Math Facts

This year we will be continuing to work on reviewing addition, subtraction, multiplication and division facts. Students will be working at their own pace learning sequential sets of facts. We will be reviewing specific strategies that will help them learn their facts. I will send home a sheet of new math facts each time they pass a test. Please have them orally practice (say the answers out loud) the facts on this sheet each evening. They will need to be able to say 18 correct answers in 1 minute in order to pass. When they bring a new sheet home you will know that they have passed the previous sheet. Here is the order of the facts that the students will be working on this year. Students will not have to work on addition or subtraction facts if they have shown they have mastered them. Addition, subtraction and multiplication will be a review of what they learned in 3rd grade. Multiplication and division strategies will be taught together as division is based on knowledge of multiplication facts.

Addition

Count on ones (+1)
Count on twos (+2)
Count on threes (+3)
Mixed count on facts (+1,+2,+3)
Doubles (2+2,3+3 ...9+9)
Doubles plus one (2+3, 3+4...8+9)
Doubles plus two(2+4, 3+5...7+9)
Make a ten (e.g. 7+4, 8+3, 9+5--this strategy helps students take an amount away from the smaller number to make the bigger number equal 10, then it is easy to add what remained of the smaller number to 10)
Use all addition strategies

Subtraction

Count back 1,2,3 (-1,-2,-3)
Count on 1,2,3 (e.g. 11-8, 10-7--start with the smaller number and count up to the bigger number to find the difference)
Doubles and near doubles (Use knowledge of addition doubles facts and doubles +1 and doubles +2 to find the answer to the corresponding subtraction fact)
Use addition (think of the corresponding addition fact to find the answer to the subtraction fact)
Mixed subtraction
