Morphology is a powerful tool for teaching older students both decoding longer words and understanding new vocabulary words. We use the suffix -est to turn adjectives into superlative adjectives.
In this lesson, you will teach students many things.
suffixes come at the end of words
suffixes change the meaning of a word
suffixes are not words, but they are units of meaning
we use the suffix -est to turn adjectives into superlative adjectives
sometimes we have to change the spelling at the end of the base word to add the -est suffix
there are some irregular superlative adjectives
It is helpful for students to know the parts of speech as they work on morphology. If your students need to work on parts of speech, I highly recommend this writing program. It teaches writing complete sentences based on parts of speech. If you need to, you can even use these two programs at the same time.
Teaching the Suffix -EST
To teach your students about the suffix -est, display the presentation below. You can access the presentation from this website for free. You can also purchase the slideshow for use at school.
This lesson teaches the function of the suffix, but it focuses on spelling because there are so many spelling rules for adding suffixes that begin with a vowel. At the beginning of each lesson, you will share the slide with the basic information and the chart that shows the different spelling patterns. Then, students will practice the spelling patterns using this routine:
You display an adjective from the presentation.
Students write the adjective with the -est suffix in their writing notebooks or on a whiteboard.
You display the adjective with the suffix -est from the presentation (the next slide).
Students check their work and get immediate feedback.
This is a spiral review lesson. Each day, you will teach students one spelling pattern for the suffix -est. Students will practice that pattern and review any past patterns. The complete lesson will take ten days. You also get mixed review for practice later in the year to keep your students fresh.
Check out this list of words with the suffix. You can use this list to build your own activities for your classroom. You can also get a printable .pdf.
