Five-minute formative checks that actually tell you something

<p>Most primary classrooms now do some form of end-of-lesson check. Exit tickets, mini-whiteboards, traffic-light self-assessment, thumbs-up-thumbs-down. The intent is good — find out who got it before they leave the room — but a lot of the practice is theatre. Children write or hold something up, the teacher sees it, the lesson ends, the next lesson is taught the same way it was always going to be taught.</p> <p>Useful formative assessment is different. It actually changes what you do next. Here are five end-of-lesson checks that meet that test, and a few that don't.</p> <h2 class="article-section-heading">What makes a check actually useful</h2> <p>Three criteria. A formative check is doing its job if:</p> <p>1. <strong>It can be answered correctly only if the child genuinely understands</strong> — not by guessing, copying, or restating something heard. 2. <strong>It reveals enough children's wrong thinking that you can plan tomorrow's lesson differently if you need to.</strong> 3. <strong>You actually look at the responses before next lesson.</strong> A check whose answers you don't read is decoration.</p> <p>If a check doesn't meet all three, it's compliance theatre. You can use it for routines if you want, but don't pretend it's assessment.</p> <h2 class="article-section-heading">Five checks that work</h2> <h3 class="article-sub-heading">1. The hinge question</h3> <p>A multiple-choice question with carefully designed wrong answers. Each wrong answer reveals a specific misconception. Asked at a 'hinge point' in the lesson — typically near the end of the input.</p> <p>Example for Y4 fractions:</p> <p>> Which of these is the largest? > a) 1/2 b) 1/3 c) 1/4 d) 1/8</p> <p>The wrong answers aren't random. A child choosing 'd' is likely thinking the bigger denominator means the bigger fraction (the most common misconception). A child choosing 'b' might be confused by familiarity. A child correctly choosing 'a' has understood that as the denominator gets bigger, the parts get smaller.</p> <p>You can do this on mini-whiteboards (every child holds up A/B/C/D), and you can see the whole class's understanding in fifteen seconds. If most are wrong in the same way, you reteach tomorrow. If only a few are wrong, you make a note and target them in tomorrow's group work.</p> <h3 class="article-sub-heading">2. The 'show me three' check</h3> <p>Children write three examples of something on a whiteboard or in their book. Three because: one example might be lucky; two might be patterned; three usually requires understanding.</p> <p>Examples: - Show me three different ways to make 24. - Show me three sentences using a fronted adverbial. - Show me three things that are alive but not animals. - Show me three different fractions equivalent to 2/3.</p> <p>The brilliance is that wrong examples are immediately visible. A child who writes '20+4, 22+2, 23+1' is doing addition correctly but limited; a child who writes '6×4, 100−76, 4²+8' has more flexibility. Both are 'right' but tell you different things about the child's mathematical confidence.</p> <h3 class="article-sub-heading">3. The wrong-answer explanation</h3> <p>Show the class a wrong answer. Ask them to explain what mistake the (made-up) child made.</p> <p>> Sam writes: 'The cat sat on the mat, it was tired.' > Sam thinks this sentence is correct. Explain what's wrong and how to fix it.</p> <p>Children who can identify and explain the comma splice have understood it deeply. Children who can't, but can correctly write their own sentences, may have surface knowledge only. Children who can't even spot the error need reteaching.</p> <p>This is much more diagnostic than asking 'write a sentence with a comma' — which most can do without understanding the rule.</p> <h3 class="article-sub-heading">4. The two-minute summary</h3> <p>At the end of the lesson, every child writes (in two minutes, no longer) a sentence answering: <strong>'What did we learn today, and how could you tell someone else?'</strong></p> <p>You collect these. Read them. Don't mark them — just read.</p> <p>You'll see three groups within minutes: - Children who can paraphrase the learning correctly in their own words. They have it. - Children who can repeat phrases from the lesson but couldn't explain them. They have surface understanding only. - Children who write something irrelevant, vague, or wrong. They didn't understand.</p> <p>The third group is who you target tomorrow. The middle group is who you check in with during independent work next time.