Assessing Math Concepts - Combination Trains

Assessing Math Concepts: Combination Trains helps teachers understand how children think about number combinations and early addition. This resource focuses on how students compose and decompose numbers and how flexibly they work with combinations that form a given total.

Combination Trains provides clear assessment tasks that reveal student thinking about part whole relationships. Teachers gain guidance, observation tips, and reproducible black line masters that support classroom instruction, small group intervention, and progress monitoring.

This resource strengthens foundational understanding needed for addition and subtraction fluency and is ideal for early elementary classrooms and intervention programs.
