Topic
Exploration, derivation and practice of the area formula to calculate the area of a kite.
Learning Outcomes
Students know the properties of a kite and they use this to derive the area formula of a kite.[br]They understand the derivation and can apply the formulas to calculate the area.[br][br]
Lesson Objectives and Assessment
[u]Lesson Objectives[/u][br]Students know the properties of a kite.[br]Students can explain the derivation of the area formula of a kite.[br]Students are able to calculate the area of kites, rhombuses and squares.[br][br][u]Assessment[/u][br]The students have to present their calculations and give feedback to each other.
Teaching Strategies
Introduction:[br]The teacher explains the content, the sequence and if applicable the use of technology in this lesson.[br][br]Main Activity:[br]The students explore and practice the calculation of a kite in their own speed by using a computer.[br]Therefore they work on the worksheets in the second chapter of this book. [br][br]Conclusion:[br]Every student gets a copy with different kites and they have to calculate the areas on their own.[br]Then they present their result to a partner and give feedback to each other.[br][br]
Technology Integration
Throughout the lesson computers or tablets are needed and the students work independently on the GeoGebra worksheets.[br]It is advantageous if the students are familiar with working with GeoGebra worksheets.
