The Interior Mathematics

Activity 3 · Walk the Line. Walk it here, or print it and use a pencil — both count.

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 3

Walk the Line

Stand on the first number. The second number tells you two things — how far to walk, and which way. Where you stop is the answer.

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.

−2 + 6
Stand on −2.
Adding a positive walks right — 6 steps.
You stop on 4.

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

  1. 1−4 + 7 = −10−50510
  2. 23 + (−8) = −10−50510
  3. 3−5 + (−4) = −10−50510
  4. 46 + (−9) = −10−50510
  5. 5−7 + 7 = −10−50510
  6. 63 − 8 = −10−50510
  7. 7−2 − 5 = −10−50510
  8. 84 − (−3) = −10−50510
  9. 9−6 − (−9) = −10−50510
  10. 105 − 5 = −10−50510
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 walked with no hints; supported means walked after a hint. Both are real evidence and neither is a grade.

Items 1–5 add, 6–10 subtract, and two of them land on zero. 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.
