Today PJ and I started on the topic of solving equations using inverse operations. We went outside and used chalk on the tennis court. I wrote out problems like x+1=5 and asked PJ to guess what the value of x is. He answered 4 and I asked him to explain to me why. Then I showed him how to do the problem by doing inverse operations. I asked him "What is the opposite of addition?" He answered subtraction. I showed him that if we subtract 1 on both sides, it would cancel on the left side and we could simplify the 5-1 to 4. We practiced a few of those problem types together.
