### PRODUCT DESCRIPTION

Division is generally more difficult for kids than multiplication. They often learn the facts from the multiplication point of view and are then taught that division is the inverse operation. Of course it is, but learning to factor will reinforce both multiplication and division AND be very useful in fractions and algebra as well. So, here are some cards that simply have products of simple multiplication facts on one side and the factors on the back. Why? Because students who know that 9 x 7 = 63 need to be able to see 63 and know instantly that 7 and 9 are among its factors. Making this connection explicit pulls everything together AND leads to further exploration into factors and divisibility.
The cards here are basically the opposite of multiplication flashcards (and somewhat different from division flashcards). The teacher (or another student) shows the product and the student names all factor pairs, which are listed on the back of the cards. The first set is products to 100 (facts through tens) and only includes the factors that appear on the multiplication table. [The second set -- available in my store also -- is products to 144 (facts through twelves).] Bonus points to kids that know that factors of 36, in addition to 1 x 36, 4 x 9 and 6 x 6, include 2 x 18!, Only exact products obtained by basic multiplication facts are represented in this set, so the only prime numbers presented are 2, 3, 5, 7. This is a good introduction to the concept of primes, but if you want to take your kids all the way into prime factorization, take a look at Discovering Divisibility Rules, then challenge your students with Finding Factor Cards All Numbers 0-144. From there, it's just a hop, skip and a jump to GCF, LCM and the world of fractions and an easier time with algebra!
