Basic Facts

This week for addition I got 100 right out of 100 and my time was 6:55

This week for subtraction I got right out of 100 and my time was 8:27

My goal is to be fast and accurate.

This week the maths strategy I have learned is:

1. using arrays to solve x problems

2. using my 5 x to solve 6, 7, 8, 9 x problems

3. using compensation to solve x problems

4. using compensation and place value to solve x problems

Here is an example of how to use it:

             x    3     x    4

1. 4x3, 5x4      000        11111        

                4    000    5  11111

                      000        11111

                      000        11111

2. 6x6, 8x7      

3. 8x9, 7x8

4. 5x19, 7x28
