| I understand this concept fully. I could explain and model the practice and word problems to someone else…AND I can apply the concept when setting up & solving the advanced higher order thinking/application word problems. | I understand this concept & feel confident completing the practice problems. Sometimes I make silly mistakes, but I know what I did wrong & could easily make corrections. I can set up & solve the average to higher level word problems. I’m not 100% confident setting up and solving some of the advanced higher order thinking problems on my own | I’m confused on this concept as I work through the practice problems. I’m not sure if my answers are right or wrong or how to make corrections because I’m not sure what I’m doing wrong. I’m definitely not comfortable solving or setting up even the basic real-life word or application problems without help | |
