Obtain materials Obtain the Materials
  • Dice.  Two per child.
  • Yahtzee playing card [When the child rolls the 2 die, the sum of the 2 die is then crossed off on the card.  They keep going until they have crossed out all the numbers.  If they have a number crossed off and they roll that number again, they simply roll again.
























Note: Small parts create a choking hazard for children. Make sure that all materials you choose to use for an activity or lesson with children meet safety requirements. Small parts are not appropriate for children who are 5 years of age or younger.

Introduce the activity Introduce the Activity
  1. Explain that today we will all be using dice to practice addition.  Start by asking if anyone can explain what addition is. 
  2. Reinforce the definition of addition by stating that, “Addition is the joining of 2 or more numbers to get one number called the sum.”
  3. Introduce the game, Yahtzee and explain the goal of the game. 
  4. Model how to play the game. 
Engage the children Engage the Children
  1. Hand out game cards and dice.
  2. Model how to use the dice properly.  Encourage small rolls that stay on the table. It is important to model proper dice rolling to avoid dice flying everywhere and children spending more time retrieving dice than playing the game.

Additional Extensions

  • Use 3 dice and change the numbers on the card to 3 – 18.
Encourage vocabulary Encourage Vocabulary
  • Add – Increase in amount or number (e.g., "What number do you get when you add 3 and 4?")
  • Equal – To be the same in number or amount (e.g., "3 plus 4 is equal to 7.")
  • Plus – The addition of (e.g., "Explain that plus is another word used when we are adding one number to another, such as 3 plus 4 is 7.")

Supporting Children at Different Levels

Toddlers   Pre-K

Toddlers may:

  • Still be working on number recognition.
Vertical line

Pre-K Children may:

  • Be adding 2-digit numbers, 1 through 6 with ease.

Home child care providers may:

  • Rework the Yahtzee board to contain numbers 1 – 6 and have the children use only 1 die, crossing off the numbers as they roll them.


Home child care providers may:

  • Add 3 dice and modify the Yahtzee card to include numbers 3 thru 18.  They will learn the hard way how hard it is to roll a 3 or 18!

Outdoor connections Outdoor Connections
  • This game can be played like a Red Rover game.  Have an even amount of children line up in two lines facing one another.  Assign each child a number 1 to 12.  Call out two numbers (the 2 numbers that would have been rolled on the dice) and the sum or the difference of that number is the number that runs across the space and tries to break through the other team's chained line.  It is up to the children to figure out the difference or the sum of the two numbers called. If the child breaks through the line, he or she takes a child for their team.  If the child does not break through the line, he or she joins the opposite team.
