Well done Tha Zin! You have done some great working out and you used division and multiplication strategies for the right questions. The working out for question 1,2,6 and 7 are perfect. For question 3 about the Moros, you can do this: 7x13 = 7x10 and 7x3. 7x10=70, 7x3= 21. 70+21=91. Did you see how I broke up the tens and the ones? How can you use the same strategy for question 4? (28x6)
