"Open your books to page twelve, copy the date and title, underline it, then do questions one to five and check your answers with your partner." A child with a small working memory hears the first two steps and loses the rest. They are not being lazy or defiant when they sit and wait; they genuinely have nowhere to keep the instruction. Chunking is the habit of giving information in pieces a child can hold, one at a time, with something to look at. It is one of the highest-value classroom techniques because it costs nothing and helps almost every learner.
Why it works
Working memory is the small mental space where we hold and use information for a few seconds. Its size varies between children and it is easily overloaded by long instructions, unfamiliar words, noise and anxiety. When it overflows, the child loses the task, not just part of it. Chunking keeps the load inside what the child can carry, so the effort goes into the work rather than into remembering what the work was.
How to chunk instructions
- One step at a time. Give the first step, watch it start, then give the next.
- Say it, show it, leave it. Speak the step, write or draw it on the board, and leave it visible until the step is done.
- Number the steps. Numbers turn a stream into a list that can be checked off.
- Front-load the action. "Underline the title" is easier to hold than "the title, which you will find at the top, needs to be underlined".
- Check back, not "do you understand?" Ask the child to tell you the first step. If they can, they have it.
How to chunk tasks
Break a long task into parts with a visible finish line for each: a box to tick, a line to draw, a mini-goal. A worksheet with three questions on it three times is easier to start than the same nine questions on one page. For writing, chunk by sentence or by section with a prompt for each. For reading, chunk by paragraph with one question to answer before moving on.
Keep the expectation, change the delivery
Chunking is not about giving less. The child completes the same task; they complete it in pieces. Over time, the pieces get bigger. A useful test each half term: can this child now manage two steps together where they needed one? If yes, join the chunks. Scaffolding that never shrinks becomes a ceiling.
At home
Homework and routines respond to the same approach. "Get ready for school" is a chunked routine waiting to happen: bag, water bottle, shoes, coat, each said or shown one at a time. For homework, cover everything on the page except the current question.
What to track
Choose one lesson a day and count the number of times the child needed the instruction repeated, or the number of steps they completed without prompting. Record it for a fortnight. Chunking usually shows an effect within days; if nothing changes, the barrier may be the language of the instruction, attention, or something else, and the observation is worth sharing with the inclusion lead.
When to escalate
Speak to the inclusion lead if the child struggles to hold even a single short instruction, if the difficulty is much greater than for other children of the same age, or if it comes with difficulties in reading, spelling, maths or language. These patterns can point to needs that deserve assessment, and chunking should continue while that happens.
