A 20-question review game with 5 questions about customary units of length, 5 questions about customary units of capacity, 5 questions about customary units of weight, and 5 questions about the metric measurements.
Slides are linked to show the answer next and then to return back to the choice menu. Answer slides have detailed explanation to help reteach students who missed the question. I demonstrate customary conversions using ratios and metric unit conversions using a short-cut involving a phrase to remember metric prefixes in order.
This can be played as a large group or students can play independently.
