This 5-day project-based math resource applies math concepts in a real-world scenario to teach students about **solving two-step word problems with unknown quantities**. In this** 5-day unit**, students will solve multi-step word problems including all four operations (adding, subtracting, multiplying, and dividing) to figure out information that they need in order to open their bookstore. This multi-step word problem math project is engaging and authentic. Plus, it’s available as both a digital and print resource.

This project-based math resource covers concepts of addition, subtraction, multiplication, and division in multi-step word problems with unknown quantities and is **aligned with the following 3rd Grade Math Common Core State Standards:**

CCSS.MATH.CONTENT.3.OA.D.8

- Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

**This resource is available in both Printable & Digital Google Slides versions.**

**Note: **While this resource is aligned with third grade Common Core standards, it is a challenging resource and should be used toward the end of the year or as review with older students. Some word problems may have three steps instead of two.

**What’s included in this resource:**

**Background Knowledge:**Using a KWL, students will build background knowledge around opening a bookstore.**Word Problem Concepts:**Students will review words that indicate the type of word problem they’re solving: addition, subtraction, multiplication, or division.**Two-Step Word Problems:**Students will learn the steps to follow for solving multi-step word problems.**Unknown Quantities:**Students will learn that letters can be used to represent unknown quantities in a math equation and write equations using a letter to represent the unknown quantity.
