Building Rational Number Sense through "The Grapes of Math" and More!

During this session, participants will be engaged in open-ended problem-solving tasks which develop rational number sense. Participants will learn how to translate story-book pictures as well as pictures of the world around them into meaningful mathematical tasks that involve fractions, operations with fractions, ratios and proportions, which are appropriate for students in grades 4th - 7th. Participants will leave with a variety of activities that can be implemented immediately.

What Are Prime Numbers? How Can They Help Students with Fractions?

Part 1: Numbers falling between times table products are helpful because they do not have multiple factors. Come see how 4th-6th graders strengthen understanding and reasoning power regarding primes, factors, multiples, and fractions. [Part 2 extends to GCF, LCM, repeating/terminating decimals.]

The Arc of Arithmetic to Algebra (V)

**Speakers** *EP*
## Elizabeth Peyser, National Director of Content and Implementation

How is “subitizing” connected to algebra? Join us to investigate the coherence in the K-HS progression that links decomposition of number with area models and algebraic expressions. Participants will use a variety of manipulatives and tools (including algebra tiles), and receive math lessons showcasing the connections.
