Math Fluency 

Children will be exposed to a variety of addition and subtraction word problems in third grade. If your child is having trouble solving problems, encourage him to visualize what is going on with the problem. Identifying important information in the problem can help also.

example, Mrs. Smith has 48 stickers. She needs to share them equally with 8 students. How many stickers will each student receive? Student could draw a picture like the one below to solve and represent using an equation such as 48 8=?

Find the area of rectangles. Third graders will be finding the area of rectangles using a variety of strategies. Before learning the formula of length multiplied by width, they will be discovering what a “unit square” is and use this information to figure out how many “unit squares” will be  in a rectangular area. Their experiences will lead to them uncovering the idea that you can multiply length times width to find the area. Students will also solving real world problems involving area. 

Find the perimeter of shapes. Third graders will be learning to find the perimeter of shapes by adding all the sides together. Students may also have to find the length of an unknown side by using what is known about perimeter. For example, if a square has a perimeter of 20 inches, what is the length of one side?

Solve real world problems: For example, Mr. Jones wanted to build a fence around your backyard with the length of 20 feet and width of 10 feet. How much fencing do Mr. Jones needs to purchase?

Math Resources and Ideas for Families Online Activities to Try

Activities to Try at Home 

Use flashcards to practice multiplication and division facts. Stores such as Dollar Tree and Walmart sell premade sets or you can make your own using index cards.



Practice multiplication and division by using paper plates and counters (cereal, pennies, buttons, dry beans, etc. work well). For example, if the problem is 5 x 6, use 5 plates and put 6 counters on each. Have your child determine the product (30). For division, ask your child to count out a certain number of counters and then share it equally on the plates. For 459, have your child count out 45 counters and then divide it equally on 9 plates.



Incorporate division story problems into reallife situations. For example, if there are 8 pieces of pizza and there are 4 people eating, how many pieces will each person receive? You may even let your child physically act out the problem such as allowing the child to pass out the pizza to see each person would get 2 slices.



Share with your child how you use multiplication and division in your daily life. For example, if you are at the grocery store be explicit and say to your child, “The cereal is $3 a box. I need 3 boxes so I use multiplication to figure out quickly how much it will cost. $3 times 3 equals $9.”
