1. What About Those Math Facts!
Using a Strategy-Based Approach

2. GDS APPROACH
Children learn and retain math concepts, procedures, and facts best when they are led to understand what they are doing before any memory of facts or procedures is expected.

3. STRATEGIES FOR LEARNING BASIC FACTS--ADDITION
Doubles
6+6, 4+4…..
One More Than
Doubles +1
10 Sum +1
Easy 9’s
One less than +10
Make 10, add extras
Ones digit is one less
Last 4 Facts
7+5, 8+4, 8+5, 8+6
Count Ons
+1, +2, +3
Turnarounds
2+9 is the same as 9+2, then use the count-on strategy
Zero Facts
7+0, 0+7
10 Sums
6+4, 7+3….

4. ADDITION TABLE + 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
Easier Facts

Hard Facts

5. STRATEGIES FOR LEARNING BASIC FACTS--SUBTRACTION
Count Backs
-1, -2, -3
Subtraction Doubles
8-4, 6-3
Zero Facts
6-0, 6-6
10 Facts
Uses “10 sums” and the 10-frame
One More Than
10-8=2, so 11-8=3
9 Facts
If 13-10=3, then
13-9=4
Last 4 Facts
12-7, 12-8, 13-8, 14-8

6. This requires practice!!
BASIC FACTS MASTERY
The overriding goal is to raise the level of response until correct answers are given quickly (within 2 seconds) and consistently over time.
This requires practice!!

7. HOW YOU CAN HELP Keep sessions short (3 to 5 minutes)
Introduce only a few facts at a time, include some mastered facts
Call out facts at odd moments – like in the car
“Less is best, more often”
Five minutes a day is better than thirty minutes once a week
Set a timer for 3 to 5 minutes for your child to review flash cards on his own
Keep sessions positive; praise quality effort
Use a “Facts I Know” cross-out chart
