Mini-Whiteboards
A whole-class response tool where every learner writes their answer on a small whiteboard and holds it up simultaneously, giving the teacher instant feedback on understanding.
What is mini-whiteboards?
- Pose a question to the whole class
- Give learners thinking time to write their answer on a mini-whiteboard
- On a signal, all learners hold up their boards at the same time
- Scan responses quickly and respond to what you see
How it works
Mini-whiteboards transform classroom questioning from a one-at-a-time activity into a whole-class response. Instead of one learner answering while twenty-nine remain passive, every learner commits to an answer and makes it visible simultaneously.
The key is the simultaneous reveal. If learners hold up boards one at a time, they copy each other. When everyone reveals at once, every response is genuine. This gives the teacher instant diagnostic information: are most learners secure, or is there widespread misunderstanding?
Mini-whiteboards work for quick-fire recall questions, longer worked examples, diagrams, spellings, calculations, and short written responses. They are equally effective in Mathematics, Languages, Science, and Humanities. The erasable surface encourages risk-taking because mistakes can be wiped away instantly, which lowers anxiety about being wrong.
Use the responses diagnostically. If most boards show the correct answer, move on. If several show a common misconception, address it immediately. If responses are split, pair a correct learner with an incorrect one and let them discuss before trying again. This makes mini-whiteboards one of the most efficient formative assessment tools available.
Classroom example
A Year 5 Mathematics and Numeracy class in a Powys school is practising equivalent fractions. The teacher writes 2/4 on the board and asks learners to write an equivalent fraction on their whiteboards. On the count of three, all boards go up. Most show 1/2, several show 4/8, and two show 3/6. One board shows 2/8. The teacher sees the misconception immediately and works through it with the class, using the correct responses as models.

Mini-whiteboards develop the "Reflect" strand of thinking skills by requiring learners to commit to and evaluate their own responses. They support cross-curricular numeracy and literacy by providing a low-stakes space for practising core skills across all AoLEs.
Rainbow Curriculum's Thinking Tools lens helps you plan where whole-class response tools are used across your curriculum, ensuring formative assessment is embedded in everyday teaching.
Tips
- Insist on simultaneous reveal. Boards must go up together, not one at a time.
- Provide board pens that actually work. Dried-out pens kill the activity.
- A common pitfall: asking only closed questions. Mini-whiteboards can also be used for short explanations, diagrams and worked examples.
- Use "show me" as your signal phrase so it becomes routine.
- Pair with "no hands up" questioning to keep all learners engaged between whiteboard activities.
