Practice Problems
Try them, get help one step at a time, then print how it went.
Practice: try it, then get help one step at a time
Checking points, graphing to solve, and the limit of graphing. Hint gives a nudge, Show next step shows one worked step at a time, Reveal answer checks, and Hide help / start over clears the card.
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.
Exit ticket
On paper or an index card. Use the math word and the plain-English word.
- What is a solution of a system of equations?
- Is (1, 4) a solution of y = 3x + 1 and y = −x + 5?
- Solve by graphing, in words: y = x + 2 and y = −x + 4.
- Why is graphing not always enough?
Check your exit ticket
- A point that makes every equation in the system true; on a graph, where the lines cross.
- 3 + 1 = 4 true; −1 + 5 = 4 true. Yes.
- Cross at (1, 3). Check: 1 + 2 = 3, −1 + 4 = 3.
- A crossing that is not on a grid corner cannot be read exactly; algebra gives the exact point.
