Original worksheet library

View Sigma development history
Topic worksheets and test questions are generated inside Sigma Maths. The worksheet engine uses explicit topic mapping, answer validation, mark allocations and duplicate-question protection. v18 introduced typed answers, saved workings and automatic worksheet marking; v19 added the Sigma learning journey and readiness interface; v20 added Sigma Times Storm for adaptive multiplication fluency; v21 added original retro tracker music and responsive game sound effects; v22 added the Home arcade theme. v24 restored the complete regression-locked build. v25 added wave upgrades and boss progression. v26 added the full Sigma Storm Deluxe arcade interface, multiple game modes, event waves, animated combat feedback and a compressor-limited high-output audio system. v27 added a first-party Sigma Tutor lesson to every one of the 116 topics. v28 added an adaptive learner model with Guided/Building/Independent/Challenge modes, misconception coaching, Rescue Mode, Sigma Sprints and spaced retrieval. v29 added Maths Keys and alternating Sigma Blaster Breaks. v30 added branching Higher-topic lessons, a prerequisite dependency map with Foundation Repair Missions, automatic return-to-topic flow, curriculum weak-point awareness in Sigma Storm, learning-powered arena unlocks and a capped mastery score boost. v31 added five colour-coded arcade sectors, enemy formations, six named rival bosses with phase escalation, mature Sigma comms, personal-best chasing and run medals. v32 added an eight-level saved Mission Campaign with story objectives, division, squares, roots, powers, missing-factor and percentage puzzles, mixed finale missions and variable 10–16 second combat breaks. v33 added a large in-game touch answer pad with 0–9, clear, backspace and FIRE/ENTER controls. v34 added a dedicated Σ NOVA bonus-weapon button, maths-powered charge meter and tactical Nova fire during falling-threat and shooter sections. v35 added four starting lives, a retro bottom-right life rack, 1-UP carriers, a retro GAME OVER state and rotating shooter enemy classes. v36 adds a cabinet-style arcade answer controller, richer action-specific SFX, eight visually distinct boss characters and removes Tutor Live screen-sharing/whiteboard UI for now — still with no third-party teaching links. v37 added Sigma Exam Intelligence: multi-stage Grade 6–9 reasoning problems, optional method checkpoints, partial method marks, first-error diagnosis, mark-weighted exam papers and a provisional predicted-grade/readiness model driven by independent evidence. v38 added Sigma Daily: a saved 6-question personalised Daily Mission, spaced retrieval, priority repair, current-topic practice, adaptive Grade 6–8 exam challenge, 5/7 Weekly Core, Streak Shield and Weekly Boss unlock. v39 added the Sigma Adaptive Mastery Ladder: topic worksheets change difficulty from learner evidence, adaptive module/mixed papers weight weaknesses and under-tested skills, GCSE Exam Simulation remains balanced, and selected high-security topics can unlock Pearson Edexcel AS Mathematics bridge questions without affecting the GCSE predicted-grade calculation. v40 added visible Starter → Timber → Bronze → Silver → Gold/Σ Mastery ranks to worksheet and module-paper controls, seven-day Review Due freshness, retrieval defence and temporary AS-Bridge pausing instead of automatic time-only demotion. v41 adds the production-style Sigma account gateway: sign in, create account, email verification state, password recovery and guest mode, with a Supabase-ready authentication adapter while local maths progress remains preserved. v42 adds Sigma Identity: original illustrated avatars, username onboarding, XP progression, Bronze/Silver/Gold avatar frames, profile achievements and a cloud-ready weekly leaderboard foundation. v43 adds the Sigma Adult Ecosystem: Teacher Intelligence, mastery heatmaps, priority intervention worksheets, adaptive assignment scaffolding, Parent Progress and weekly parent-report preview, while multi-user class/parent linking remains explicitly gated behind secure cloud roles. v44 adds visible app-version labelling, a service-worker-backed update checker/restart flow and safe device-removal guidance without erasing learner progress. v45 introduced Sigma World: seven visual syllabus zones that replace the all-topics wall while preserving the full colour-coded topic workflow inside each module. v46 upgraded Sigma World visually with a premium illustrated island map. v47 added clearer module labels and an upgraded modules area beneath the map for faster navigation. v48 refines the map labels into premium location callouts with stronger progress states and a cleaner quick-access module panel.
