A culminating challenge where students use all properties to solve a complex multi-step problem.

Building fact families to illustrate the inverse relationship between multiplication and division.

Connecting division to multiplication by finding missing factors in array models.

Using the associative property to find more efficient paths to solving multiplication problems.

Modeling three-factor multiplication using 3D block structures or stacked arrays.

Introduction to the associative property by exploring how grouping three factors differently results in the same product.

Connecting decomposing arrays to the formal notation of the distributive property using parentheses.

Using area models to visually break apart complex arrays into two smaller, easier-to-manage arrays.

Introduction to the distributive property by decomposing larger factors into 5 and 2.

Students apply the commutative property to solve context-based problems and match expressions to visual models.

Students reinforce the commutative property by translating equal groups into arrays and vice versa.

Students explore the commutative property of multiplication using arrays and physical tiles to understand that order does not change the total.

Students learn the incrementing strategy to add numbers up to 100 by breaking the second addend into tens and ones and 'jumping' along a number line. This visual approach builds mental math fluency and place value understanding.

A lesson on addition within 100 using the incrementing algorithm. Students learn to break down the smaller part into its place values and add them step-by-step to the larger part using a "mountain jumping" visual theme.

A cumulative review and assessment day. Students complete a 'Final Inspection' quiz to demonstrate mastery and participate in a collaborative 'Lab Graduation' challenge.

Students apply their subtraction skills to solve complex, multi-step word problems. The lesson focuses on identifying keywords and creating 'evidence logs' to organize mathematical steps.

Addresses the specific challenge of regrouping when the minuend contains one or more zeros. Students learn the 'Middle Man' strategy to pass value from the hundreds place through the tens to the ones.

Advances to problems requiring students to regroup twice (from both the hundreds and tens places). Students practice identifying when multiple swaps are necessary to complete a calculation.

Focuses on the fundamentals of 3-digit subtraction with a single instance of regrouping (either tens or ones). Students learn the conceptual "Great Trade" strategy and apply it to basic lab blueprint problems.

A comprehensive 3rd-grade math assessment covering whole number operations, including addition, subtraction, multiplication, and division through word problems and numerical expressions.

A comprehensive 3rd-grade assessment covering multi-digit addition and subtraction with regrouping, along with fundamental multiplication and division word problems.

A comprehensive 3rd-grade math assessment designed as a secret agent mission, covering multi-digit addition and subtraction, multiplication, division, and complex word problems.

A comprehensive 3rd-grade math assessment and review focusing on computation skills and multi-step word problems within 1,000 and basic multiplication/division.

A diagnostic lesson designed to evaluate 3rd-grade mathematical proficiency through two levels of assessment: a quick 10-question sprint and a comprehensive 25-question deep dive.

Tier 2 intervention materials for students needing extra support with mixed numbers and improper fractions. This lesson provides visual scaffolds, simplified language for struggling readers, and hands-on practice activities to reinforce foundational fraction concepts.

Students explore the foundational concepts of fractions, focusing on equal parts, numerators, and denominators through the lens of architectural blueprints and building blocks.

A comprehensive geometry lesson that explores 2D and 3D shapes and angles through a space exploration lens, designed for 3rd and 5th-grade students. Students will navigate the 'Geometry Galaxy' to identify, classify, and build geometric figures using spatial reasoning.

A comprehensive geometry lesson exploring 2D and 3D shapes, properties, and angles through a space-themed mission. Students engage in classification, modeling, and spatial reasoning to master geometric concepts.

A comprehensive lesson on mastering the US standard subtraction algorithm up to the thousands place using structured grids and visual guides.

Covers all four operations in two-step problems related to buying souvenirs and managing a final vacation budget.

Introduces multiplication into two-step word problems focused on island activities like surfing and snorkeling.
