Dimensions Math 1A Tests

This test book covers nine chapters of first-semester first-grade mathematics: Numbers to 10, Number Bonds, Addition, Subtraction, Numbers to 20, Addition to 20, Subtraction Within 20, Shapes, and Ordinal Numbers. Two continual assessments provide cumulative evaluation opportunities across multiple chapters. The 174 perforated pages allow easy removal for test administration, and an integrated answer key offers convenient reference for checking student work.

Each chapter includes differentiated Test A and Test B assessments. Test A evaluates mastery of core concepts and fundamental problem-solving skills—ensuring students understand basic number relationships and can perform standard operations. Test B applies those concepts through analytical thinking and problem-solving heuristics, challenging students to use mathematical reasoning in varied contexts. Both tests combine multiple-choice questions with free-response problems, allowing students to demonstrate both conceptual understanding and their problem-solving processes.

The assessments align closely with the Dimensions Math 1A Textbook, following the Singapore Math approach of building from concrete number understanding through operational fluency. This progression from basic number recognition to addition and subtraction within 20 reflects the foundational numeracy skills that establish first-grade mathematical competence.
