These addition and multiplication cards can be used as flashcards but can also be displayed in the hallway as Interactive Boards. Display the cards in rows with each set of facts in a different color. Print the attached blank addition and/or multiplication charts on large poster size paper. Once laminated, the blank charts can be filled out and reused for repeated practice. The students can use the cards to help them learn to fill in a blank addition and/or multiplication chart as a study tool.
