In this 5th grade division unit, students will take their understanding to the next level by applying division skills with multi-digit numbers. Students will also begin to explore division with decimals and practice using estimation to check the reasonableness of their answers. Last, students will use their knowledge of the base ten number system to divide decimals by base ten exponents (i.e. .4 ➗ 104).

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).

Words work together in a sentence, each one performing a different task. By fifth grade, students have become more adept readers and writers and they are familiar with the basic parts of speech. The activities in this unit revisit some of the basics and also add depth to their existing understanding. Students will engage in such topics as superlative adjectives, correlative conjunctions and prepositional phrases, to name a few.

Sentences are the building blocks of paragraphs. A sentence is a complete thought that can stand alone and in this unit students will learn what comprises a complete sentence and how to identify a fragment, or incomplete sentence. They will explore different kinds of sentences and how to punctuate them. And, to sharpen their craft, students will learn how to spice up their own writing by adding sentence pattern variety.

Letter writing is a very engaging and authentic way to learn formatting, punctuation and grammar. The activities in this unit should be learned in tandem with actual letter writing to aunts, uncles or other special far-away people. That way, students can learn and practice the letter writing skills and then apply them in their own letters. It would be especially rich to include their thoughts about books they are reading.

Writing reports and other kinds of informational pieces is a skill unto itself. It requires an understanding of organizing and sequencing thoughts, tying them together in a way that makes sense to the reader and sometimes a bit of research. It is recommended that students participate in writing their own informational essay on a topic of their choice. This will allow them to apply all that they are learning through the exercises in this unit.

A sentence stands alone to express a complete thought. Surprisingly, most 5th graders still need to revisit the concepts of complete sentences and fragments and how to punctuate the four different kinds of sentences. Combining shorter sentences into longer, more complex sentences is another skill that requires practice. Students get all of that needed review in this unit, in addition to learning how to identify and fix run-on sentences.
