Today we made the X chart SOOOOO much easier. We did what we KNOW for a fact: 0, 1, 2, 5, 10, 11 in orange. Wow! Look how much of the chart is complete. Now we went down the middle with prime numbers. EX: 0 x 0, 1 x 1, 2 x 2. Then we highlighted the factor on bottom in yellow and crossed off its communicative property on top. EX: 3 x 6 = 18 so 6 x 3 = 18. We really only need to know less than half of the chart!
