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