FRACTIONS: ADDING, SUBTRACTING, MULTIPLYING, AND DIVIDING
Throughout this site, you will find websites, games and activities to help strengthen your child's knowledge about fractions. Spending time each day to practice adding, subtracting, multiplying and dividing fractions can improve your child's fraction fluency. Encourage your child to spend time working on these educational activities either with a parent, guardian or on their own time.

- A fun activity to try with your child is to play the common denominator war. Finding the least common denominator of two fractions is one of the basic skills needed to work with fractions. You can find the common denominator of two fractions by finding the smallest number that is a multiple of both of them (lowest common multiple). This activity will give children plenty of practice in figuring out the lowest common multiple of two numbers.
- What You Need:
- Index cards
- Permanent marker
What You Do:- Write numbers on at least 20 index cards, making sure that most of the numbers are not prime. For example, you might choose numbers such as 8 (which has the factors 2 and 4) or 9 (which has 3 as a factor) more often than 7 or 11, which are both prime. Most of the numbers should be between 1 and 20, with a few larger ones that have a lot of factors (e.g., 20, 24, 30).
- Divide the pile of index cards in half into two smaller piles, and give each player one of these smaller piles.
- Both players call out “1, 2, 3…war!” and simultaneously turn over the top card in their piles and place it between them.
- The goal: as quickly as each player can, calculate the lowest common multiple of the numbers on the two cards, and call it out.
- The first player to call out the correct lowest common multiple wins the round and gets to add both of the cards to the bottom of her pile. Repeat Steps 3 and 4 for the next round.
- The game ends when one player runs out of cards. The other player is the winner.

Another fun (and yummy) activity to try with your children is looking at a Hershey chocolate bar and breaking the chocolate into parts (which will be the fractions). There are 12 pieces of chocolate in a Hershey bar, but if you break off 3/12 of the pieces what fraction of the Hershey bar did you break off? The answer would be 1/4 of the total bar. Then, you could ask students to add these fractions together. For example, if I broke off 3 pieces and ate them, then I broke off another 3 pieces, what fraction of the Hershey bar is broken off and eaten? The answer would be 6/12 pieces or 1/2 of the total bar.
