Prior to this objective, teachers should assess the suggested morphemes for a recount – letter using the provided materials. If learning is secure, proceed to prefixes com-, con-, co-, cor-, col- objective; otherwise, refer to resources for additional support on suffix -ed, suffix -ing, suffix – ly suffixes -er and -or (Y2), prefix trans- (Y3) and suffix -ate (Y4).

Learn where assimilation of the prefix com- occurs
Explore a range of bound bases that take the prefix com- and its assimilated forms
Apply learning of the assimilated forms of the prefix com-
Solve word sums by combining morphemes and applying suffixing rules
Use matrices to build a range of words
Reinforce learning with practical games
