LISTENING

 

9. Listen and underline the stressed syllable in each of the following words:

rectangle triangle cylinder line
rectangular triangular cylindrical linear

Listen to the text and answer the following questions.

1. What is a 3-D object?

2. How are 3-D objects created in design?

3. What science is concerd with 2-D objects?

4. Where can you find 2-D objects in nature?

5. How is a 3-d object different from 2-D one?

Listen to the text again and fill in the gaps.

3-Dimensional, 3-Dimensional, this means the shape or something has 1)_____ dimensions that means a curves up and 2)_____, side to side and front and ­­­3)_____ . That is 3-D. The opposite would be 2-D. So on the 4)_____ screen everything is 2-D. This is up and down and side to side. For 3-D you need 3-D 5)_____ for depth perception.

 

SPEAKING

12.Work in small groups; name the things which are usually round, triangle or square.

13.Imagine that you are a professor preparing for a lecture on Geometric Figures and Shapes. Think about the main ideas that you would like to cover in this lecture. You may also use the information from the text.

WRITING

14. Imagine that you are an examiner and you have to prepare some questions on the topic «Geometric Figures». Read the text again and use it to make a list of questions the students will have to answer at the exam. The following opening questions may help you.

- What is the difference between the …?

- How can we calculate the area/perimeter of …?

- How many straight/curved sides/angles …?
