Assessing Math Concepts - More/Less Trains

Assessing Math Concepts: More/Less Trains is part of a nine part series designed to help teachers understand how young learners develop essential early math concepts. This resource focuses specifically on a child's ability to compare quantities, recognize differences between groups, and determine how many more or how many less one number is than another.

The assessment tasks in More/Less Trains give teachers reliable tools for observing how students think about quantity and comparison in a variety of settings. Background information, clear guidance for administering assessments, and support for organizing data help teachers use the results to shape instruction with confidence. Black line masters are included and can be reproduced for classroom and small group activities.

More/Less Trains helps teachers identify where each learner is on the developmental path toward strong number comparison skills, making it an ideal resource for classroom instruction, intervention, and ongoing progress monitoring.
