Grid Guard Subtraction

A comprehensive toolkit of premium third-grade writing and mathematics lessons tailored to core academic standards, featuring highly scaffolded and student-friendly designs.

A comprehensive fifth-grade lesson on additive volume. Students learn to decompose composite 3D figures into non-overlapping rectangular prisms, calculate individual volumes using formula V = l × w × h, and add them together to find total volume in real-world engineering and building scenarios.

A 1-page teacher reference showing full solutions, decomposition steps, formulas, and final values for all problems on both the Structure Splitters Practice Sheet and the Exit Ticket.

A comprehensive 4-lesson sequence focused on mastering 3-digit subtraction, starting from standard alignment without regrouping to complex borrowing across zeros and mixed multi-digit addition/subtraction review.

An introductory lesson designed to establish a growth mindset, collaboration norms, and problem-solving strategies on the very first day of 6th-grade math.

A 1-page quick exit ticket assessment for students to complete at the end of the lesson. Contains one multiple choice concept check and one multi-step additive volume calculation.

A 5-day conceptual unit themed around a local bakery where students use concrete area models (pies, cakes, and brownies) to master identifying and naming fractions, designed for students 3 grade levels below 6th grade.

A guided small-group math intervention for 4th graders focusing on rounding multi-digit numbers using a color-coded place value approach and a step-by-step decision-making guide.

A 2-page student worksheet containing structured practice problems. Students find the missing dimensions of combined prisms, slice the structures, and calculate the total additive volume. Includes student workspace and diagrams.

An engaging math lesson helping 4th-grade students master multi-digit place value and regrouping through base-10 block drawing blueprints.

A 5-slide instructional presentation that introduces fifth-grade students to composite solid figures, shows vertical and horizontal decomposition strategies, walks through an interactive example, and checks for understanding.

A highly modeled, garage-themed addition and subtraction lesson for third and fourth graders working on a third-grade level, focusing on 2-digit and 3-digit operations without regrouping.
