An introductory lesson on fractions for 3rd grade, focusing on equal parts, naming fractions, and visual representations using circles and rectangles. Students act as 'Factory Inspectors' to ensure all parts are equal and correctly labeled.

A cross-curricular lesson for 1st-3rd graders that combines basic rhythm notation with addition and subtraction. Students decode musical patterns to solve "math mysteries" and perform rhythms.

A hands-on lesson where students measure various 'specimens' to the nearest half-inch and organize their data into a line plot to identify patterns.

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.
