Practice Problems
Try them, get help one step at a time, then print how it went.
Practice: explain the reasoning
Explain in words, name lurking variables, and defend a real cause. Hint gives a nudge, Show next step shows one worked step at a time, Reveal answer shows a model answer to compare with, and Hide help / start over clears the card. For these, decide for yourself how close your answer is to the model.
My results
Finished the practice? Print a page that shows each question, what you typed or chose, the correct answer, and how it went. Good for showing a teacher or keeping in a folder.
