4. Step 1. Solve the problem. Using the
Internet find what the answer means in
your school‘s history. Work in pairs.
One day a grocery shop sold 250 kilos of potatoes.
Another day they sold 20% more of potatoes. On

6. Step 3. Find one more important date in
your school‘s history on the Internet
and create a problem. It can be either a
word problem or an arithmetic problem.
Make a slide with the problem and its
solution. Work in pairs.
7. Revise the two dates.
Students present the dates and events which they
used while creating their problems.
