Pyramid - Recognising a pyramid and its net and calculate its surface area.

Students know the characteristics of pyramids and are aware of the differences between a pyramid, a cube and a cuboid.[br]Students know how the nets of squared pyramids look like.[br]Students can calculate the surface area of a squared pyramid.

[u]Lesson Objectives[/u][br]Studens elaborate a mathematical problem on their own.[br][br][u]Assessment[br][/u]Review of the task "model of a pyramid" by the teacher.

Sequence:[br][list][*]Introduction into GeoGebra (10 min)[br][br][/*][*]Students edit the worksheets in this book. ( 30 -50 min)[br](Starting with simple materials, since the students are not familiar with GeoGebra jet.)[br][br][/*][*]Next the students have to complete the task "model of a pyramid" (10 - 30 min)[br]Therefor they get one pyramid out of different models. [br]They have to measure it, make a graphic presentation, insert a suitable dimensioning, describe the pyramid and calculate its surface area. This task will be done during the lesson and will be evaluated by the teacher. [br]Practical relevance and the use of suitable measuring instruments are importent in this task.[br]Questions can be answered individually.[br][br][/*][*]Opportunity for differentiation: [br]additional models (f.i. pyramids with different bases)[/*][/list]

This lesson plan can be used for students with no or little experience with GeoGebra,[br]since there is hardly any prior knowledge needed.[br]The worksheets are simple and self-explanatory in usage.[br]Students who have already had computer lessons, should not have problems with this technology setting.[br][br]If there are problems with this technology setting anyway, you have alternative options:[br][list=1][*]Team teaching: A second teacher can help to support students individually.[/*][*]Plenum: Worksheets that are to hard can be discussed with the whole class. Therefor the projector should be used.[br][/*][/list]
