Dimensions Math 2A Tests

This test book supports the first semester of Dimensions Math's second-grade curriculum, which adapts Singapore's mastery-based mathematics approach for American classrooms and homeschools. The 150-page volume aligns closely with the 2A textbook content, assessing students' developing understanding of foundational arithmetic concepts through Singapore Math's characteristic emphasis on visual modeling and strategic problem-solving.

Each chapter offers two distinct assessments that build on each other. Test A evaluates whether students have grasped core concepts and can apply fundamental problem-solving strategies, while Test B advances to heuristic thinking and analytical applications—requiring students to select appropriate strategies and tackle multi-step problems independently. This dual structure reflects Singapore Math's progression from concrete understanding to abstract reasoning, allowing teachers to identify whether students need additional support with basic concepts before moving to complex applications.

Both test levels combine multiple-choice questions that check conceptual comprehension with free-response problems where students demonstrate their problem-solving process. An answer key in the back enables efficient grading and helps identify specific areas where students may need review or enrichment.
