### 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 (through twelves) 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. Bonus points to kids that know that factors of 96, in addition to 1 x 96 and 8 x 12 also include 2 x 48 and 3 x 32 (but those aren't listed on the back! Only exact products obtained by basic multiplication facts are represented in this set, so the only prime numbers presented are 2, 3, 5, 7 and 11. This is a good introduction to the concept of primes, but if you want to take your kids all the way into prime factorization (especially the one who came up with 3 x 32!), 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!
PRINT 2-SIDED ON CARD STOCK - Instructions for doing so are on page 1. Fronts are blue, so print in color if you have the 10 x 10 set and want to be able to tell them apart.
