Kahoot
Three 6-question knowledge checks, and how to run them
Three quizzes sit at the three natural seams of the workshop: after the shape and vocabulary work, after the einsum and pseudoinverse stretch, and after the decompositions. Each sits right after the blocks that supply its content, while the material is still fresh, and before the next context switch — a break or a new Part — so it reinforces rather than interrupts.
Facilitators: import each spreadsheet into kahoot.it before the session. Create → Add question → Import → Import spreadsheet. Doing it live costs several minutes you do not have.
The three join links below still point at kahoot.it itself — which works, because students enter the PIN from your screen there. Once each quiz exists, paste its direct join URL into the url: field of _variables.yml and re-render: every link on this site, in both decks and in all twelve notebooks reads from that one file.
Quiz 1 — Tensor Vocabulary & Shapes
Vocabulario de tensores y formas
| Runs after | Section 04 — Reshape and transpose, before the first break |
| Covers | Sections 01, 03, 04 |
| Length | 6 questions, ~5 min including the podium |

Everyone has just used order, axis, shape, slice, fiber, variance, reshape and transpose — this is the moment those words are freshest. Two questions reach back into the exercises specifically: the NaN question is section 03’s zero-variance pixels, and the last one is section 04’s reshape-versus-transpose.
Quiz 2 — Einsum, Distance & the Pseudoinverse
Einsum, distancia y la pseudoinversa
| Runs after | Section 07 — Inverses and the pseudoinverse, before the recursion demo |
| Covers | Sections 06, 07 |
| Length | 6 questions, ~5 min |
| Import file | kahoot/kahoot_quiz_2_distance_pseudoinverse.xlsx |

Two questions here are ahead of the material. Quiz 2 asks about Euclidean distance and cosine similarity, which the handbook never defines directly. The bridge is section 06’s TODO 4 — the 1797×1797 digit similarity matrix built with one einsum. Say the two words out loud during that exercise, or expect the last two questions to land cold.
Quiz 3 — Convolution & Tensor Decompositions
Convolución y descomposiciones tensoriales
| Runs after | Section 10 — Tucker decomposition, immediately before the wrap-up |
| Covers | Sections 09, 10 |
| Length | 6 questions, ~5 min |
| Import file | kahoot/kahoot_quiz_3_convolution_decompositions.xlsx |
| Join link | https://kahoot.it/ |
Run it while the taxi-tensor rush-hour result is still on screen. Its final question names hour 18, so it must come after section 10’s TODO 6 — running it early gives the answer away. It doubles as a live rehearsal of the wrap-up’s own recap, so segue straight from the podium into the wrap-up.
Running them
- Budget 5 minutes each, including the podium. Groups want to see the leaderboard, and that is fine — it is the payoff.
- Do not import live. See the note at the top of this page.
- These add 15 minutes, taking the workshop from 180 to 195.
If you are running out of time
The handbook’s cutting order, in order:
- Quiz 2 — the least novel of the three; the pseudoinverse and distance get re-covered narratively in the wrap-up.
- TODO 4 of section 09 (true deconvolution — the most technically demanding).
- The RNN snippet in section 08.
- Question 5 of either group block.
- Quiz 1.
Never cut section 01’s Three Operations That Matter, section 10, or Quiz 3 — the last is the cheapest way to check whether Tucker and CP actually landed before students leave.
