SASHA Learning Brief
Maths Fluency: Look Beyond the Stopwatch
A practical way to look at mathematical accuracy, strategy and explanation, with a careful distinction between timed tests and supported fluency practice.
Ask what the answer tells you
Imagine a learner answering 19 + 6. They might count on, make 20 and add the remaining 5, or recall the answer. Each route can produce 25. A stopwatch records how long the response took, but an explanation gives the adult another useful observation: how the learner approached the calculation. This is a fictional teaching example, not an account of a particular learner.
Before choosing a practice activity, name its purpose. Are you introducing an idea, practising a familiar calculation or checking which strategy a learner can use? These questions lead to different activities. This brief offers a small discussion exercise for making the reasoning visible; it does not diagnose a learning difficulty or prescribe an individual support plan.
Fluency includes choosing a method
The National Council of Teachers of Mathematics' January 2023 position statement describes procedural fluency in terms of accuracy, efficiency and flexibility, including choosing procedures that suit the problem. It recommends assessment through observations, interviews and written prompts, and advises against timed tests as a measure of fluency. This is a professional position statement, not a study of a particular app.
For the addition example, ask: 'Why did you choose that method?' Then change the numbers and ask whether the same approach still fits. Listen to the explanation before demonstrating another route. The aim of this conversation is to identify a useful teaching question, rather than to reward the longest explanation or require everyone to use one preferred method.
Read the timing guidance in context
There is an important qualification. The U.S. Institute of Education Sciences' March 2021 guide for mathematics intervention in grades K–6 recommends brief timed activities as one part of a wider programme. It says to use them after a concept has been studied over many lessons, rather than to introduce new concepts. The panel also emphasises suitable strategies and feedback, and addresses concerns about guessing and anxiety.
NCTM's advice about assessment and IES's recommendation for supported practice should both remain visible. These sources do not justify saying that every timer prevents learning, or that a timed score captures everything a learner understands. An educator needs to consider the activity's purpose and the learner's response. Keep agreed accommodations in place and discuss difficulties with the teacher or support team.
Try a short reasoning conversation
Here is an original exercise to adapt with an educator. Choose one familiar calculation at an appropriate level. Ask the learner to solve it using their usual supports, then explain or show one step. For 19 + 6, a drawing or number line could show the move to 20 and then to 25. Check that the representation matches the calculation, rather than treating the presence of a picture as evidence by itself.
Next, offer 29 + 6 and ask what changes and what stays the same. Check the answer together against the taught method or another trusted reference. If the learner needs a hint, record the hint alongside the attempt. Adapt the way they respond to their communication needs. This proposed exercise is not a validated assessment, an optimal practice schedule or a promise of improved attainment.
Make the observation useful for teaching
The Education Endowment Foundation's 2017 guidance for Key Stages 2 and 3 recommends using assessment to identify what pupils know and to inform subsequent lessons and targeted support. Its focus is teaching in those stages; it should not be presented as a universal prescription for every age or setting.
A compact note from our fictional exercise might read: 'Used the move-to-20 strategy independently; needed a prompt to adapt it to 29 + 6.' That gives the next adult a specific question to revisit. Include the support used and any uncertainty. If the learner says the task felt rushed or unclear, preserve that feedback in their own words rather than guessing its cause.
Ask a learning tool to show the reasoning
In a product demonstration, use fictional calculations and ask what a completion score leaves out. Can the adult review the learner's method and the help provided? Can an inaccurate observation be corrected? Is the intended purpose of a timed activity explained? These are questions to investigate, not a checklist that certifies educational quality.
They apply to SASHA too. The sources below do not establish SASHA's effectiveness or confirm any feature's public availability. Start with the teaching decision: what does this learner understand about this calculation, and what would be useful to practise next? A clear answer to that question is more actionable than a speed score on its own.
