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