Right Angles and the Pythagorean Theorem

Vocabulary: Pythagorean Theorem, right angle, hypotenuse, legs, square root, square, factors, prime numbers 

Day 1: 

• Read "What's Your Angle, Pythagoras?".   Use the following link http://roymath.weebly.com/uploads/1/1/2/7/11275399/6_-_whats_your_angle_pythagoras_booklet.pdf (if a group you can have student break up into smaller groups and read together or you can do as a read aloud)
• After reading the book student(s) will complete the worksheet "What's Your Angle, Pythagoras?" using media of the student's choice. Discuss with the student their answers to ensure understanding.

Day 2: 

• After reviewing with the student the Pythagorean Theorem (a2 + b2 = c2) and reviewing the sides or a right triangle (base, perpendicular, hypotenuse, the little box represents a 90 degree angle) explain to the student that you will be working together to solve for the length of the hypotenuse of a right triangle.  Using the "Pythagorean Worksheet" solve problem number one together with the student.  (see answer sheet for solution).  For ease of the lesson the student can use a calculator to figure out the squares and square root of numbers.  If the student is confident have them complete the worksheet using the student's choice of media.  
• If time permits, the teacher can move on to solving for a third side of the triangle (not the hypotenuse).  It time does not permit this can then be done on Day 3.  Attached are additional worksheets  Pythagorean Worksheet 2 and Answer sheet for solution.
