Explain to your child that most singular nouns become plural by adding "-s". E.g. "cat"->"cats". For words ending in "-ch", "-sh", "-s", "-x", or "-zz", add "-es". E.g. "buzz"->"buzzes". Then, get them to circle the right plural form of each noun on the worksheet.
Learning prefixes is key for effective communication. Help your child master re-, bi-, and un- with a Kids Academy worksheet. Ask them to go through each sentence, underlining words with one of the prefixes. This will help them appreciate how prefixes alter the meaning of a root word.
