Meet the Mathix
Out of all of space, there are only FIVE perfectly even 3-D shapes: the five Platonic solids: and kids already roll them as dice: Tetra is the d4 (4 faces), Cubo the everyday d6 cube (6), Octa the d8 (8), Dodeca the d12 (12), and Icosa the d20 (20). Count the faces, count the shapes: and the magic is that the counting stops: only five, and that is all there can ever be.
stomp-stomp — clap! — tuba: ooom-pah!
[ALL] Count the shapes, count the faces — go! Only five in the whole wide show! (stomp-clap!)
[TETRA] I'm Tetra! Roll me — count my sides... [KID] One, two, three, four! [TETRA] Four little triangles, sharp as a kite — the tiny d4, I land on a point upright! (boing!)
[ALL] Count the shapes, count the faces — go! One of five, here we go-go-go!
[CUBO] I'm Cubo the cube — you roll me every day! [KID] Two, four, six! [CUBO] Six flat squares, the die in your game, snake-eyes and sixes — the d6 is my name! (roll-tumble!)
[ALL] Count the shapes, count the faces — go! Two of five, watch the number grow!
[OCTA] I'm Octa — two pyramids stuck base to base... [KID] Count 'em — eight! [OCTA] Eight little triangles spinnin' in space, the d8 diamond, I tumble with grace! (whirl!)
[ALL] Count the shapes, count the faces — go! Three of five — almost the whole show!
[DODECA] I'm Dodeca! Pentagons all the way round... [KID] Whoa — twelve?! [DODECA] Twelve five-sided faces, I'm fat and I'm round, the big d12, I go thunk on the ground! (thunk!)
[ALL] Count the shapes, count the faces — go! Four of five — one more to go!
[ICOSA] I'm Icosa — the giant! Count if you dare... [KID] Ten... fifteen... twenty! [ICOSA] Twenty triangles, faces everywhere, the mighty d20, I roll like a bear! (rumble!)
[KID] So who comes next? A six? A new one? [ALL] Nope! That's all — only five! (stomp-clap — done!) Out of all of space, just five fit right, every face matching, perfectly bright!
[ALL] Tetra, Cubo, Octa — say it with me! Dodeca, Icosa — we're the whole family! Atoms made the rules, now the shapes obey — five perfect dice... and there's no number six to play! (ooom-pah — stomp!)
[ICOSA] Four... six... eight... twelve... twenty... [ALL] and that's all — only five! (clap!)
