Pairs of students use dice to create a rectangle (roll up a rectangle), sketch it on game sheet (worksheet), then one works out area and the other works out perimeter, based on rolled characteristics. Use of measurement units and squared units is essential. Next time students switch math task.
Students get into the swing of random multiplication problems and will aim for speed. Game encourages practice of area and perimeter problems, and faster assimilation of method through play and discussion.
Use of polyhedral dice is advised. 3 different duplex game sheets included:
- introductory sheet (for 6-sided dice)
- next sheet (for 4-sided, 6-sided and 8-sided dice)
- advanced player sheet (for 4-sided, 6-sided, 8-sided, 10-sided, 12-sided and 20-sided dice).
At each playing, students will create 10 different rectangles on the duplex sheet, so each student has 5 area and 5 perimeter problems to work out.
Competition aspects can be included. Teachers may award a prize for fastest finishers, longest perimeter, largest area (varying these randomly). Winning student may choose a class reward (Free time on Friday, extra time listening to class novel etc).
As students gain experience, this can become a fast finishers' activity to keep them math-sharp.
