Students can create an order of operations poster were they have a particularly complex problem that requires them to break down the equation into smaller pieces (decomposition of the equation). An example question could be: 2 + 3² – (8 x 2) ÷2.
Students would need to break down the equation to follow the order of operations. Students could also explain how this is a process of decomposition, as they are required to take a large equation and complete small parts in order to come to the correct answer. The audience would be their peers in the classroom (Grade 7/8) or perhaps a younger class group (Grade 5/6) who were going to be introduced to this concept for the first time.
