This interactive smartboard lesson provides practice in making new words and changing words by adding the prefixes inter- and in- and the suffixes -ive, -tion, and -ess. Students have an opportunity to make words complete a sentence or story by adding the prefix or suffix or both to root words to change their meaning. Created for upper grade 4 and 5, but would be appropriate for grades 4-7 depending on the level of the class. All slides are self checking so it's easy to use as teacher directed in whole group or as independent student use in a center or station. The last slide is linked to a website with a movie trailer song and students will need to write as many words as they can within the time frame of the song.... Just a little fun competition before sharing their words with the class. Created with Smart Notebook 11.
