Walls of Words is another fabulous site for practicing sentence building with students.
You can choose between a 5 word or 7 word sentence.
You are then given a set of words and your job is to unscramble
the words to make a complete sentence and add the
correct punctuation before the timer runs out.
If your sentence is correct the builders will come out and
help you finish the wall and you'll get a new set of bricks.
