A 45-minute investigation into the interior angles of quadrilaterals, where students discover the 360-degree rule by dividing shapes into triangles and solve for missing 'clue' angles.

This lesson focuses on mastering the order of operations (PEMDAS) and evaluating numerical expressions with exponents. Students will practice applying rules systematically to solve multi-step problems without negative numbers.

A comprehensive unit assessment on exponents and the order of operations, designed for a 60-minute testing block with no negative numbers. Includes practice on identifying steps and evaluating complex expressions.

A comprehensive assessment and review lesson covering the Order of Operations (PEMDAS) and exponents, specifically designed for middle schoolers without negative numbers.

A comprehensive lesson on multiplication facts 1-12 using arrays and skip counting strategies, styled as architectural blueprints.

A comprehensive lesson focused on identifying, naming, and comparing fractions using visual models, number lines, and real-world applications. Students move from basic identification to complex comparisons of fractional parts.

A comprehensive introduction to simplifying fractions using a 'Shrink-O-Matic' lab theme. Students learn to identify common factors and divide to reach the simplest form through differentiated practice and visual models.

A lesson focused on decoding word problems using addition, subtraction, multiplication, and division facts through a detective-themed investigation. Students learn to identify key operations and solve tiered challenges of increasing complexity.

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 comprehensive assessment on the Order of Operations (PEMDAS) and basic exponents, designed for a 30-minute testing window with mixed question types.

A comprehensive lesson on the order of operations (PEMDAS) and basic exponent rules, featuring a visual organizer, practice problems, and a summative assessment.

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.
