Students complete a table showing the number of matchsticks used to build a series of pentagons. They identify the number of matchsticks required for a given pentagon and state the rule as an word equation.
Students use the Modified Mercalli intensity scale to assign magnitudes to three described earthquakes. Then they interpret data about the distance from an epicentre, and explain why, from given information, one earthquake might be more damaging than another.
