Dimensions Math 1B Home Instructor’s Printouts

The Dimensions Math 1B Home Instructor's Printouts provide the complete set of activity and lesson sheets for the second half of first grade in this Singapore Math-based curriculum. These sheets support the program's emphasis on concrete, pictorial understanding before abstract concepts—students work with visual models and hands-on activities that build number sense, addition and subtraction strategies, and early measurement concepts. Each printout coordinates directly with specific lessons in the Home Instructor's Guide 1B, where teaching notes indicate when to use particular sheets.

While these materials are available as free downloads, this pre-printed version arrives in a three-hole punched, unbound format that slots directly into a binder. The set includes multiple copies of practice sheets where repeated work helps reinforce skills, saving the time and expense of identifying which sheets need duplicate printing. For families managing multiple subjects or students, having these materials pre-organized eliminates one more task from the homeschool routine.

The activity sheets range from geometric shape sorting and number line work to mental math exercises and word problem scenarios. They're designed to be used alongside manipulatives and discussion, not as independent worksheets—the corresponding instructor's guide provides the teaching framework that brings these materials to life for first-grade learners.
