By January 2026, given anchor charts and teacher modeling, Zoee will be able to write and solve simple equations for an unknown angle in a figure with 90% accuracy in 4 out of 5 trials. as measured by classroom assessments.

This learning resource is focused on solving for unknown angles, with an emphasis on understanding key angle relationships such as complementary, supplementary, vertical, and adjacent angles. The resource outlines learning goals, reviews fundamental concepts, and provides worked examples to guide students through solving equations that find unknown angles in various geometric contexts, particularly involving triangles and parallel lines with transversals. Students will also have opportunities for guided and independent practice, with checklists and reflection sections to promote self-assessment and deeper understanding.
