Geometry, you mean geometry ?

BEFORE working on the perpendicular and parallel lines on paper and with pens, pupils started to work with legos. First, they used plates and pins and then they used their ruler, set square and the famous little bricks.

At the beginning of the course and to check their knowledge about perpendicular and parallel lines, they had to answer a quizz on the apply plickers which offered the possibility to see the proportion of good answers in the class.

Then, to train, they could do short exercices on pads with the apply evernote.

To finish, to explain to other pupils how to draw parallel and perpendicular lines, they realized tutorials.
