An inquiry-based exploration of triangular and square numbers where students discover formulas through visual manipulation and structural analysis.
A comprehensive review of exponential growth, decay, and compound interest through real-world scenarios. Students practice applying discrete and continuous formulas to predict future values.
A lesson focused on introducing and practicing telling time to the half-hour, connecting analog and digital representations.
A collection of tools for tracking student progress in mastering number decompositions for 6 and 7.
A lesson introducing the distributive property through the metaphor of a delivery service, featuring guided and independent practice.
A comprehensive lesson on classifying quadrilaterals based on their properties, focusing on the hierarchy and inclusive definitions required for 5th-grade geometry.
A lesson focused on understanding and applying z-scores to compare values from different normal distributions and interpret real-world statistical data.
Students will model the exponential growth of a pepper population, starting from one pepper and doubling every season, to understand the power of geometric growth.
A comprehensive set of small group activities where students calculate unknown angles and determine the area of various figures using tiling and equations. The lesson uses a 'Blueprint Builders' theme to engage students in real-world mathematical applications.
A 45-minute lesson exploring inverse variation through the lens of travel speed and Boyle's Law, focusing on formulating and solving equations for real-world scenarios.
