About This Lesson
A Collective Memory activity on Grouping Symbols and Simplifying. This one contains missing answers and a deliberate mistake! Thanks to Melanie Gilbert for this one! For more information and ideas about how to use this resource, and links to my full index of Collective Memory resources, please visit http://www.mrbartonmaths.com/collectivememory.htm
Another activity from this excellent series. This like the other activities helps with concentration and memory skills. So often students understand work well but do have problems remembering facts such as these. Regular review with an activity such as this should help. Research on memory suggests this is the case.
