Four sets of magnetic tiles to teach prefixes and suffixes. Add the prefix dis and the suffix y to the root word cover, and what do you get? Discovery! This set of magnetic prefix, suffix, and root word tiles lets children build big words, and discover that longer words are made up of smaller, recognizable word parts. A single root word can be used to create as many as 40 words! All together, these word tiles let you make hundreds and hundreds of words. Many word part combinations are so easy to read that even the youngest readers will be able to build bigger words, while better readers can build more complex ones.
