Magnetic letters are a great way for students to learn spelling patterns. Use these letters on cookie trays with Mr. Know-It's Letter Spells. Students put the magnetic letters right on top of the activities on the cookie tray.
For a real addition to your learning centers, look at the MagnaBoard and Magnetic Letter Set. It is used the same way as the cookie tray, but it is also dry erase.
