An idea for using twitter to crowd source answers to mathematical questions.
In a period of ten days you can ask each student to tweet one question relating to maths or science. The content of the tweet should be a picture (taken somewhere in the student’s neighbourhood) with a question. This way you can draw student’s attention to the presence and usefulness of mathematics in every day life.
a) What is wrong with this?
b) When corrected, how much (in percentage) did they lower the price?
Mathematics (vocational education): percentages, geometry, proportions,…
(activity made for students in adult education)
How to do it
Decide on a period of ten days with your students and decide on the topics to use.
Every student has to tweet (with #10daysofmathtweets) his picture with question within that period. He e-mails the correct answer to the teacher who checks this. Students have to send their answer to the teacher by e-mail within 24 hours. After the 24 hours, the student who tweeted the question may tweet the answer to his/her question. He also completes a document in Google Drive with the explanation (of the answer) of his question. That way a database of questions gets created that can be used for example as a way of preparing for a an exam about those topics.
The teacher puts a graph on the ELO so the students can see who’s getting the most correct answers.

If students want to edit the picture: Paint,…
Programme to make graphs: Excel,…
