In this objective, children will learn how to add the prefix in- and its assimilated forms im-, ir- and il- to bases and stems to form new words. Over six 20-minute lessons, they will:

·        Learn that the prefix in- carries the meaning “not” ·        Learn that when a base or stem begins with the consonant letters m, p or b, prefix in- is assimilated to prefix im- ·        Learn that when a base or stem begins with the consonant letter l, prefix in- is assimilated to prefix il- ·        Learn that when a base or stem begins with the consonant letter r, prefix in- is assimilated to prefix ir- ·        Explore a range of bases and stems that can fix to the prefix in- and its assimilated form ·        Learn that prefix in- can also carry the meaning “into or upon” ·        Explore the etymology of a range of bound bases ·        Complete sentences by adding the correct assimilated form of prefix in- to bases and stems ·        Build word sums ·        Sort bases and stems depending on which assimilated form of the prefix in- they would take ·        Reinforce learning with a practical game
