Expand and Simplify (Spot the Mistake Worksheet)
Spot the mistake activity can be used to assess pupils understanding of each topic.
This spot the mistake involves expanding and simplifying brackets. The worksheet given has an already matched up tarsia puzzle and pupils are told there are mistakes to be found.
Pupils should then work through the matched up edges to check, by doing the expansion themselves, if it is correct. If correct shade in one colour (I use green), if it is wrong pupils shade it in red and then list the correct answer in the space provided.
All our resources come complete with instructions and ideas to stretch and support pupils.
