About this resource

What's inside this resource

If you want to give students extra practice with adjectives, I have just the resource for you.

What You Get:

This is an Adding –er or –est Worksheet that was designed for elementary students who are working on or have mastered this skill. It also works well as a review for students. It is a 3-page printable.

How To Implement This Resource:

You can print off enough copies of the worksheet for each student to have. You may also choose to print only a few copies and laminate those. If you choose to laminate them, students can use dry erase markers to solve the problems. This is a great activity to place into a reading center or small group activity.

The Adding –er or –est Worksheet consists of 4 charts and 4 short answer problems across 3 pages. For each chart, students will follow the rules to add the correct ending to the adjectives included. On the last page, students will be able to make sentences with the adjectives.

I hope you enjoy!
