This first resource is usually how I introduce how to rearrange equations with a high prior attaining group. Different types of equations are introduced and each one is carefully modelled before giving students opportunity for independent practice.
During the assessment phase I usually get students to hold a fist to their chest so no other students can see & hold up one finger for “A”, two for “B” etc; this lets me immediately check if the students have understood & if they’re ready to move on.
This next resource is one of my usual “ramped” worksheets, differentiated in difficulty. As such, this is suitable for a mixed ability group (using the equation triangle instead of algebraic manipulation can be used)
