Consonant Trigraphs


Consonant Trigraphs introduces students to make of the trigraphs in English. Students will be able to identify and spell words that contain these trigraphs.

There are many suggestions listed in the “Options for Lesson” section on the classroom procedure page. One option is to assign a single trigraph to pairs of students. Print copies of stories that the students can use to circle the trigraphs they were assigned. Another suggestion is to conduct a “trigraph bee” in which students name the trigraph used and spell the word. You could also give students a dictionary that they can use to find the trigraphs they learn about in the lesson.

What our Consonant Trigraphs lesson plan includes

Lesson Objectives and Overview: Consonant Trigraphs teaches students how to use trigraphs. Students should already know about digraphs, so this lesson should build on their previous knowledge. The lesson describes several common consonant trigraphs in the English language.

The content page in this lesson first describes a few digraphs that students already know. These include SH, CH, PH, TH, NG, and WH. After they review this concept, students will learn the eight most common consonant trigraphs in English. It also points out how most of these trigraphs except for TCH appear at the beginning of words. This piece of knowledge will help them later when figuring out a word based on a picture.


Students will work with a partner for the activity. However, you can assign them to groups or have them work by themselves if you prefer. Students will create a poster that shows each of the consonant trigraphs. They will need to add drawings and pictures or images from the internet that relate to the trigraphs. There are eight trigraphs in the table on the worksheet that they will need to cut out. They will decorate each one and glue them onto their posters. They will add the relative drawings and images below the proper trigraph.


There are two sections on the practice worksheet. For the first section, students will read through 15 sentences. A word in each sentence is missing a specific trigraph. Students must to use the list of trigraphs to figure out how to finish the incomplete words in each sentence. On the section section, students will use the same list of trigraphs to finish eight incomplete words.


The homework assignment requires students to look at 16 pictures. They will need to figure out the word that represents each picture. Each word will contain one of the trigraphs they learned about during the lesson. While there may be multiple words that describe something, the correct word must contain a trigraph.
