How to Teach Letter X

Say the sound first

Say /ks/ slowly, 3–4 times. Then say the keyword: "fox". Ask your child to repeat it and hold up a finger each time they hear the /ks/ sound.

Write the letter

Trace uppercase X and lowercase x in the air, on paper, or in sand. Say the sound each time. Kinesthetic practice helps letter-sound connections stick.

Read the beginner word list

Work through the beginner words above one at a time. For each word, blend the sounds aloud: "b — o — x".

Play an I Spy game

Look around the room for objects that start with X. Take turns — "I spy with my little eye something beginning with /ks/..." This builds phonemic awareness and makes learning fun.

Practice CVC words

Use the CVC word list above to practice blending. Write a CVC word, cover the last two letters, reveal them one by one, and ask your child to blend the sounds into a word.

💡 Quick tip for parents & teachers

When a child struggles to recall a sound, always refer back to the keyword: "What does X say? Think of 🦊 fox!" Associating the letter with a vivid picture word is one of the most reliable memory anchors in phonics instruction.
