The five A4 SVG/PDF vector sheets are write-on teaching diagrams, not answers. They use text, box edges and labels as well as colour. This page preserves their full instructional meaning for screen readers, enlarged text, oral/AAC presentation and raised-line/counter routes. The SVGs also include a title and description. Do not infer a student's mathematics from their preferred access mode. All values and supplies in these diagrams are invented. Use the learner cards for all scenario conditions and the public teacher key after first responses.
Period converter · SVG · PDF
Heading: PERIOD CONVERTER. Subtitle: Card A; use a divisor that matches the period named in your answer. First panel says GROSS ANNUAL MODEL AMOUNT: $65,520 per year. Assume equal model periods: 52 weeks, 26 fortnights, 12 months. Three separate blank panels, in order:
- WEEK:
$65,520 ÷ 52 = ____. Reverse check:amount × periods = ____. - FORTNIGHT:
$65,520 ÷ 26 = ____. Reverse check likewise. - AVERAGE MONTH:
$65,520 ÷ 12 = ____. Reverse check likewise.
Footer caution: a gross-period model is not a net payslip or guaranteed calendar amount. Tactile/large-text route: give one raised strip labelled ANNUAL and three textured strips labelled WEEK/FORTNIGHT/MONTH. Put the appropriate 52/26/12 count beside each, then write or dictate quotient and reverse product. Avoid using colour as the only period cue.
Payment models · SVG · PDF
Heading: PAYMENT MODELS. Subtitle: Cards B–C; rate times matching count, or base plus percentage of sales. Upper panel: MODEL 1 · PAID HOURS. 5 paid hours × $32 per paid hour = ____; then blank “Model total has units: ____” and “What real work condition is unknown?” Lower panel: MODEL 2 · ACCEPTED PROPS. 20 accepted props × $9 each = ____; Try 15 accepted props: ____; First whole count above $160: ____. It also reminds: Base-plus-commission: base + percent × eligible sales. Footer says to compare totals for matching stated conditions, not isolated rate labels. Tactile/large-text route: put five “paid-hour” counters in one labelled tray and 20 “accepted-prop” counters in a second; match each rate card to its own tray. For commission, use a separate BASE tray and SALES-PERCENT tray; do not merge their rate bases.
Budget category mat · SVG · PDF
Heading: BUDGET CATEGORY MAT. Subtitle: Card D; preserve essential/discretionary categories before subtracting. First panel says STIPULATED WEEKLY MODEL INCOME: $1,260; gross is treated as available only in this exercise. Five vertically ordered rows: Fixed costs $680; Variable essential $220; Discretionary $110; Total planned $____; Unassigned $____. Final box: Reverse check: planned + unassigned = income. Footer: unlisted real costs/deductions remain unknown. Tactile/large-text route: use five trays with raised printed row names and one counter per $10 or written amount token; keep FOOD inside “variable essential.” The final two trays are arithmetic results, not recommendations.
Price-base ladder · SVG · PDF
Heading: PRICE BASE LADDER. Subtitle: Card E; two different directions under a fully taxable assumption. Upper panel: EXCLUDING GST → INCLUDING GST. This is a stipulated fully taxable fictional item. exclusive base × 0.10 = GST; exclusive base × 1.10 = inclusive total; $84 → GST ____ → total ____. Lower panel: INCLUDING GST → EXCLUDING GST. inclusive total ÷ 1.10 = exclusive base; included GST = total − base; $121 → base ____ → GST ____. Footer: actual GST classification is not established by this teaching card. Tactile/large-text route: label three boxes BASE, GST, TOTAL. For the forward direction, start in BASE. For reverse, start in TOTAL and find BASE first. An arrow is reinforced by the written direction label.
Simple-interest timeline · SVG · PDF
Heading: SIMPLE-INTEREST TIMELINE. Subtitle: Card F; each annual strip comes from the original principal. Top panel: SIMPLE INTEREST · SAME ORIGINAL PRINCIPAL, I = P × i × n, A = P + I, P=$2,400, i=0.035 per year, n=2 years. Two ordered panels: YEAR 1 and YEAR 2, each says 3.5% of original $2,400 = ____ and “Do not move the percentage base.” Last panel: Total interest: ____; Final model amount: ____; “No compounding, fees, tax or real product.” Tactile/large-text route: place two equal annual-interest strips against a stationary raised principal card; neither year starts from the year-1 total. Learner states original P each time.
For embossing or tactile adaptation, use actual labelled text strips and edges; verify tactile contrast, spacing and legibility with the individual learner. This document describes a possible route and does not claim that a specialist tactile version or user validation has already been produced.
