A moment to study

Step 1)

Together with your neighbour choose of the following paragraphs:

2.1 - 2.2 - 2.3 - 2.4 - 2.6

Step 2)

Study this paragraph for the coming 10 minutes — done, start studying paragraph 2.5 and do the yellow block exercises.

Step 3

After the 10 minutes are over, together with your neighbour come up with two test questions about this paragraph. Write them down.

For next lesson

• Read paragraph 2.5
  
• Do the yellow block questions of paragraph 2.5
