Teacher's field guide

What Students Need to Do: Students spot familiar parts added to the beginning or end of a word. They explain how un- changes happy to not happy, or how -s changes cat to more than one cat.
What Mastery Looks Like: A student matches cat and cats to pictures of one cat and several cats. They can point to the added -s and tell what it means.
Common Misconceptions: Students may think cats still means one cat because cat is still in the word. They may read unhappy as happy and miss that un- changes the meaning.
How to Assess It: Show happy and unhappy face cards and drawings of one cat and three cats. Ask students to match the words to the pictures and explain what un- and -s mean.

Lesson moves

Give pairs paper cards marked un, happy, cat, and s; have them build words and match each one to a drawing.