</p> <h3 class="article-sub-heading">5. The 'teach a Year 3' check</h3> <p>Older children explain something to an imagined younger child. The simplification reveals understanding.</p> <p>> Imagine you have to explain to a Year 3 child what fractions are. Write what you'd say in three sentences.</p> <p>Most children find this much harder than expected. The ones who do it well — using analogies, examples, simple language — clearly understand. The ones who repeat the lesson's vocabulary are revealing surface learning. Powerful diagnostic.</p> <h2 class="article-section-heading">Three checks that don't really work</h2> <p>A few common practices that look like formative assessment but mostly aren't:</p> <h3 class="article-sub-heading">Thumbs up / thumbs down</h3> <p>The intent is fine — quick read of the room. The reality is that children who don't understand often put their thumbs up because they've seen others do it, or because they don't want to admit not understanding. The signal is mostly noise.</p> <p>You can rescue this slightly by saying 'thumbs to your chest, low and quiet, only the teacher can see' — but the bigger fix is to ask a question whose answer reveals understanding rather than asking children to self-rate confidence.</p> <h3 class="article-sub-heading">Traffic-light self-assessment</h3> <p>Same problem. 'Show me green if you got it, amber if mostly, red if confused.' Children who are confused often show green to avoid attention. Children who fully got it sometimes show amber because they are perfectionists. The data is noisier than you'd think.</p> <p>Useful for whole-school visible learning culture. Less useful as actual diagnostic information.</p> <h3 class="article-sub-heading">'Any questions?'</h3> <p>The classic. The children who would benefit from asking questions are the children least likely to ask. The ones who do ask are usually the most confident, and their questions are often about extension rather than struggle.</p> <p>This is fine as a politeness ritual. It is not formative assessment.</p> <h2 class="article-section-heading">Making time for the looking</h2> <p>The biggest barrier to actually using these checks is reading the responses. You finish the day, you've done four exit tickets across four lessons, that's 120 little pieces of paper, and you have a staff meeting at 4:15.</p> <p>A few moves help:</p> <div class="article-callout"><span class="article-callout__label">Pick one lesson per day to do a serious check</span><span class="article-callout__body">Not every lesson needs an exit ticket. The lesson that introduces a new concept matters more than the lesson that practises a known one. Concentrate the assessment effort.</span></div> <div class="article-callout"><span class="article-callout__label">Read the responses on the carpet, while children pack up</span><span class="article-callout__body">Three minutes is enough to scan 30 short responses for patterns. You don't need to keep them.</span></div> <div class="article-callout"><span class="article-callout__label">Sort into three piles as you read: GOT IT / NEARLY / RETEACH</span><span class="article-callout__body">Not for marking. For your own planning. Tomorrow's lesson should explicitly start by addressing the RETEACH pile.</span></div> <div class="article-callout"><span class="article-callout__label">Tell the children what you saw</span><span class="article-callout__body">'Most of you got the main idea. About six of you mixed up the two types — we're going to do that again tomorrow before moving on.' This is genuinely useful information for them, and reinforces that the check mattered.</span></div> <h2 class="article-section-heading">The takeaway</h2> <p>Most formative assessment in primary classrooms is well-intentioned but ineffective. The intent is to gather information that changes what you teach next; the reality is rituals that gather noise and don't change what happens tomorrow.</p> <p>Useful checks have three properties: they require genuine understanding to answer, they reveal common misconceptions, and you actually read the answers before planning next lesson.</p> <p>If you only do one thing differently this term: pick one lesson a day, give a hinge question or a 'show me three' at the end, scan the responses while children pack up, and use what you see to start the next day. That's better than four exit tickets a day that nobody reads.</p> <p>Formative assessment matters. The question is whether yours is actually formative or just assessment.</p>
