One of the strategies that can be used to engage students is cooperative learning. In Grade 7 math, we recently covered Combining Like Terms and instead of working individually through worksheets, the students collaborated with each other through an interactive activity.
The class made a large pyramid out of strips of coloured papers containing terms. They started from the bottom where all terms were aligned. Afterwards, they combined terms that are similar and wrote their answers on the strips of paper until they reach the top of the pyramid. This activity was adopted from https://mail.google.com/mail/u/0/#search/pyramid?projector=1 . The students enjoyed creating their group’s pyramid and it was interesting how different groups came up with different strategies on how they will divide their work so they can finish solving within the given time. This activity can also be used in other math concepts like integers, GCF, and LCM, among others.
