- Solve Steps
- Word Problems
- Draw – picture, graph, table
- Known- from inside and outside the problem
- Unknown – what are you being asked to find
- Relationship – between known and unknown
- Solve
- Answer: Does it make sense? Plug it back in

- Solve Steps
- Use GEMDAS - work one side then the other
- Isolate the variable - when there is nothing left to do on either side
- Use one variable to solve for the other(s) - for a system

- Solve Steps
- Read and write down the problem
- Ask yourself - What do I do next?
