We know it may be surprising to see that the x card in your Pre-reader or Level 1 flash cards features a word ending in x when all other cards show a word beginning with the featured letter. Don't worry, this is intentional.
When we teach the x sound to new readers, we focus on the 'ks" sound of x, as in 'box' rather than the less common 'z' sound, as in 'xylophone'. Therefore, we feature words that end in this sound, such as 'fox' and 'box', so children can hear and practice this sound. On our newer flash cards, you'll see an asterisk and a small note: *Ending Sound, like below. The older packs (with red flash cards) do not include this note, but the rationale is the same.
