Formative assessment sounds formal, but at heart it is simple: find out what students understand while there is still time to do something about it. A test at the end of the unit tells you what happened. A quick check in the middle of a lesson tells you what to do next.
The ideas below take a few minutes or less, work in almost any subject, and need little or no preparation. Pick two or three and rotate them so they stay fresh.
Why quick checks beat big ones
A short check gives you information you can act on right away. If most of the class gets a question right, you move on with confidence. If answers are split, you know exactly where to slow down. Students benefit too: they find out what they know before the gaps pile up, and they get used to showing their thinking without the pressure of a grade.
10 ideas you can use tomorrow
1. The one-question poll
Ask a single multiple-choice question tied to the key idea of the lesson. Keep the options short and include at least one answer that reflects a common mistake. The spread of answers tells you more than the number who got it right.
2. Confidence ratings
Ask students to rate how confident they feel about today's skill on a scale of 1 to 5. Pair it with a quick problem. When confidence is high but accuracy is low, you have found a misconception worth addressing.
3. Explain it in one sentence
Pose an open question such as "In one sentence, why does ice float?" Short written answers reveal reasoning, not just recall, and they are fast to scan.
4. Find the number
For math and science, ask for a single numeric answer: "What is 15% of 80?" or "How many protons does a carbon atom have?" Wrong answers often cluster around the same error, which makes the mistake easy to diagnose.
5. Sort it out
Give students five or six items to put in order: steps of a process, events on a timeline, or fractions from smallest to largest. Sorting shows whether they understand the relationships, not just the individual facts.
6. Match the pairs
Terms and definitions, countries and capitals, causes and effects. Matching tasks are quick to answer and quick to check, and they make a good warm-up.
7. Word association
Ask "What word comes to mind when you hear democracy?" and look at what comes back. You will see the vocabulary students already have, and the gaps.
8. The muddiest point
Ask "What is still confusing about today's topic?" Students who would never raise a hand will often type an honest answer, especially when responses are anonymous.
9. Spot the error
Show a worked example with a deliberate mistake and ask students to find it. This flips the usual question around and tests whether they can apply the rule, not just repeat it.
10. Predict before you reveal
Before a demonstration, a video, or the next chapter of a story, ask students to predict what will happen. Predictions surface hidden assumptions and make the reveal far more memorable.
Making the answers useful
Collecting answers is the easy part. The value comes from what you do in the next two minutes. A few habits help:
- Decide your threshold in advance. For example: "If most of the class gets this right, I move on. If not, I reteach with a different example."
- Look at the wrong answers. Which option was most popular among students who got it wrong? That tells you which misconception to tackle first.
- Show the results. Seeing the class spread helps students realize they are not the only ones who are unsure.
- Follow up with a second question. After reteaching, ask a similar question to see whether the fix worked.
Tip: Keep a short bank of check questions for each unit. Over time you will learn which ones reliably reveal misunderstandings, and you can reuse them every year.
Doing this in LetMeAdd
All ten ideas map onto question types in LetMeAdd. Students join from a phone or laptop with a 6-character code or QR code, and nobody needs an account. Use multiple choice for one-question polls, a rating question for confidence checks, an open question for one-sentence explanations and muddiest points, find a number for numeric answers, sorting and matching for ordering and pairing tasks, and a word cloud for word association.
Turn on anonymous participation when you want honest answers about what is confusing. Because an event can be run as several live sessions, each with its own results, you can reuse the same set of questions across different class periods and compare how each group did. Short on time? Start from a ready-made template such as the lesson check-in or exit ticket and adjust the questions to your topic.
