Concept Development Today we will be working with words that end with a y to write them in their plural form. Ex. lady boy daisy There will be two types of plural forms. Some will be regular plurals and others will be irregular plurals.

A regular plural is a word that you add an “s” to at the end. When words end in a vowel and a y, we add “s” at the end to make it plural. Ex. t oy + s = toys

Non - examples book car + s = books + s = cars

Checking for Understanding TPS – Why did I just add an s to tray to make it plural? tray + s = trays

Irregular plurals are words that are not typical, usual, or common because they change spelling when talking about more than one. When words end in a consonant and a y we drop the y and add “ies” to make the word plural. Ex. strawber ry/ + ies = strawberries

Non - examples book car + s = books + s = cars
