A high-energy, spy-themed lesson where students master the order of operations through matching challenges and a mystery-solving color activity.

A lesson focused on mental math strategies for double-digit addition, specifically exploring how to maintain a sum while changing addends (conservation) and how to efficiently add increments of tens and ones.

Compose new shapes from smaller shapes and decompose larger shapes into smaller ones.

Identify and distinguish 3D shapes (cubes, cones, cylinders, spheres) and find them in the real world.

Identify and describe 2D shapes (circles, triangles, squares, rectangles) by their sides and vertices.

A 3rd-grade math expedition where students solve 2-step addition and subtraction word problems using a 5-step safari protocol: Jungle Scan, Expedition Goal, Scout the Trail, Mapping the Model, and Final Report.

Final mastery check of AZ 3.G.A.2 skills: partitioning shapes, identifying unit fractions, and explaining the relationship between parts and the whole area.

Students explore how the same shape can be partitioned into equal areas in multiple ways, reinforcing that fractional parts must have equal area but not necessarily identical shapes.

Students partition circles, rectangles, and squares into 2, 3, 4, 6, and 8 equal parts with precision, meeting the partitioning requirements of the AZ standards.

Students express the area of one part as a unit fraction (1/b) of the whole, connecting partitioning to numerical notation as required by AZ 3.G.A.2.

Students define equal shares and identify them in circles and quadrilaterals, establishing the foundation for AZ 3.G.A.2 by distinguishing area from shape.

A final review and assessment of all skills learned throughout the Fraction Factory unit.

Exploring different ways to partition the same shape into equal areas, reinforcing that shapes can look different but have the same fractional area.

Practicing partitioning circles, rectangles, and squares into specific numbers of equal parts (2, 3, 4, 6, 8).

Focuses on naming the partitioned parts as unit fractions (1/b) and understanding that the size of the part depends on the total number of parts.

An introduction to identifying and creating equal parts in various shapes, distinguishing between fair and unfair shares in the context of factory production.

A final assessment day where students demonstrate mastery of area concepts including tiling, multiplication, and decomposing rectilinear shapes in the context of a community garden project.

Students apply their knowledge of area to more complex gardening scenarios, including decomposing rectilinear shapes and comparing garden sizes.

In this lesson, students learn to relate tiling to multiplication to find the area of rectangular garden plots. They will count square units and then transition to using side lengths.

A comprehensive lesson on basic budgeting, financial vocabulary, and mathematical foundations including fractions and simple algebra, designed for special education students.

A high-energy, St. Patrick's Day themed math game where 4th graders solve multi-step word problems to earn gold coins and reach the end of the rainbow.
