This String Art Geo Design Challenge project directly supports NGSS Standards MS.ETS.1.1–1.4: Students will apply mathematical reasoning and data analysis to engineer, test, and improve design solutions by identifying problems, evaluating and comparing solutions with quantifiable data, and using models and iterations to refine their designs. The purpose of this 45 minute, 5E investigation is to  investigate geometric patterns, angles, symmetry, and spatial reasoning by creating a string art geometric design while applying STEAM design principles. Students will use string and geometric shapes to create colorful mathematical art designs while exploring geometric relationships and design problem-solving.This package includes power point resources, a lesson plan, instructor activity guide, students activity guide, response worksheet, answer key, and digital response worksheet. Just print, prep, and it’s ready to go.
