## Math

We use the Envisions Math program.

Throughout the year, the students will bring home sets of addition and subtraction flash cards. (The students will have another set here at school, so there is no need to return the cards to school). It is important for students to know these facts. Higher math is dependent on the ability of students to recall the answers to facts quickly and accurately. Even though we will practice the facts at school, it would be beneficial for your child to practice with the fact cards at home, too, until they can say the answers automatically.

Doubles facts - ex. 4+4. 3+3

Adding 1 facts - ex. 5+1, 7+1 (say bigger number and count one more)

Adding 2 facts - ex. 4+2, 2+8 (say the bigger number and count two more)

Subtracting 1 facts - ex. 9-1, 3-1 (say the bigger number and count back one)

Subtracting 2 facts - ex. 7-2, 6-2 (say the bigger number and count back two)

Adding 0 facts - ex. 8+0, 4+0

Subtracting 0 (also known as subtracting none) ex. 4-0, 2-0,

Subtracting a number from itself (also known as subtracting all) ex. 9-9, 7-7

Adding to 10 facts - (facts with 10 for an answer) ex. 6+4, 3+7, 9+1

Subtracting from 10 facts - (facts that start with 10 before taking away) ex. 10-5, 10-4 (They are related to the addition to 10 facts. So if

you know the adding to 10 facts, it will help you with the subtracting from 10 facts.)

Adding 9 facts (these are facts that add a number to 9) ex. 7+9, 9+5, 8+9 (use adding 10 to help to help solve. So...9+5 think

10+5 is 15. 9 is one less than 10, 9+5 would be one less than 15 or 14.

Doubles plus one facts - ex. 7+8, 5+6. They addends are side by side on the number line. To solve, Take the smaller number, double it and

add 1. So...5+6 think...5+5=10, one more would be 11. So 5+6=11)

There is a rap we say to help remember the doubles facts. It is:

It's the doubles, baby, let's go, let's go!

It's the doubles, baby and we start with zero!

0+0=0 Oh!

1+1=2 Ooo!

3+3=6 Kicks!

4+4=8. That's great!

5+5=10. Again!

6+6=12 That's swell!

7+7=14. Let's lean!

8+8=16. That's keen!

9+9=18. Jelly bean!

10+10=20. That's plenty!

__Timed Tests__

It is a Washington school-wide goal to pass grade-level facts. The goal for first grade is to pass the

addition to 10 facts with 100% accuracy. Every Wednesday students take a math fact timed test.

It consists of 25 problems to be completed in two minutes or less. It is the goal for students to improve in speed and accuracy until reaching 100% on the test. Reaching 100% on three tests constitutes mastery and the student can move on to the next level of timed test.
