Activity #1: Practice skip counting by memorizing the cards. (Skip counting can help us understand multiplication because it helps us count in equal groups to reach a number, like counting ten groups of two to get to 20)
Activity #2: Practice skip counting without the cards. Have a family member or friend, check the cards to see if your answer is correct.
Activity #3: Write out your multiplication facts on a sheet of paper. (For Example: “2 x 7 = 14”)
Activity #4: Skip count backwards.
Activity #5: Close your eyes and place your finger on a number. Depending on where you placed your finger, repeat the multiplication problem that equals that number. (For example: If I am on the NUMBER TWO CARD and my finger lands on “16”, I will quickly say “2 x 8.”
Activity #6: Practice multiplying one digit whole numbers by multiples of 10. Just add a zero. (For example: On the TWO CARD “2 x 3= 6” and if I add a zero “20 x 3 = 60”)
**Parents please know it is not limited to this, if you have any other activities to practice multiplication please feel free to use.

If you dont have any numbered cards - Step 1: Use a marker to print numbers from 1 to 12 (one on each card -- and write BIG). You can use the same number more than once. This will make things more fun as you play the game. Decorate the backs of the cards, if you'd like.
Step 2: Deal out all the cards to the players until all the cards have been distributed evenly. Each person makes a pile of his or her cards.
Step 3: Each person holds the pile in their hand face down. Each player draws from the top of his pile and lays a card out, face up, on the table.
Step 4: The first person to yell out the correct PRODUCT(x) or SUM(+) of the numbers on the cards wins that round of play and takes the cards.
Step 5: The game continues until there are no more cards to flip. The person with the most cards at the end, wins the game.
