The six activities
How to use Number Sense

Begin with the initial skills check, or select a starting level for each activity. Use short teaching sessions to model, discuss and practise. Then use an independent check with no hints or adult prompting. Record help honestly using “I need help”.

The skills check samples six items at each level, stopping an activity at the first level that needs teaching. Six correct responses without help or interruption allow the next level. Pause whenever needed. It suggests a starting point; confirm understanding by asking the pupil to explain or show their answer with real objects, and by checking again on another day. It is not a standardised test or diagnosis.

Two completed independent checks with at least 5 of 6 correct at the same level can move the next session up one level, if automatic progression is enabled. Supported or interrupted checks never qualify. Use different everyday examples and check on another day before treating a skill as secure. Accuracy, understanding, access needs and wellbeing matter; response times alone do not measure ability.

For older pupils, use the same neutral counters and short instructions alongside age-appropriate real-life tasks. No age labels or competitive scores are shown.

Teaching principles: NCETM: cardinality and counting, composition, and EEF: early mathematics guidance. These sources inform the design; this app has not itself been evaluated as an intervention.
