Monster Potion

Tembii the witch is stirring a bubbling cauldron in a lantern-lit pumpkin patch, and the whole class is cooking with her. Answer a question right and three silly ingredients appear, such as a stinky sock, a rubber duck or a whoopee cushion. The class picks one and drags it into the pot, Tembii says its name out loud, and the slime monster inside turns that colour and grows. Eight ingredients later it bursts out of the pot for a happy finale, every time. A wrong answer costs nothing, so the youngest learners can play without worry.
