This is a Clilstore unit. You can .
You will learn about the importance of the Pythagorean Theorem in the video above.
Remember that, to implement the Pythagorean Theorem, a triangle has to be a right-angled triangle.
The longest side of a right-angled triangle is always opposite to the 90-degree angle (right angle). It is called the hypotenuse.
The other 2 adjacent sides are called the legs of the triangle.
Pythagorean theorem states that the square of the hypotenuse of a right angled triangle is equal to the sum of the squares of the other 2 sides.
1- Whatch the video "Pythagorean theorem explained" (here you have the transcription):
2- Now watch the "Pythagorean theorem water demo", a very useful example which illustrate how the theorem works. Then, do the following tasks:
- Activity 1: use the sliders to explore the Pythagorean theorem (work in pairs)
- Activity 2: do the Hot Potatoes Match and check the solution (work individually, then discuss with your partner and finally check the solution)
- Activity 3: listen to the Pythagorean song. Try to identify the key words (at the end of the unit you have the lyrics but first listen without reading them).
- Activity 4: listen again to the Pythagorean Theorem explanation and then fill in the gaps. After that, compare your answers with your partner's and finally check your rights and wrongs (remember you have the transcription above but try to fill the gaps firstly without looking at it)
- Activity 5: solve the problems (write the septs down in your notebook, work in pairs).
- Activity 6: Play to the Pythagorean games (play two-on-two). You can also play alone whenever you want.
- Closure activity: Invent a problem in which you need to use the Pythagorean Theorem to get the solution. Include realistic mesures, units, etc.
PYTHAGOREAN SONG LYRICS
Look at a right triangle
With a 90 degree right angle
Across from the right angle is the hypotenuse
It's no surprise the hypotenuse is the longest side
Now how do you find the hypotenuse's length
If you know the length of the two other sides?
Let's take you back to ol' Ancient Greece
Pythagorus is gonna show you why:
a squared plus b squared equals c squared
Where c is the length of the hypotenuse
a squared plus b squared equals c squared
Where a and b are the length of the other sides
The Pythagorean Theorem
Is a delicate calculation
To find the hypotenuse take the square root
Of the sum of the two other sides' squares...and then compute
How do you find the hypotenuse's length
If you know the length of the two other sides?
Let's take you back to ol' Ancient Greece
Pythagorus is gonna show you why:
a squared plus b squared equals c squared
Where c is the length of the hypotenuse
a squared plus b squared equals c squared
Where a and b are the length of the other sides
