A lesson focused on solving two-step word problems using the four operations, representing unknowns with letters, and checking for reasonableness.

A 15-25 minute exploration into how ancient navigators used fixed points (the North Star) and the repeating patterns of the universe (microcosms, macrocosms, and symmetry) to navigate without modern technology.

A 15-30 minute exploration of how ancient Phoenicians used the macrocosm of the stars to navigate the microcosm of their ships, featuring the root words micro/macro/cosmos and the mathematics of rotational symmetry.

Students transition from scouts to architects, applying their research to design a complex structure blueprint. They will calculate additive angles, classify polygons within their design, and present their final architectural plan.

Students become Geometry Scouts, researching and documenting real-world examples of lines, angles, and two-dimensional figures. They will use protractors to measure angles in their environment and identify geometric properties in architecture and nature.

A high-energy, 45-minute comprehensive math review covering place value, fractions, and multi-step word problems for grades 3-5, designed as a 'Math Marathon'.

A high-energy, medical-themed 50-minute review of proportional relationships, equations, and geometry for middle school students, featuring error analysis and state-test style practice.

A comprehensive set of bulletin board resources and student activities focused on understanding fractions and decimals through the hundredths place, aligned with 4th Grade Texas TEKS.

A middle school math lesson exploring proportional reasoning through real-world scaling, mapping, and budgeting scenarios. Students use visual models and multiple pathways to solve authentic problems.

A conceptual introduction to fractions using a bakery theme. Students explore area, set, and linear models through a collaborative 'Great Bakery Mix-up' task designed with UDL principles to ensure all learners can access deep mathematical concepts.
