Each Triangle Flash Card displays a family of facts, emphasizing the relationship between multiplication and division. This allows students to learn four facts on each side of the card--two multiplication and two division. For example a card with the numbers 8, 3 and 24 allow students to learn the facts: 8x3=24, 3x8=24, 24/8=3, 24/3=8. To use, cover the top number to practice multiplication or cover one of the bottom corners to practice division--or look at the whole card to see how all the numbers are connected. One side of each card features a more demanding family of facts while the opposite side features an easier one, allowing groups or individuals to practice at different levels with the same cards. Students will gain efficiency in memorizing. Includes 20 flash cards with instructions.
