Addition flash cards including sums from 1 to 10. One side of each card shows the problem and the other side shows the problem with answer. Simply print the file 2-sided on a light colored, heavy weight paper such as cardstock (laminate for increased durability if desired) and cut out the cards. Bright color coding and graphics make it easier for children to identify patterns in addition. 25 cards (front and back) on 8 pages are included with this item.
