Adding -ING to the end of words can be a challenge for students. You can make it a little easier by introducing them to the rules on the worksheet titled "4 Rules for Adding -ING: Find the Correct Spelling of -ING Words."

It outlines four separate rules on what letters to look for and how to add -ING. The four rules are:

1. Add -ING if a word ends in WXY.

2. Double the last letter and add -ING for words with a CVC ending.

3. If a word ends in E, drop the E and add -ING.

4. Otherwise, just add -ING.

Below, a series of words are listed in boxes. Students must list the number of the rule the word follows. Then, faced with two options, they circle the correct spelling of the word with -ING. For example, for the word "know," students fill in Rule 1 and circle "knowing" (not "knowwing").

Learning how to write words with the ending -ING is important because it supports writing and reading skills but spelling them can be tricky. It's important for students to be able to learn the rules of adding -ING and practice the correct spelling for different types of words.

You can give students a list of rules, post them on the wall as you're learning -ING words, or add the rules to the beginning of a worksheet. Then, a worksheet could list words, and students could write the -ING version next to them.

You can also create worksheets that have students write the rule that they're following and circle the correct -ING spelling between two different choices. For example, students would circle "jetting" for the word "jet" (not "jeting"). Then they could state that they're using the rule that says you have to double the last letter before adding -ING for words that follow a CVC ending pattern.
