Math Ideas for 3rd Grade

Use popcorn to solve multiplication problems by creating arrays. 3 X 7 would look like:

X X X X X X X
X X X X X X X
X X X X X X X

Use popcorn and bowls to make multiplication problems such as 4 bowls with 8 kernels in each bowl. Have your child write the multiplication sentence 4 X 8 = and solve.

Have them create other problems. Practice addition facts by rolling two dice and adding the numbers. Progress to throwing three dice and adding them. You can set a total, such as 50, and whoever reaches it first wins.

Play the "What's My Rule?" game. Tell your child to think of a rule for you to guess (and visa versa) such as "add four" or "multiply by two". Then give him/her a number and they use their rule to give the answer. Do this several times and then decide what your child's rule is. Example: Give your child the number 5, they answer 9. Give the number 11, they answer 15. The rule is add four. Or, give the number 3, they answer 6. Give the number 8, they answer 16. The rule is multiply by two.

Create real life problems such as: If each person has two slices of bread how many slices will you need for 4 people? If one ant has six legs, how many legs do 4 ants have? Have them use numbers sentences, pictures, and/or items like toothpicks to represent the bread etc.
