|content= The lesson idea is about a mathematics investigation, where students explore whether two rectanges that have the same area also have the same perimeter. This is of course not the case, but nevertheless this can be a misconception. Students initially vote, then do an investigation, and finally vote again as well as present. The investigation offers an opportunity for same-task group work. | |content= The lesson idea is about a mathematics investigation, where students explore whether two rectanges that have the same area also have the same perimeter.

* How many properties of a rectangle (among height, width, area, perimeter) need to be fixed to fully determine its other properties? | |||
* What configuration maximises the perimeter of a rectangle? What configuration maximises its area? | |||
