A comprehensive lesson on adding and subtracting fractions with like and unlike denominators, focusing on the 'Pizza Chef' method for finding common denominators and the 'Slicing it Down' method for simplifying results.

A cumulative review and performance assessment where students solve 5 oral or pictorial problems to 30, demonstrating mastery of the unit's goals.

Combining skills to determine the correct operation (+/-) for oral and pictorial problems, writing the number sentence, and solving using a number line.

Focusing on subtraction within 30 using number lines and a monster truck theme. Students will practice 'reversing' or 'crushing' numbers by moving backward on the number line.

Focusing on addition within 30 using number lines and a Lego building theme. Students will practice 'building up' their totals by hopping forward on the number line.

A review of math vocabulary for addition and subtraction using a Golden State Warriors theme. Students will learn to identify keywords in oral problems to determine whether to add or subtract.

Synthesizes skills through word problem solving and a final fluency check to measure progress.

Explores the Commutative and Associative properties to simplify complex multiplication and build mental math strategies.

Transitions students from visual area models to the partial products strategy for more efficient calculation.

Introduces the area model for 2-digit by 1-digit multiplication, connecting place value to the distributive property.

Focuses on the conceptual foundation of multiplication as equal groups and arrays using manipulatives and visual modeling.

An introductory lesson on creating and interpreting line plots using fractional measurements (halves, fourths, and eighths). Students become 'Data Detectives' to measure 'clues' and organize their findings on a number line.

A comprehensive lesson for 4th grade students to master plotting and identifying fractions on a number line with common denominators using a railway-themed approach.

A project-based lesson where students apply geometry skills to design and build a 3D miniature city, focusing on polyhedra, volume, and spatial reasoning.

A 60-minute introductory lesson for 4th graders on creating and interpreting line plots using mixed numbers, specifically focusing on measurements to the nearest 1/8 inch.

A lesson focused on collecting plant measurement data and plotting mixed numbers on a number line to visualize growth patterns.

A comprehensive lesson on mastering analog clocks and calculating elapsed time, designed for middle school students with a focus on logical deduction and practical application.

A 30-minute introductory lesson focusing on representing fractions and decimals using 10x10 and 10x1 grids. Students will visualize parts of a whole to build conceptual understanding.

The cumulative review and assessment where students solve mixed-theme problems independently to demonstrate 70% accuracy.

Develops flexibility and number sense by teaching efficient jumps on the number line (jumping by 2s, 5s, or 10s) within the context of all three themes.

Integrates Golden State Warriors stats and basketball gameplay to practice writing number sentences and solving subtraction up to 30.

Uses high-octane monster truck scenarios to help students identify keywords for operations (+/-) and practice solving on dirt-track number lines.

Focuses on the physical representation of addition and subtraction using LEGO bricks and building the foundation for number line jumping up to 20.

A high-tech exploration of Soroban abacus mechanics, framed as calibrating a powerful logic engine through complement techniques and precise multiplication chains.
