This set focuses on the way words change when the endings s, ed, ing, er, and est are added to them to form plurals, verb tenses, and comparatives. The word without the affix is shown on one side of the card, and the word with the affix on the other, giving children an easy way to learn about and practice spelling with word endings. Word Sorting Kits provide a mind-stretching way to help children look for and remember patterns in the ways words are spelled. In so doing, they will develop spelling proficiency, word analysis skills, and much more. Carefully planned activities call for students to sort words into groups that share common patterns. They will then compare and contrast word elements, form concepts and generalizations about how words are spelled, then transfer their understanding to new words that share the same patterns. All sorting activities are developmentally sequenced and move from easier, more common spelling patterns, to more difficult ones. Sturdy Word Sorting Cards measure 3" by 1 1/2", and come packaged in a storage box with tabs to keep everything organized and easy to use. Cards can also be used with our custom pocket chart for demonstration. 142 Word Cards, 19 Label Cards.
