Take me out to the ballgame
Baseball in math – yes! From a pitcher’s ERA to a hitter’s on-base percentage. Calculate some statistics about your favorite players!
- Batting Average = total hits/official at-bats
- On-base Percentage = hits + walks + hits by pitch/at-bats + walks + hits by pitch + sacrifice flies
- Stolen Base Percentage = stolen bases/total attempts
- Fielding Average = total putouts + assists/putouts + assists + errors
- Earned Run Average = earned runs * 9/innings pitched

Lego Fractions
In third grade math, students start learning fractions in earnest. Playing with LEGOs makes it fun! Kids draw cards and use colored bricks to represent the fraction shown.

Triple Dare
Each player gets three cards and privately determines the highest three-digit number they can make (you can use decimals or not, depending on age). Then, each player has a turn to stick with the cards they have, swap with one from the deck, or steal one of the other player’s. All players then lay down their best number to see who wins. See more at the link below.

Fraction Game: My Closest Neighbor
Players: two to four.
Equipment: two players need one deck of playing cards, three or four players need a double deck.
How to Play
Remove the jokers from your deck of playing cards. Each number card will represent its face value, aces count as one, and face cards as twelve.
Deal five cards to each player. Set the remainder of the deck face down in the middle of the table as a draw pile.
You will play four (or more) rounds:
- Closest to zero
- Closest to one
- Closest to 1/2
- Closest to two
- Closest to 3/4 (optional)
- Closest to 1/3 (optional)
In each round, players choose two cards from their hand to make a fraction that is as close as possible (but not equal) to the target number. Draw two cards to replenish your hand.
The player whose fraction is closest to the target collects all the cards played in that round. If there is a tie for closest fraction, the winners split the cards as evenly as they can, leaving any remaining cards on the table as a bonus for the winner of the next round.
After the last round, whoever has collected the most cards wins the game.

Declare a Fraction War
Students deal two cards, flips them to make a numerator and denominator, then determine whose fraction is the largest. The winner keeps all four cards, and play continues until the cards are gone.. Comparing fractions gets a little tricky, but if kids plot them on a fraction number line first, they’ll be practicing two skills at once.

Multiplying Dominoes
Eventually, kids will have to memorize multiplication facts, and this quick and easy domino game can help. Each player flips a domino and multiplies the two numbers. The one with the highest product gets both dominoes.

Divide and Conquer
Think Go Fish, but instead of matching pairs, the aim is to match two cards in which one can divide evenly into the other. For instance, 8 and 2 are a pair, since 8 ÷ 2 = 4.

How to Play Make a Buck
The object of this game is to be the first person to collect ten cards that exactly equal $1.00.
- This game is played using a complete deck of cards. In this game, Ace = $0.01, Two = $0.02, Three = $0.03, … Tens = $0.10, Jack = $0.11, Queen = $0.12 and King = $0.13.
- To begin, shuffle the deck and deal ten cards to each player.
- Players then take turns drawing and discarding one card at a time until the deck of cards is depleted or a player collects exactly $1.00.
- This means it will involve a bit of logic and problem solving to discern which cards to keep and which to discard, as well as thinking through possible ways to collect $1.00.
- The first player to collect ten cards that equal $1.00 wins that round and earns 1 point.
- If no one has $1.00 after the deck is depleted, the person closest (without going over) earns .5 of a point.
The player with the most points at the end of ten rounds wins!
