Assessing Math Concepts - Hiding Assessment

Assessing Math Concepts: Hiding Assessment helps teachers understand how children think about number combinations and part whole relationships. This resource focuses on a student's ability to recognize hidden parts of a number and to reason about quantities that are partially concealed. These skills are essential for developing strong number sense and mental addition strategies.

The assessment tasks in Hiding Assessment give teachers clear opportunities to observe how students explain what they see, what they know, and how they determine the missing part of a number. Teachers receive background information, guidance for administering assessments, observation tips, and reproducible black line masters for classroom and small group use.

Hiding Assessment supports early numeracy development by revealing how flexibly children work with numbers and how well they understand the structure of quantities. It is ideal for classroom instruction, intervention, and progress monitoring.
