About This Lesson
A Tarsia activity by Alan Catley. A great way of introducing the Factor Theorem but it took a long time to ensure that this is a unique solution! i.e. (x-1) is only a factor of one of the given functions etc. A wonderful group activity used in conjunction with a paused slow plot of y = 2x³ + x² – 4x – 3 on Autograph (at approx x = -2) “where does this graph cut the x-axis?” etc. The group will have to share the work out which means they discuss and share each other’s answers but the more they do the easier the puzzle gets. The ‘Start’ is a trivial one deliberately!
A superbly challenging tarsia activity based on the topic of Factor Theorem. This resource could be used the main activity in a lesson. I definitely recommend this being a paired/grouped activity. Instructions supplied.
