Sentence Builder Tiles
Tap word tiles from the tray to build a sentence on the rail, checking word order as you go. A gentle red underline flags an invalid sentence, and a green check confirms a correct one.

How to play
- Type one correct sentence per line — punctuation like periods stays attached to its word — then tap Start Practice.
- Tap tiles in the tray below to add them to the sentence rail above, building up the sentence in the order you choose.
- Tap Check Sentence to see if the word order is correct: the rail turns green for a match, or shows a red underline and shake if it's not quite right yet.
- Tap Clear to reset the current round and try again, or Next Round to move on to the next sentence once you've got it.
Type in a handful of correct sentences and Sentence Builder Tiles scrambles the words of each one into a tray of tap-to-place tiles. Students rebuild the sentence one tap at a time on the rail above, tapping a tray tile to add it and tapping a rail tile to send it back if they change their mind. Tap Check Sentence and the rail glows green for a correct order or shows a gentle red underline with a shake if the word order doesn't match — no scolding, just a clear nudge to try again with Clear. Each line you type becomes its own round, so a whole worksheet's worth of practice sentences flows one after another, with a running count of how many the class got right.
Frequently asked questions
- What happens if a sentence has the same word twice, like "a cat sat on a mat"?
- Each word tile is tracked individually even when the words match, so repeated words like "a" never get confused with each other when you tap them onto the rail or send them back to the tray.
- Can students undo a tile placement if they tap the wrong word?
- Yes. Tapping any tile already on the rail sends it straight back to the tray, so you can rearrange freely before tapping Check Sentence — there's no penalty for experimenting.
- Does the tool grade grammar, or just word order?
- It checks that the tiles on the rail exactly match the order of the sentence you originally typed in, word for word. It's a word-order matching check, not a full grammar checker, so it works for any sentence you write.
