Yellow and blue make green!
When students realize they only need to learn HALF of the Multiplication Table, they begin to believe that learning these basic facts up to the 12's is doable. Use the colors on this Multiplication Table to help students see that if they know the yellow basic facts, they also know the blue basic facts. Then point there is only one line of green where the yellow and blue meet, which is where they will find the doubles.
The colors also aid students to use the chart for division!
