Level 1: Growing and moving

Change and motion · level 1 of 8 · rough age 5-6 (a guide for parents; anyone can start anywhere)

Everything around us changes: babies grow, ice melts, balloons go flat, the sky goes dark at night. In this level you learn to notice change and to talk about it with care: what changed, what stayed the same, which came first, and whether the change was fast or slow. These are the very first ideas of a big part of mathematics, which grown-ups later call calculus. Every lesson has pictures, little experiments to try at home, and questions with answers.

Lesson	You will be able to
Bigger and smaller over time	Put pictures of something growing or shrinking in order from first to last, and explain how you knew
Fast and slow	Say who is faster in a race by looking at how far each one went in the same time
Before, now and after	Tell what changed and what stayed the same, like when ice melts or a balloon loses air
Filling and emptying	Tell if something fills or empties the same all the way, or fast at first and then slower
Changes that come back	Spot changes that repeat, like day and night, the seasons and the shape of the Moon
Steep and gentle	Compare a steep ramp and a gentle ramp, and say which one makes a ball go faster
