Instructional slides for the Alignment Architects lesson. Includes a messy warm-up problem, the embedded Matholia subtraction video, discussion questions based on the video timestamps, and clear activity instructions.
Precision Problems Worksheet
A student worksheet containing horizontal subtraction problems that must be transferred to graph paper. Includes a variety of digit lengths (4-digit minus 3-digit, 4-digit minus 4-digit) to challenge students' vertical alignment skills.
Architect Grid Paper Document
Custom large-grid graph paper (40px squares) designed for vertical alignment practice. Features a blueprint aesthetic to engage students in "precision math" and includes headers for name and date.
Shift Detector Exit Ticket
An exit ticket where students must identify an alignment error in a subtraction problem (4-digit minus 3-digit where the smaller number is incorrectly shifted). Students explain the error and rewrite it correctly on a grid.
