X Words for Kids

Welcome to this list of x words for kids! This list contains both words that start with the letter x and words that contain the letter x so you can use them for letter of the week activities, reading centers, and more. The words are grouped by x words for preschool, x words for kindergarten, and x words for elementary students/older children.

Teaching the letter is is always tricky because there are few common words in the English language that start with the letter x. That’s why I frequently include words that contain x in my letter themed printables. If you’re teaching the letter x, be sure to grab these additional freebies:

What sound does x make?

Teaching the sound letter x makes in English can be challenging!

The most commonly used sound for ‘x’ when teaching kids is the /ks/ as in box. This is one reason why it’s popular to use words that end in x when teaching kids the letters x sound.

Because English is complicated, the letter x also makes other sounds. (In some other languages, like Spanish, letters make just one sound.) Other sounds of x include: /gz/ as in exam, /z/ as in xenon, /k-sh/ as in complexion, and /e-ks/ as in x-ray fish or extra.

Letter x words for preschoolers

Teaching the letter x to preschoolers usually focuses on words that make the “x” sound. This means you’ll mostly work with short words that contain or end with the letter x. Here are some common preschool letter x words and simple sentences to help you use them in context:

Ox – An ox is big.
Fox – The fox is red.
Box – The box is brown.
Axe – He has an axe.
