A 3rd-grade introduction to perimeter, focusing on calculating the distance around rectangles and squares using addition and properties of shapes. Students explore real-world applications like fencing a garden to understand why perimeter matters.

A hands-on geometry lesson where students explore the properties of 2D polygons, including sides, angles, and defining characteristics through classification and sorting.

A lesson focused on mastering place value for numbers up to 10,000, covering standard, word, and expanded forms with a focus on deep conceptual understanding and multi-step problem solving.

A math lesson focused on double-digit by single-digit addition, featuring a mix of regrouping and non-regrouping problems with a fun robot theme.

Advanced elapsed time practice focusing on five-minute intervals, providing the highest level of challenge in this unit.

Materials for mastering elapsed time in 15, 30, and 45-minute increments using scenarios and analog clocks.

A project-based math lesson where 3rd-grade students apply elapsed time concepts to plan a detailed day at a major theme park. Students select a park, schedule their arrival and departure, and calculate durations for meals and special events.

A focused lesson on mastering multi-digit subtraction without regrouping, featuring a graph-paper styled assessment.

A lesson on 4-digit subtraction without regrouping, featuring a space-themed instructional slide deck and a grid-supported practice worksheet. Students will learn to subtract each column independently while maintaining place value alignment.

A Grade 3 math lesson where students act as detectives to identify 2D shapes, polygons, quadrilaterals, right angles, parallel lines, and lines of symmetry in the classroom.

A foundational geometry lesson where students identify, classify, and compare different types of quadrilaterals using visual scaffolds.

A geometry lesson where students become 'Shape Architects', identifying quadrilaterals by their unique attributes like angles and side lengths. Students use color-coded visual cues and checklists to classify squares, rectangles, rhombuses, parallelograms, and trapezoids.

A comprehensive review of 3rd-grade geometry concepts including polygons, quadrilaterals, angles, and vertices, styled as a field scout's handbook.

A comprehensive review session covering all 3rd-grade math domains to prepare students for the MCAS. This lesson provides visual aids like base-ten blocks, number lines, and arrays to support problem-solving strategies.

A lesson focused on the specific technique of regrouping across multiple place values containing zeros. Students use a step-by-step checklist to navigate the vault-cracking process of borrowing from distant neighbors.

A lesson focused on multi-step addition and subtraction word problems with regrouping, designed for students transitioning to 4th grade. It includes visual supports, structured problem-solving steps, and data tracking for IEP goal monitoring.

A lesson focused on solving complex two-step word problems using all four mathematical operations.

A lesson focused on mastering 4-digit subtraction with regrouping, featuring structured borrowing boxes to guide students through the process.

A space-themed lesson focusing on multi-digit subtraction with regrouping. Students will practice borrowing across tens, hundreds, and thousands places using clear visual organizers.

A lesson focused on comparing fractions with different denominators using number lines as a visual model. Students will learn to partition number lines and identify which fraction represents a greater distance from zero.

A foundation-level lesson on the order of operations (MDAS) designed for IEP students, focusing on the hierarchy of multiplication, division, addition, and subtraction without brackets or exponents.

A comprehensive May preparation pack for Grade 3 students, focusing on Math MCAS readiness and ELA research skills using the Magic Tree House nonfiction companion on the American Revolution.
