Many children can add with counting procedures, such as counting out each set (e.g. a set of 3 and a set of 5 for 3 plus 5) before combining the set and counting the result to get the sum (e.g. eight). The challenge is helping them recognize and internalize the many valid strategies for adding two numbers together. For example, when adding 14 and 27:
• You can add the 10 and the 20 and then the 4 and 7 and then combine.
• You can add the 7 to 14, get 21, and then add the 20.
• You could take 6 from the 27, add it to the 14 for an even 20, and then add the remaining 21.
Playing these fun addition games with your child can deepen his or her relationship with addition and develop fluency with multiple ways of adding, while you spend quality time together!
Go Fish, With an Addition Twist!
This game adds another level of challenge to the classic game of Go Fish – the key here is to get as many pairs that add up to 10 as you can! You’ll need a deck of cards for the group as well as a piece of paper and pencil for each player. Please note that ace = 1; jack, queen and king = WILD cards, which means that they can be any number a player needs to make 10.
Variations of this math game:
For younger children, remove the jack, queen and king cards. Simply play with ace – 10 cards.
Try different sums near 10, such as 9, 11, or 12. You can also make Jack = 11, Queen = 12 and King = 13 and make 14 the pair goal.
For more than four children, play with multiple decks of cards, shuffled together.
For discussion: After playing this activity, you might want to ask your kids some questions such as:
• What did you think of the “wild” cards and how did assigning values to Jack, Queen and King change the game?
• What do you think of playing with more cards? What do you think of playing with fewer cards? Will it be less or more difficult to make 10? Why?
• How did changing the pair goal affect the game?
Your mission, should you choose to accept it, is to capture more prisoners than your opponent. To embark on this mission, you need a deck of cards for this two player math game. Please note that ace = 1; jack = 11; queen = 12; and king = 13.
Variations of this math game:
Advanced Addition War: Use three (or four) cards for each skirmish and add them together to find the greater sum.
Addition War with Allies: Call in the reinforcements! Each player can use his or her own deck of cards and pair up to play two on two. You can modify the rules in any of the following ways:
• Each player flips over two cards and finds the sum. The pair of cards that makes the greatest sum is presented to the other team. The team with the pair that makes the greatest sum wins all eight cards per skirmish. In case of ties, you can conduct battles in a 2-down-2-up battle pattern.
• Each player flips over two cards. Each team finds the sum of all four cards they’ve flipped over. The team whose cards have made the greater sum wins all eight cards per skirmish. In case of ties, you can conduct battles in a 4-down-4-up battle pattern.
Addition Boot Camp: For younger children, only use the cards from ace to five. As they become more confident in their mental arithmetic skills, you can reintroduce sixes, sevens, etc. back into the game.
For Discussion: Talk with your learner(s) after playing Addition War and get them thinking about how they can take ownership of the game and flex their creativity.
• What new rules would you include for the next round? Why do you think we should play with those rules?
• What rules can make this game more challenging? Why?
• What was your favorite version of War?
Motion Math: Hungry Fish, our addition and subtraction game for ages 4 to 44
You will need one iOS device: an iPad, iPhone or iPod Touch.
• How many different ways can you make a sum, using two bubbles? For example, what combinations could you use to make 7?
• If you could use more than two bubbles, how many ways can you make a 7? What about 8? For more advanced learners, if your goal were to create a sum of “n”, how many ways can you make it?
• Can you draw a picture of all of the bubbles you’d want for your fish, if your fish has a 35 on it? Bonus points if you email us your picture!
• Did you like the reef or the cave better and why?
