Mouth position for /ks/

Say /k/ and /s/ quickly together: /ks/. It is like a tiny kick followed by a hiss. Listen for it at the end of fox and box.

Ways to practise the /ks/ sound

Explain that x is a sneaky letter that likes to hide at the end of words. Say box slowly: b-o-x, then just the end, /ks/. Make a kicking movement for /k/ and a hissing sound for /s/. Then go through the pictures and listen for the /ks/ at the end of each name, not the start. Page 2 lists all the names.

Extra x words

Box, fox, six, mix, wax, fix, taxi, relax.

Tricky bits

Words like x-ray and xylophone start with the letter x but sound different (/eks/ and /z/), which is why they are not used here. The end sound /ks/ is the one children need for reading words like box and six.

Game: Fox in a box

Draw a fox on a card and hide it in a box. Say words aloud: when a word ends with /ks/ (box, six, mix), your child opens the box to find the fox. If not, the box stays shut.

Little and often

Six o’clock, boxes in the cupboard and mixing a cake are good times to say a clear /ks/.

A silly sentence to try

The fox in the box has six socks.

Letter X sound questions

Why is the x page about ending sounds?

Very few words start with the /ks/ sound. In early reading, x mostly appears at the end of words like fox, box and six, so that is what children need to hear.

What does x say in x-ray?

In x-ray, the letter x says its name, “ex”. In xylophone it says /z/. These are unusual, so they are left for later.
