Writing Word Problems

LI:To choose addition or subtraction to solve word problems
I learnt to write addition and subtraction word problems. I also learnt that the word problems have to make sense. I had to write 10 of them that was subtraction or addition. We could change the numbers, but the numbers had to be 2 digit, 3 digit and 4 digit.
I learnt it by writing the word problems then figuring the answer out. We have to tell how we worked it out. We either had to do 1 or 2 ways of how we did it. I did 1 way because it would be the first thing that pops in my head.
