Math Snacks: Learning Expressions with Creativity through Sunburst & Agrinautica

Log in to save this to your schedule and see who's attending!

Limited Capacity seats available

Agrinautica is a new computer-based game, part of the already existing Math Snacks suite of learning materials. Math Snacks Early Algebra focuses on student understanding of early algebra concepts as they relate to the Common Core State Standards and Mathematical Practices. Early algebra is an emerging term in math education research (Lins & Kaput, 2004) focused on the introduction of algebraic thinking in the elementary grades. The main key concept address in this session is writing and interpreting numerical expressions.

-Participants will explore the following key concepts:
-Comfort with the notation and syntax of expressions
-Facility in reading, writing, and interpreting numerical expressions
-Utility in writing an expression to represent a specific numeric value
-Understanding that when there is more than one operation, order matters
-Experience mathematics as something that can be explored
-Ask questions and make conjectures
-Practice and reinforce simple mental math

Participants will begin by having a general discussion on what students may know or not know about writing numerical expressions. In groups of 4-5 people, they will engage in a bonus hands-on activity. The Sunburst activity is designed to get students thinking about different ways to use the four operations to compose a number. For example, the number 12 can be expressed as 36 divided by 3, and (13 + 2) – (1 + 2). The goal is to increase the use of parentheses and operations to make the sunburst as big as possible. They will then use their laptops (or our iPads) to access the game. Participants will play Agrinautica for 20 minutes to create bright, beautiful plants on the screen by using parenthesis, operations, and digits 1 through 9. The more complex their expression becomes, the bigger and brighter their plants will be. For example, to create the plant Azirium, users will need three types of operations and two sets of parenthese
