Developing Success Criteria for Rich Tasks

Hi esteemed colleagues! Tonight’s Numeracy staff meeting will be based on developing Success Criteria around Rich Mathematical Tasks that promote Understanding, Fluency, Problem Solving and Reasoning. But before we get stuck in have a go at solving this riddle…

3 men go into a hotel. The man behind the desk says a room is $30 so each man pays $10 and goes to the room.

A while later the man behind the desk realized the room was only $25 so he sent the bellboy to the 3 guys’ room with $5. On the way the bellboy couldn’t figure out how to split $5 evenly between 3 men, so he gave each man a $1 and kept the other $2 for himself.

This meant that the 3 men each paid $9 for the room, which is a total of $27 add the $2 that the bellboy kept = $29. Where is the other dollar?
