Two cards, one question: higher or lower? The left card shows a real-world number — the height of a giraffe, the speed of a cheetah, the year of a discovery — and the class decides whether the hidden number on the right beats it. Streaks build, every reveal lands a fact worth talking about, and the close calls are deliberately sneaky. Type any lesson topic to generate a themed deck, or leave it blank for the random mix.
As a five-minute maths starter — it's estimation and number sense dressed up as a game, with pupils reasoning about magnitude, units and place value out loud. As a topic hook, with a themed deck generated for whatever you're teaching this week. Or as a Friday reward round in multiplayer: pupils join on their own devices with a QR code, everyone answers each card, and every right answer scores a point. Most points wins.
How does Higher or Lower work in the classroom?
Two cards show real-world things with a number — heights, weights, speeds, dates. The left card shows its value; the class decides if the right card's hidden value is higher or lower. Correct answers build a streak, and every reveal comes with a fact to talk about.
Can pupils play on their own devices?
Yes. In multiplayer, pupils join with a QR code or class code and everyone answers on their own device. Right answers score points, with more for answering fast, and the most points after 5 to 10 rounds wins. Nothing to install.
Can I make a themed deck for my topic?
Yes — type any lesson topic (the solar system, ancient Egypt, rivers…) and a themed deck of comparable facts is generated for it. Leave the theme blank for the built-in random mix. Generating a themed deck uses one token. Every account gets 20 free tokens, and Pro gives 50 a day.
What does it teach?
Estimation and number sense — pupils reason about magnitude, units and place value with real-world quantities — plus a stream of general knowledge from the fact behind every card.
Is Higher or Lower free?
Free to try. Starting a deck uses one token, built-in or generated. Coming back to one you have already made is free. Every account gets 20 free tokens, and Pro gives 50 a day.
