Sweet-Sweet Pythagoras Theorem
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.
Number of students: 40 students ....8 groups.
Rule:
- Fill the 3 × 3, 4 × 4 and 5 × 5 squares with candies. One in each small square.
-
Now take the candies from 3 × 3 and 4 × 4 squares then put it on the top of 5 × 5 square candies.
- Write down the pattern.

| 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:
- Find the relation between areas on the sides of the right triangle?
- How you can find the length of unknown side?



1: square of hypotenuse = sum of the square of the two legs
ReplyDelete2: by using the relationship and take the square roots
Interesting activity
ReplyDeleteWish 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 .
ReplyDeleteCollaborative learning helps student clarify ideas through discussion and increases student retention.Gud job👍👍👍
ReplyDeleteLove the idea! I am sure the hands on activity incorporated into the lesson was an amazing learning experience for your students.
ReplyDeleteInnovative way of proving pythagoras theorem. Well done ustadha
ReplyDeleteEffective learning. All students engaged with group work. Fantastic!
ReplyDeletevery intresting n clear explainations.well done
ReplyDeleteI've always have a special place in my heart for high energy teachers. I admire their enthusiasm and how they bring joy, laughter, and develop interest in the class. My best wishes for you.
ReplyDeleteThank you teacher
ReplyDeleteThanks teacher
ReplyDeleteHands-on activities always have a longer impact on students learning then direct teaching.Their energy is so visible during the activity.Good idea!!
ReplyDeleteWish you were my maths teacher when I was still in school :P
ReplyDeletevery nice
ReplyDeleteAmazing darling. The students wont forget this theory anytime soon!
