This 5-day project-based math resource applies math concepts in a real-world scenario to teach students about **the properties of multiplication, including the associative property, distributive property, and commutative property**. In this** 5-day unit**, students will learn about and apply the properties of multiplication as they create and design cookies for a class cookie decorating contest. This multiplication 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 rounding and is **aligned with the following 3rd Grade Math Common Core State Standards:**

- Understand properties of multiplication and the relationship between multiplication and division.
- CCSS.MATH.CONTENT.3.OA.B.5

Apply properties of operations as strategies to multiply and divide.2¬†*Examples: If 6 √ó 4 = 24 is known, then 4 √ó 6 = 24 is also known. (Commutative property of multiplication.) 3 √ó 5 √ó 2 can be found by 3 √ó 5 = 15, then 15 √ó 2 = 30, or by 5 √ó 2 = 10, then 3 √ó 10 = 30. (Associative property of multiplication.) Knowing that 8 √ó 5 = 40 and 8 √ó 2 = 16, one can find 8 √ó 7 as 8 √ó (5 + 2) = (8 √ó 5) + (8 √ó 2) = 40 + 16 = 56. (Distributive property.)*

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

**What’s included in this resource:**

**Background Knowledge:**Using a KWL, students will build background knowledge around cookie decorating contests and learn about the judging criteria.**Multiplication Review:**Students will review the basics of multiplications and arrays.**Associative Property:**Students will learn about the associative property and practice solving equations using the associative property. The students will then create a cookie for the decorating contest and apply the associative property in their design.**Distributive Property:**Students will learn about the distributive property and practice solving equations using the distributive property. The students will then create a cookie for the decorating contest and apply the distributive property in their design.**Commutative Property:**Students will learn about the commutative property and practice solving equations using the commutative property. The students will then create a cookie for the decorating contest and apply the commutative property in their design.**Wrap Up:**Students will plan and review their final design for the class cookie decorating contest.**Optional Extension:**Students can create a model of their cookie using real cookies and decorating supplies to enter into a real class cookie decorating contest.
