Fast finishers, part two: higher grades (9-15)

There are some activities that work with both lower and higher grades, such as:

1 write a riddle (using the template or cues)
2 write a book review
3 write a book recommendation
4 design a book cover (for the book you have read or the article you would make into a book)

Then there are activities that will take some time as they suggest creating a list/ a collection. Also, this is the type of work that pupils could put in their language portfolio. 

5 create the list of rhyming words
6 keep the list of things you are grateful for
7 generate a collection of jokes/ riddles/ quotes

If you want your pupils to extend the work on topic you are currently exploring, you may use these activities:

8 write more questions for the text
9 supply different ending
10 create a comic using the text
11 choose x words to look up in the dictionary and write down their meaning and an example sentence
12 create an acrostic poem using a word from the text
13 write a rhyming poem using at least x lines
14 make a T-chart of pros and cons of having/making/doing something

Finally, here are some ideas that imply using creativity/imagination.

15 brainstorm at least x creative uses of something for the future (e.g. creative uses of a plastic spoon)
16 imagine and illustrate a brand new type of transport/house/schoolbag etc.
17 create a new planet and describe (draw) people, clothes, house, food etc. (this may take a longer period of time but could be very interesting)
18 offer pupils to do independent research project using the table Questions I have/What I discovered/Sources 

While I am considering which activities to use, I thought it would be a good idea to take into account which thinking skills I would like to practice. 

Also, there is a question of how often I want to change activities. Do I write them for the term or for the month or for the topic? 

As the new school year is approaching, why not consider these?
