Changing a noun from one to more than one looks like a single rule until a student writes “boxs” or “two foots”. This course teaches the whole picture: the -s ending that covers most nouns, the -es ending for the words that need an extra sound, and the handful of everyday nouns that change shape completely.
It also heads off the apostrophe habit early. Students learn that more than one never takes an apostrophe, which saves a great deal of trouble later when possessives arrive.
What you will learn
- Add -s to make most nouns mean more than one
- Add -es to nouns that end in s, ss, x, ch, or sh
- Use the everyday nouns that change in their own way
- Choose the right form using clue words in the sentence
- Leave the apostrophe out when a noun means more than one
A note for parents and teachers: the irregular plurals in Lesson 3 sit slightly ahead of Grade 1 expectations. They are included because children use these words daily and produce forms like foots and mouses without them.
