**Description**

General aims

Student will be able to explain how Pythagoras theorem works, how to use Pythagorean theorem to find right triangle side lengths.

Student will be able to solve basic mathematical problems connected with Pythagoras theorem. He will know basic vocabulary in English connected with geometry. Student will develop positive learning habits such as organisational and problem-solving skills.

Linguistic aims:

- to read English with ease

- to understanding content

- to communicate reading experiences

- to learn from written texts

- to master tools for gathering information

- to express understanding and experiences

- to enable students to understand topic correctly

- to develop academic language

- to translate words connected with Pythagoras theorem in English into the mother tongue using one’s own words.

Subject specific aims:

- student can explain how Pythagoras theorem works

- student is able to use Pythagoras theorem in math problems which are connected directly with a right triangle

- student knows how to name the longest side of right triangle

- student knows how to convert written sentences to mathematical sentences

- student gains confidence in their math skills

- student has unlimited access to free educational content one can master at their own pace

- student is better prepared for standardized testing.

Target group age:

Students from primary school (13-14 years old), before using the resource they need to know how to do basic operation with powers, roots, solve equations. Students also have to be familiarized with basic geometry. What is more, this video can be used by anyone who wants to know more about Pythagoras theorem, also by grade teachers who wants to teach math bilingually.

Level of competence in English (CEFR)

B1/B1+

Time required to use the resource with the students:

The teacher can use the resource with the students for one lessons. Video lasts 10:45 minutes.

How to use it

Before using the video during one’s classes, the students should be able to do basic operation with powers, roots, equations and know basics of geometry.

The teacher asks students to watch the video and does pauses in certain moments to give students opportunity to make notes, ask questions and develop some problems presented in the video.

During lessons the teacher should ask the student some questions in English, for example:

“How many degrees has an angle which we define as a right angle? ”

“What kind of triangle is a right triangle?”,

“Which side of right angle is called hypotenuse? ” “How can I tell which side is hypotenuse?”

“What is the Pythagorean Theorem in your own words?”

“How to solve hypotenuse?”

“How to figure out one side of the right triangle?”

“How to simplify square root?”

The students give the answers with the examples. The teacher should give them feedback and show students more examples on the black table. The teacher highlights some new words for students in English and students should find the translation these words into the mother tongue and write down the new words in English in the notebook with the right translation in their own words. The words which should be taken into consideration are: right angle, right triangle, hypotenuse, square root.

The teacher gives examples how to use Pythagorean theorem to find right triangle side lengths. Students practice it in small groups. Teacher motivates students to practice this lesson themselves on KhanAcademy.org as there are some links given with the video.

Possible difficulties for the students

Students who have poor knowledge of English can have problems with understanding the content. Students who has problems doing basic geometry and operations with powers and roots or solving equations can face difficulties in solving math problems with the Pythagorean theorem which are introduced in the video which is recommended.

**Comments**

The resource provides interesting self-directed learning, it can be used by teachers as a model to help them teach their own students how to do use Pythagoras Pythagorean theorem to find right triangle side lengths using English. The strength of the video is a simple language, visuals, clarity of explanation, many examples, intelligent software, deep data analytics and intuitive user interfaces. It presents an easy way to remember the steps for solving math problems connected with the Pythagorean theorem and uncluttered, understandable strategies which are easy for students to remember and for teachers to teach.
What is more, in the description to the video there is a link where one can practice this lesson oneself on KhanAcademy.org. and has free educational content which can master at one’s own pace.
In my opinion this web site is scientifically reliable and can be recommended to students and teachers, it is intuitive and usable. A layout is focused on ease of use. Consistent design allows the user to focus on the message. The resource could be more visually appealing to students. The drawback can be fast speech pace.
