🦹 Hero Team Builder — a free maths game for kids
The mission needs 8 strength, 10 speed, 12 brains — and you may only pick three heroes.
This is a data table children want to read. Adding three columns, comparing each total to a threshold and then doing it again under a budget is exactly the reasoning behind later work with inequalities — met here as a squad selection rather than as notation.
How to play
- 1Read the mission requirements — minimum strength, speed and intelligence.
- 2Study the hero table. Every hero has three stats and a recruitment cost.
- 3Pick a squad whose totals meet every requirement.
- 4Later missions cap the squad size and the budget, so the cheapest team that still clears the bar wins.
Frequently asked questions
- What skill is this really practising?
- Column addition, comparison against a threshold, and constrained choice. It is the friendliest introduction to optimisation a young child can get.
- Is there one right team?
- Often several teams work, and later missions add a budget so that only some of them are affordable — which is where the thinking gets interesting.
- What grades suit it?
- Grade 1 upward. Early missions use two stats and small numbers; upper grades use three stats, a squad cap and a point budget.
- Is it free?
- Yes, free with no signup.
