Instructions: Work through each short activity and read every word carefully. Use the examples and word bank to help you spot spelling patterns, choose the correct homophone and place apostrophes accurately. Check your answers by rereading each completed sentence.
Choose the correct word ending
Look at the word beginning and the clue in brackets. Write the complete word, choosing the correct ending: -tion, -sion, -ssion or -cian. Example: act + (the result of acting) = action.
1. invent + (the process of inventing) = inven___
2. decide + (the result of deciding) = deci___
3. discuss + (the act of discussing) = discu___
4. music + (a person who plays or writes music) = musi___
5. collect + (the act of collecting) = collec___
Build words with -ous
Add -ous to each word beginning to make an adjective. Use the clue to check the meaning. Remember that the spelling sometimes changes when the suffix is added.
Example: danger + -ous = dangerous
1. A person who has lots of courage is courag___
2. Something full of fame is fam___
3. Something that causes danger is danger___
4. Something with lots of variety is vari___
5. A person who is full of mischief is mischiev___
Who owns these things?
Rewrite each phrase to show that the plural owners possess the item. Add an apostrophe in the correct place. Example: the coats belonging to the girls = the girls’ coats.
1. the toys belonging to the boys
2. the nests belonging to the birds
3. the lunches belonging to the children
4. the hats belonging to the ladies
5. the books belonging to the pupils
