Online maths classes for learners in Peru

Source: INEI, Estadísticas de las Tecnologías de Información y Comunicación en los Hogares, second quarter of 2026 (ENAHO), read on 9 November 2026. INEI counts the Constitutional Province of Callao inside Lima Metropolitana and marks the 2026 figures as preliminary.

# Households with internet, % (INEI, II quarter 2025 and 2026)
areas = {
    "Lima Metropolitana": (80.4, 84.7),
    "Other urban areas": (62.7, 66.2),
    "Rural areas": (23.7, 27.1),
}

for name, (before, after) in areas.items():
    print(name, "grew by", round(after - before, 1), "%")

areas = {
    "Lima Metropolitana": (80.4, 84.7),
    "Other urban areas": (62.7, 66.2),
    "Rural areas": (23.7, 27.1),
}

print("area | points | per cent of the old figure")
for name, (before, after) in areas.items():
    points = after - before
    relative = 100 * points / before
    print(f"{name} | {points:.1f} points | {relative:.1f}%")

biggest_points = max(areas, key=lambda n: areas[n][1] - areas[n][0])
biggest_relative = max(areas, key=lambda n: (areas[n][1] - areas[n][0]) / areas[n][0])
print("Most points:", biggest_points)
print("Fastest growth:", biggest_relative)

The ranking flips. Lima added the most points but grew the least relative to where it began; rural homes added the fewest points but their share of homes online rose by about a seventh in a single year. The biggest jump in points was the slowest growth. Both statements are true at once, and a careful writer says which one they mean.

There is a second lesson underneath. A small starting number makes relative growth look dramatic, so neither measure is "the honest one" on its own. We ask learners to write one English sentence that uses both, for example: "Rural home internet rose by 3.4 percentage points, a 14% increase on 2025, but it still reached only about a quarter of rural homes." That sentence would survive any fact-checker.

1. Ages 9 to 11, no code. A class had 20 children and now has 25; another had 4 and now has 8. Which class grew more? Which grew faster? Explain the difference in one sentence.
2. Ages 12 to 14, on paper. Using the computer column in the table, say how many points separate Lima from rural areas. Then say how many times more likely a Lima home is to have a computer.
3. Ages 14 and up, Python. Run Version 1, then fix it without looking at Version 2. Add the national figures, 60.7% in 2025 and 64.5% in 2026, and see where Peru as a whole lands.
4. University and adults. Find one news headline that says "rose by X%" about a percentage. Decide whether it means points or per cent, and rewrite it so nobody can misread it.

1. Choose the screen. A laptop or desktop is best; a tablet with a stylus or keyboard is workable. Keep the phone for WhatsApp messages with the teacher.
2. Test the connection at the class hour. Run a short video call at the same time of day as the planned class, because evening connections in a busy home are often slower than morning ones.
3. Find a quiet corner. A table, a chair, decent light on the learner's face and paper within reach. Maths is still worked on paper as well as on screen.
4. Use a headset if you can. A cheap headset with a microphone removes echo and makes the teacher's English much easier to follow.
5. Agree the hour on your own clock. You book in Peru time and the teacher's calendar converts it. Nothing changes between summer and winter, because neither country moves its clocks.
6. Tell us the school topic. If a test is coming, say which chapter. Live lessons can follow the school's order when that helps.

A parent does not need to sit beside a learner of ten or older for the whole class. For a six or seven year old, a grown-up nearby for the first few lessons helps with the camera, the microphone and the occasional lost cursor.

Any day, any time: weekday, weekend, morning or night in Peru. Our teachers work across the Indian day and night so that a learner in Peru does not have to. When you book a free class you pick the hour on your own clock, and the confirmation shows it in Peru time.
