- We will simplify numerical expressions that do not involve exponents, including up to two levels of grouping.
- I will use GEMDAS to simplify numerical expressions that do not involve exponents.
So, now we will have all kinds of scheduling changes and loss of students for the next week and a half. It begins today with the practice of our "all school" musical. I will lose my 1st period music students, so I wanted to do something that was a review, but also something that was a little fun. I did not want to include a Fifth Grade Builder, as those students would not benefit from class time. I chose to review GEMDAS.
Number Sense
Number Sense
- Before beginning their "leaf", I needed my team to take a Number Sense practice test.
Think Through Math Benchmark
- Some students did not complete the benchmark yesterday, so before beginning their "leaf", these students had to complete the benchmark.
GEMDAS Leaf
As a student, I learned the order of operations using PEMDAS. However, brackets tended to confuse the issue because the "P" stands for "parentheses" and a bracket is not a parentheses to an elementary student. So, the mnemonic device has changed to GEMDAS. The "G" stands for "grouping symbols" which covers both parentheses and brackets.
I found a free download on Teachers Pay Teachers that is perfect for today:
This leaf has 24 problems that involve GEMDAS, but do not include the use of exponents. The answers are given, which helps students know they are on the right track, but also is a color code for coloring the leaf. I did include a response sheet on the back, so that I know that they did the work and got the correct answer and didn't just color.
This activity was not intended to be completed today. We worked for about 30 minutes on it and then we worked for about 30 minutes on Think Through Math.
