Welcome to the Eastern Oregon REN's 2026 K-8 Regional Math Challenge! You will find all of the challenge resources here. 

Where Do I Start?

• View the Challenge Kickoff Video for Challenge Instructions

• Review the Challenge Packet created by Steve Wyborney and choose challenge levels for your students to complete

What Do I Do After Completing the Challenge with My Students?

• Take at least one class action photo to submit while completing the Submission Form by Feb. 28

• By completing the submission form, you will be entered into a drawing to win a pair of Apple AirPods 

• Plus, your class will be entered into a drawing for a class party in a box

✅ Mathematical Principles Addressed Across Levels A–F

• Patterns & Sequences (predicting next colors, identifying growth patterns)

• Counting, Cardinality, & Structure (composing and decomposing 3D objects)

• Spatial Reasoning (visualizing rotations, holes, layers, and shapes not directly seen)

• Geometric Measurement (volume, dimensions, area in 2D/3D models)

• Algebraic Thinking (identifying rules for growing patterns, linear and non-linear growth)

• Modeling & Representation (using concrete manipulatives to represent abstract ideas)

• Problem Solving & Mathematical Reasoning (“How do you know?” prompts require justification)
