How many times will it land on 1?

Predict how often face 1 appears when you roll one die 100 times. Record every landing, export the raw results, and use Google Sheets to compare landed on 1 with did not land on 1.

The method, in this experiment

Seven moves. One dataset.

Observe + askHow often will face 1 appear?
PredictFor a fair die, expect about 100 ÷ faces landings on 1.
PlanChange the die type; keep the 100-roll count and recording rule consistent.
TestRoll physically and write down every landing. No deleting “weird” rolls.
AnalyzeIn Google Sheets, organize 1 and not 1, then make a bar graph plus a circle graph.
ArgueCompare your number of 1s with the expected count using CER.
CommunicateShare the sheet with teammates, compare matching dice, and name the next test.

Fair test rule: use the same rolling surface, release style, die, and counting rule for all 100 rolls. If you change dice, start a new dataset.

01 · prediction before data

With a fair d6, face 1 should land about 16.7 times in 100 rolls. How many 1s do you predict?

Your roll controls unlock after you record a prediction.

Roll the physical die

prediction locked? not yet

Use the die in your hand. Enter one face at a time, or tap a face button after each roll. The raw sequence is your evidence.

03 · export + analyze

Take your raw data to Google Sheets

finish 100 rolls first

The export contains only your raw record: the roll number and the number that landed. Use the sheet to count the 1s, then build the 1-versus-not-1 frequency table, bar graph, and circle graph. The browser does not upload or store student results.

04 · next question

What changes if the die changes? Repeat Experiment 1 with a d4, d8, or d20. Compare the percentage of rolls that landed on 1, not only the raw count. A d20 has more faces, so its expected number of 1s is smaller. Share your sheet with teammates and compare matching die types.
