Concept DevelopmentToday 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 we add “s” at the end to make it

plural.Ex. t + s = toys

vowel and a y,

oy

Non - examples

book + s = books

car + 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 we drop the y and add “ies” to make

the word plural. Ex. strawber + ies = strawberries

consonant and a y

book + s = books

car + s = cars
