A 12-lesson Tier 2 intervention sequence for third-grade multiplication standards, focusing on equal groups, arrays, and unknown factors using IM-aligned strategies and All Learners Network concepts.

A 3-day math sequence for 3rd graders focused on multiplication comparisons and identifying patterns in tables using a fun Toy Factory theme.

This sequence utilizes base-ten blocks and area models to scaffold multi-digit multiplication and division, providing a visual and tactile framework for students who struggle with standard algorithms. By connecting physical area models to expanded form and eventually the standard algorithm, students build a conceptual foundation that supports future algebraic learning.

A specialized math sequence for 3rd Grade students focusing on visual strategies for multiplication and division. This unit uses arrays, equal groups, and area models to build conceptual understanding for students who benefit from spatial and visual support.

This 3rd-grade sequence introduces the Concrete-Representational-Abstract (CRA) framework using bar models (tape diagrams) to visualize additive relationships. Students transition from physical linking cubes to drawn rectangles, mastering part-part-whole and comparison models to decode and solve word problems.

A 5-lesson unit where 3rd-grade students explore the hidden rules and patterns within the multiplication table, arithmetic operations, and algebraic functions. Students move from observation to prediction and generalization.

A 5-lesson unit for 3rd graders focused on using open number lines to visualize, place, and compare numbers. Students act as 'Number Navigators' to master proportional reasoning and magnitude.

A 3rd-grade math sequence where students apply the four operations to plan a school 'Field Day'. They will solve two-step word problems, use variables for unknown quantities, manage a budget, and justify their mathematical reasoning through a final event plan.

A 3rd-grade sequence exploring algebraic thinking through arithmetic patterns, properties of operations (associative, distributive), and function machines. Students move from observing patterns in addition and multiplication tables to applying properties as strategic calculation tools.

This inquiry-based sequence focuses on algebraic thinking by exploring numerical patterns and functional relationships. Students progress from simple repeating and growing patterns to identifying explicit rules and using them to predict future terms.
