A 4th-grade math lesson on identifying and generating equivalent fractions using visual models like fraction strips and bars, and applying multiplication and division rules.

A focused practice session on basic multiplication and division facts up to 12x12. Students will solve five multiplication and five division equations to build fluency.

A lesson focused on mastering addition and subtraction of fractions with unlike denominators using the cross-multiplication (butterfly) method. Students use structured graphic organizers to visualize each step of the process.

In this hands-on geometry exploration, students venture outside to measure the angles of shadows cast by playground equipment and trees at different times of day. They apply their protractor skills to record data and analyze how the sun's position changes angle measurements.

Fourth graders explore line symmetry through Indiana's local flora and fauna, identifying mathematical patterns in nature and creating original geometric art.

A foundational lesson designed for SIFE students to understand fractions greater than one using visual models and fraction strips. Focuses on bridging concrete models to number lines with minimal text reliance.

A foundational lesson on equivalent fractions using area models and number lines, styled as architectural blueprints to emphasize precision and measurement.

Analyzing and creating line plots to represent measurement data.

Using fraction equivalence to measure and record lengths accurately.

Expanding measurement skills to fourths of an inch and practicing with mixed numbers.

Introduction to measuring length in halves of an inch and understanding mixed numbers.

A project-based lesson where students design a sustainable community center, applying area and perimeter calculations to complex polygonal floor plans with fractional dimensions.

A hands-on math simulation where 4th-grade students use multi-digit multiplication and division to launch and manage a food truck business. Students calculate bulk ingredient costs, set menu prices, and analyze profit margins to prepare for the ultimate rally.

A quest-themed lesson on 3-digit long division with remainders, featuring a 5-page practice mission.

A focused lesson on mastering long division (3-digit by 1-digit) with remainders, using grid-aligned blueprints to help students organize their calculations and maintain place value accuracy.

A collection of multi-step word problem challenges focused on mastering the four operations through a detective-themed investigation. Students apply critical thinking to identify operations and solve complex scenarios.

A precision-focused drafting-themed review of 4th grade Measurement and Data (MD) standards. Covers units and conversions (MD.1), measurement word problems (MD.2), area and perimeter (MD.3), line plots (MD.4), and angle measurement and addition (MD.6-7). Division has been removed from the curriculum.

A comprehensive slide deck covering measurement in inches (halves and fourths) and interpreting data on line plots, provided in both English and Japanese.

Students act as urban architects to design a town using quadrilaterals on a grid, calculating perimeter and area for their structures.

A comprehensive unit on finding the perimeter of various polygons, including unknown side lengths and real-world word problems, themed around architectural blueprints.
