Doubling and halving DLO

In Te Ngahere we have been learning to double and halving ( multiplication ) in maths. I think I did well because I was able to answer it the first time and not have to rub it out and try it again. I enjoyed the word problem because it set a harder equation for me. One of them ( word problem ) was 4222 x 5 = 21110. I think the next time we do this that I will be able to finish one whole sheet of math in one day so the next day I can do the next sheet.
