Cut up the numbers, operations, and grouping symbols and put them in an envelope with the answer to the problem on the outside of the envelope.
Students should use the contents of the envelope to find out how to use Order of Operations to get to the answers.
I staples my envelopes inside a file folder to keep it organized. I also printed the numbers, operations, and grouping symbols on pretty scrapbook paper and laminated them to keep them lasting longer.
Here's the directions that are included that I printed and glued onto the front of my file folder:
1. Take the contents of the first envelope out and spread them out on the table.
2. Given the answer, numbers, operations, and grouping symbols, arrange the pieces to make the correct expression.
3. Don’t forget to use the Order of Operations.
4. Record & check your work.
5. Do not start the next envelope until you have finished and cleaned up the previous one.
6. Continue until you have completed all the envelopes or time is called.
7. Make sure to clean up!
