What is it?
Who doesn't love a bit of tick-or-trash? Designed to encourage students to reflect upon and correct common errors, this standard form activity comes with a twist. Rather than just tick-or-trash, there’s now a third option – improve.
Pupils work their way through the sheet, stating whether answers are correct, incorrect or can be improved upon. Adding this extra degree of complexity forces learners to identify and challenge their own misconceptions, helping to promote a deeper understanding of the topic.
How can it be used?
Pupils need to be comfortable with the basics in order to reap the benefits of this exercise, so I’d suggest using it as an end-of-a-topic activity, or as part of a homework task. Otherwise they may not be able to identify the incorrect methodologies, which could lead to further misconceptions.
Why restrict this exercise to standard form? From fractions to algebra, this worksheet can easily be adapted to suit a variety of topics. The possibilities are endless!
