Summer Math Suggestions

:

Subtracting facts:

• Strategy 1: Think Addition - Emphasize the relationship between addition and subtraction (fact families), instead of thinking of 13-5 as count 13, count off 5, count what’s left to get the answer (inefficient). Ask your child to think of this as 5 and what makes 13?

• Cover Up – Using any small objects, spread out any number (up to 18) and using a cup/cloth/hand to cover up a amount from 1-9. Ask your child to tell you how many are under your cup/cloth/hand.

• Strategy 2: One-Less and Two-Less Than Facts- Discuss the facts that are one-less and two-less. Students can make flash cards for these facts. Have them learn them in pairs. 9-7 and 9-2. You can create flashcards on

• Strategy 3:Doubles and Near-Doubles-With any worksheet of problems (that have a large number of doubles and near-doubles- these can be made online quickly,), have students circle the double subtraction facts (14-7), and in a different color circle the near doubles (15-7) and write the double that helps them next to it.

2 digit addition and subtraction:

• Use story problems like those on the sample page as a model. Students should use numbers, pictures, or words to show their work.

• Using only the number cards 1 (A) – 9 from a deck of cards. Turn over 2 cards for a 2-digit number, and another 2 cards for another 2-digit number and add.

• Using only the number cards 1 (A) – 9 from a deck of cards. Turn over 2 cards for a 2-digit number, and another 2 cards for another 2-digit number and subtract the smaller from the larger.

• Ask your child to create his/her own story problems and solve.

• Create your own worksheets or play games online with

Multiplication and Division facts:

• Always have your child learn his/her multiplication and division facts together (Ex: 3 x 4, 4 x 3, 12 ÷ 3, 12 ÷ 4)

• Using the array cards. Deal all the cards out to each of 2 players. Each player turns over the top card and states the product. The player with the larger product takes both cards.

• Multiplication Pairs (use the array cards). Spread all the array cards out on a table, either side up. This can be played in pairs, or alone. Point to a card, if the product is showing, say the fact that is shown in the shape. If the fact is shown, say the product. Turn the card over, if it’s correct, then you can take the card.

• Create multiplication and division riddles. Using any fact, like 36 ÷ 6, make a picture riddle to help solve this fact. (A picture of 36 balloons grouped into 6 groups).

• Use your array cards as flash cards. Show the fact side, and say the product. Or, create your own flashcards on
