AlwaysTots
Testle the tortoise says a rule about block towers, like "a tower with more blocks is taller". Is it always true, sometimes true or never true? Guess, then test it on three towers and let the blocks decide. Then try to break a rule with real blocks. Ages 3–5, with a grown-up.

Meet the cast
AlwaysTots's friends play with block towers. Testle tests every rule, Stackle stacks the blocks, Breakit hunts for the tower that breaks a rule, and Samey builds two towers out of the same blocks.
Testle
tests a rule on tower after tower before saying it is always true
Stackle
A beaver who stacks - puts one more block on top and watches the tower grow
Breakit
A cheeky magpie - looks for the one tower that breaks the rule, because one is enough
Samey
A mouse with two towers - builds both from the same blocks in a different order, and they are just as tall
