Identify and distinguish 3D shapes (cubes, cones, cylinders, spheres) and find them in the real world.
A fun, interactive lesson where students become 'Number Detectives' to master counting to 100 through games and pattern recognition.
A playful introduction to adding two one-digit numbers using hungry monsters and their favorite snacks. Students move from counting objects to understanding addition sentences.
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 multi-sensory math and art lesson for 1st and 2nd graders to explore 2D shape attributes through tactile creation and observation. Students identify shapes by sides and vertices while building textured geometric masterpieces.
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 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.
