The
fox
jumps!
Try it together
Build a sentence, one word at a time.
Choose the words in the right order. Every word is a real button, so the activity works with a keyboard as well as touch.
Make: “The fox jumps over the log.”
Select a word to add it. Select it again in the sentence to return it.
Visual demonstration — not the live app
Handwriting practice
A clear path from sound to sentence.
Optional tracing gives a gentle starting point. Large writing boxes leave room to form each letter, while supportive feedback shows which letters need another try.
Children can tap letters to hear their sounds, then move between typing and handwriting when they are ready.
Confidence without pressure
Small steps. Calm feedback. A sentence they made.
The app keeps attention on one achievable action at a time. Parents choose the sentence and settings; children get the space to practise at their own pace.

2
Practise with support
