When students learn the patterns and structures of words they become word wizards! They are able to more fluently convert a word from one part of speech to another, adjust the meaning, or translate a word from singular to plural (or vice versa). In this set of activities students will build on their knowledge of word structure and practice adding prefixes and suffixes, changing tenses and using contractions.

This unit not only builds students' vocabulary, it also enables students to explore how words are related, in meaning, sound and construction. Learners will also discover some of the ways words are constructed using derivational root words, prefixes, suffixes, and compound words. Students will also learn strategies we use to shorten words and phrases like acronyms and abbreviations.

Multiplication is essentially repeated addition, or growing numbers by doubling, tripling, quadrupling, and so on. This unit presents mental models and strategies that help students learn and review the concept of multiplication. Students explore multiplication using arrays, partial products, doubling methods and the standard algorithm to solve numerical and word problems. Students will multiply whole numbers and simple decimals by base ten exponents (i.e. .3 x 103).
