Maths | My thinkbaords

For maths I did my thinkbaords. For the think baords I had to make q a number line on how I solved 38 + 50. I then also had to make a story problem. My story problem was : I have 108 dummies then siale came and took 73 of my dummies now how much dummies do I have left? Then we had to solve how I did 38 + 50 = 88. 
I solved this equation by by taking away the 8 and added the 30 and the 50 wich makes 80 then I add on the 8 so that makes 88. Then we practised simple addition.
