  Sweet-Sweet Pythagoras Theorem

A geometrical relationship between three sides of the Right-angled triangle. 

a2 + b2 = c2


Today the Geometry lesson in my class started with a lesson PYTHAGORAS THEOREM. They have a stressful week due to Monthly exams and soon they will have to work on their Math’s Project. So I decided to start with a group activity to develop their interest.
We started with an introduction to Pythagorean theorem and recall the names of the sides of the triangle that “the hypotenuse is the longest side of the triangle because it is opposite the largest angle. The "right angle” should be between the other two side[legs]. Used the white board to explain the rule
Activity started with grouping the students in to 8 groups. Max 5 students in each group. Students were given the two different flavors of (square shaped) Sugus candy and a chart on which the three areas (blocks of 3 × 3, 4 × 4, 5 × 5) on three sides of the triangle are drawn already. 



Material: Sugus candy, chart paper, ruler, pencil.
Number of students: 40 students ....8 groups. 
Rule:
  1. Fill the 3 × 3, 4 × 4 and 5 × 5 squares with candies. One in each small square.
  2. Now take the candies from 3 × 3 and 4 × 4 squares then put it on the top of 5 × 5 square candies.
  3. Write down the pattern.
After placing squared-shaped candies on top of squares of three sides 



after moving all the candies from both legs  and keeping on top of the candies on Hypotenuse ....here is the proof.
They really enjoyed this activity

Explanation of the activity and proof by a student




Assessment:

  1. Find the relation between areas on the sides of the right triangle?
  2. How you can find the length of unknown side?

    1: square of hypotenuse = sum of the square of the two legs
    2: by using the relationship and take the square roots

    Wish I had an activity back in my school days . Maths would have been a breeze then. A very simple and interesting activity for students to grasp the concept of pythogoras theorem .

    Hands-on activities always have a longer impact on students learning then direct teaching.Their energy is so visible during the activity.Good idea!!
