If the game is being played to help reinforce the workbook and terminology THEY HAVE ALREADY LEARNED, consider playing with this additional twist.
For each "period" the pawn lands on a step. A player on the team must define what that step is. Rotate the assignment to state the definition between players. Instruct teams to select who will be the first definer before they begin.
Briefly (and in your own words) define the step. If player can define it without resources, there is no penalty. If they have to look it up in the glossary, they should look it up – read it and as a penalty, take one team member pawn off the game board.
