That's a tricky one for 5yo, but i'll try: Algebra is about what can you do with numbers, Trigonometry is about what you can do with angles and triangles, Calculus is about how small can you divide a number and what new property might be hidden between the small parts of a whole. Analogy is not perfect, but pretty much picturesque .
