average ability 6th graders. Our tablets did have difficulty scanning the split QR codes, so I did make a new set with the codes on only one side. I think it'd be more helpful for the QR code answer to show the prime factorization in exponents, rather than having the QR code display the product. In my standards, student start with the product, then find its factors--so I guess I think of it the other way around, with the prime factorization being the answer.
Great idea! Very creative! At first, I cut the cards down the middle of the QR code. My students had trouble lining up the cards directly to create a perfect match so that the cards would scan. I ended up making a new set where the entire QR code was on one half. Great idea though! Students enjoyed it!
thanks. Very useful.

CCSS6.NS.B.4
Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1–100 with a common factor as a multiple of a sum of two whole numbers with no common factor. For example, express 36 + 8 as 4 (9 + 2).
CCSS6.EE.A.1
Write and evaluate numerical expressions involving whole-number exponents.
