Use paper, pencil, ruler and up to 36 large counters, tiles, sticky notes or drawn cells. Small loose items may be unsuitable for some groups; offer a printed/grid, magnetic large pieces, spoken factor pairs or a tactile card instead. The activities are mathematical representations, not instructions to change real rooms, repair equipment, spend money, use food, or collect personal data.
The three original one-page A4 aids can be printed or used on screen: factor-array lab, equal-whole fraction bars and 0–1/0–2 fraction lines. SVG versions and complete text/tactile routes are in the alternatives file. No colour meaning is required. Use dark large markers, enlarge as needed and let a learner state a factor pair or tick count if drawing is a barrier. Record the route used.
Before Day 11: Prepare cards 1,2,12,16 and example arrays. Before Day 15, keep its fresh numbers sealed from learners. Before Day 16: Prepare same-length unit strips divided into 2, 3, 4 and 12 equal parts. Check every strip has identical whole length; do not compare pieces from unequal wholes. Before Day 20, keep the held-out fraction pair and 24-tile context sealed. Read aloud from a check neutrally; supplying an answer or strategic hint changes the evidence.
Accessibility: A raised straight line with 12 equally spaced notches can replace a visual 0–1 line. For 0–2, use 24 equal notches with a distinct label at notch 12. Large factor cards can replace small counters. Screen reader users get the complete ordered wording and spatial relations in the text alternative. Speech, sign/AAC, pointing to labelled cards, typing, drawing or child-directed adult transcription are valid ways to express the same mathematical reason. Do not infer ability, diagnosis or a permanent “learning style” from a mode choice.
