Today was another "show what you know" kind of day! We have a decimal test tomorrow, so we are in review mode. Today we revisited PEMDAS and simplified numeric expressions using addition and subtraction of decimals.
In order to practice PEMDAS with addition and subtraction of decimals, I had to create some numeric expressions specifically for the topic. To review with my classes we simplified one together. To view the instructions to today's activity, please watch: PEMDAS with Addition and Subtraction of Decimals.
The sixth, and final, problem I asked the students to solve, had a writing component. I asked them to tell me the first step to solving the expression, explain their reasoning, and then simplify the expression.
