Same Amount, New Name
Two bars with different cuts can hold the very same amount. Find the bar that lines up, then let the machine give it its new name.
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.
Watching one first is a strong way to start.
The machine does one thing: it multiplies the top and the bottom by the same number. These striped drawings are called fraction bars — make yours agree with the target.
Shade the second bar to show the same amount, then write the new name on the lines.
- 11/2= /
- 21/3= /
- 33/4= /
- 41/2= /
- 52/5= /
- 62/3= /
- 71/4= /
- 84/5= /
There is no right answer here. It only tells your teacher where to start next time.
You matched all eight.
Two fractions that name the same amount are called equivalent fractions. Multiply the top and the bottom by the same number and the amount never moves — only the name changes. 1/2, 2/4, 3/6: three names, one amount.
The stretch is a choice. Taking it — or leaving it for another day — are both strong moves.
One tap sends one row — how many you matched, the hints you used, your confidence, and the name you type. Nothing else ever leaves.
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 matched with no hints; supported means matched after a hint. Both are real evidence and neither is a grade.

Send the probe row to the class Sheet. One row per tap — there is no un-send, and a second tap makes a second row.
Every item pairs a fraction with its ×2 or ×3 name, denominators no bigger than 10. Set 2 and Set 3 are the same eight skills with different numbers, so the same student can be probed three weeks running without being measured on memory.
