Proofs of the Pythagorean Theorem
The lesson plan was good organize and was cover all levels of students , timing in each activity was perfect starting from the assessment task , then assessment students response , there was suggested questions was helpful , there was some activities to support students , the discussion with the whole class at the end of the lesson was successful , power point also was clear the idea for most of the students. but not for weak students.
Finally, we need to develop some new recourses to support the applications on Pythagorean Theorem.
