Simu Primary, lesson by lesson
The foundation app for Basic 1–6: the full NaCCA maths and science curriculum as interactive lessons, plus a toy box of manipulatives — geoboards, fraction walls, circuit builders — that teach while they play.

Simu Primary covers Mathematics and Science for Basic 1–6 (roughly ages 6–12), built directly on the NaCCA curriculum. Every lesson maps to an official curriculum indicator, every example is Ghanaian — market stalls, cedis, charcoal, gari — and everything runs comfortably on a low-end Android phone.
Students open it from the Student Portal's app grid (or directly at primary.simusim.com with their student code + PIN). Family-account children get it through a purchase or subscription that includes Simu Primary.
The app greets the child by time of day — good morning, good afternoon, good evening — with their first name and today's date. Below the greeting:
Navigation lives in a bottom bar on phones (sidebar on bigger screens): Home, Lessons, Explore, Rewards, and Profile.
The Lessons tab organises everything the official way — by strand within each subject:
| Subject | Strands |
|---|---|
| Mathematics | Number · Algebra · Geometry & Measurement · Data |
| Science | Diversity of Matter · Cycles · Systems · Forces & Energy · Humans & Environment |
Pick the grade and strand, then a lesson. Each lesson carries its NaCCA indicator code (e.g. B4.1.1.2 — Basic 4, strand 1, sub-strand 1, indicator 2), so a teacher or parent can match it to the school's scheme of work exactly.
Lessons follow a consistent four-beat rhythm:
The Explore tab is free play with a purpose — six open-ended manipulatives and labs:
| Tool | Grades | What the child does |
|---|---|---|
| Geoboard | B2–B6 | Stretches virtual rubber bands over a peg grid to build shapes — perimeter, area and symmetry sneak in by themselves. |
| Pattern Blocks | B1–B4 | Tiles triangles, hexagons and rhombuses into patterns; tessellation and fractions hide inside. |
| Fraction Wall | B3–B6 | Stacks fraction bars to see that 2/4 and 1/2 are the same width — equivalence made visible. |
| Circuit Builder | B4–B6 | Drags batteries, wires and bulbs together; series and parallel circuits light up (or don't) instantly. |
| Food Web Builder | B3–B6 | Draws predator–prey arrows, then removes an animal and watches the ecosystem wobble. |
| Life Cycle Explorer | B2–B4 | Sequences the stages of a frog, butterfly, or plant. |
The daily goal card on the home screen serves one curated activity for the day, matched to the chosen grade — the easiest answer to “what should I do today?”. Ten minutes on the daily goal, most days, is the habit the app is designed around.
Completed lessons and mastered indicators flow into the wider workspace automatically:
Install the app when the browser offers (or via the browser menu → “Add to Home Screen”), tap the offline download card on the home page while connected, and lessons keep working without data. Progress made offline is saved on the device and syncs automatically on the next connection — see the general offline guide.
