Reviewing the previous few worksheets if necessary, have the students try to organise the words provided into the three categories. Some words, like "on" have a place in both the 'time' and 'placement' columns. Give plenty of examples as they work through the words to make sure they understand them. Stop on any they find difficult and elaborate with more examples or demonstrations to make it clear.
At the end of this, they should be ready to compose three complete sentences, one for each type. Correct their sentences if needed then have them read them out loud.
