How do I know that's true?

There is no send button, no upload, no account, no sign-in. Your work is saved on this one computer so you can come back to it — and you can erase it whenever you want.

This page has no way to send anything. It saves your work in this browser's own storage on this machine. It loads nothing from the internet and sends nothing out, so there is no copy anywhere else — not with your teacher, not with the school, not with anyone.

This one is different from the Wednesday worksheets. Those are your own thinking and nobody reads them. This is math, and math is meant to be looked at together — your teacher may stand next to you and read this screen, and may write down how it went. Nothing travels on its own; a person has to be standing here.

Asking for a hint is not cheating. The hints are part of the lesson. Using them tells your teacher what to teach next, which is exactly what they are for.

If you share this computer, erase before you go. Anyone who uses this same browser profile could open the page and see your work. That is what the erase buttons are for, and using them is completely normal.

Mathematics · Activity 1

One-Step Equations

An equation is a balance. Whatever you do to one side, you do to the other — and you keep going until x is standing alone.

On this computer only

No score is kept. No points, no streak, no ranking — the only number anyone writes down is the one your teacher writes down, standing next to you.

Show me one first

This one is nobody's problem — it is only here to show the moves before you touch yours. Watching it costs nothing and is written down nowhere.

x + 4 = 9
Something is being done to x: 4 is added.
Undo it — − 4 from both sides.
x = 5.

Now problem 1 is yours. The hint button is there the whole time, and using it is part of the lesson.

  1. 1x + 7 = 12
  2. 2x + 9 = 16
  3. 3x − 4 = 11
  4. 4x − 8 = 5
  5. 53x = 21
  6. 66x = 42
  7. 7x/4 = 6
  8. 8x/5 = 3
  9. 9x + 14 = 9
  10. 102x = −14
How confident are you with these?

There is no right answer here. It only tells your teacher where to start next time.

For the teacher — this device only

One probe row, built from what happened on this screen. Nothing is sent anywhere — copy it into the Goal Builder yourself, or print this page. Independent means solved with no hints; supported means solved after a hint. Both are real evidence and neither is a grade.

Set 2 and Set 3 are the same ten skills with different numbers, so the same student can be probed three weeks running without being measured on memory.
