Illustrative Mathematics® v.360: Problem-Based Inquiry Curriculum

Illustrative Mathematics® v.360 is an innovative problem-based K–8 math curriculum that emphasizes inquiry-driven learning and mathematical practices. The curriculum is designed around a three-phase lesson structure (readiness, engagement, mastery) and received high ratings from EdReports across all evaluation gateways.

Best for

Teachers and schools seeking a problem-based, inquiry-driven approach to mathematics instruction, particularly those with strong teacher preparation and students who have solid foundational skills

Evaluation Criteria

2 strengths · 3 concerns · 1 neutral · 3 insufficient evidence

Word ProblemsStrength

The curriculum strongly emphasizes problem-solving and application through its problem-based design, likely providing extensive word problem practice.

The curriculum is described as 'problem-based' and designed to 'energize math classrooms and equip students with critical skills,' suggesting strong emphasis on problem-solving contexts

Teacher TrainingStrength

The curriculum received high ratings for usability from EdReports, suggesting adequate teacher support materials are included.

EdReports rated the curriculum 'Meets Expectations' for Gateway 3 Usability, which includes 'teacher supports' as a key component

Direct InstructionConcern

The curriculum emphasizes inquiry-based learning over direct instruction, which may not align with research supporting explicit teaching for foundational skills.

The curriculum is explicitly described as 'problem-based' and 'inquiry-driven,' suggesting less emphasis on direct, explicit instruction approaches

Sequencing ApproachConcern

The curriculum uses a problem-based sequencing approach that may not adequately scaffold foundational skills. There are concerns about assuming prerequisite knowledge without sufficient review.

Rubinstein argues the curriculum 'assumes students have prior foundational knowledge' and 'fails to scaffold basic algebraic problem-solving adequately,' suggesting sequencing issues particularly for students without prior IM instruction

Conceptual Procedural BalanceConcern

The curriculum emphasizes conceptual understanding through problem-based learning but may lack adequate procedural fluency development. Critics note concerns about insufficient explicit practice with foundational skills like solving linear equations.

EdReports rated it 'Meets Expectations' for rigor balance, but Rubinstein's critique highlights gaps in procedural skill mastery, noting the curriculum 'assumes students have prior foundational knowledge' and lacks 'explicit mastery opportunities for essential skills'

Assessment DiagnosticNeutral

The curriculum received positive ratings for assessment from EdReports, though specific diagnostic features are not detailed in the reviews.

EdReports' Gateway 3 rating of 'Meets Expectations' includes assessment as a component, suggesting adequate assessment tools are present

Worked ExamplesInsufficient Evidence

Evidence about worked examples and step-by-step modeling is insufficient in the available reviews. The problem-based approach may emphasize discovery over explicit modeling.

The reviews focus on the inquiry-based methodology but do not specifically address the presence or quality of worked examples

Retrieval PracticeInsufficient Evidence

Information about systematic retrieval practice and spaced review is not evident in the available reviews.

Reviews do not mention specific features for retrieval practice, cumulative review, or spaced repetition of skills

Visual RepresentationsInsufficient Evidence

The curriculum appears to incorporate visual representations as part of its problem-based approach, though specific details are limited in the reviews.

The curriculum is described as 'problem-based' and 'innovative,' suggesting use of varied representations, though reviews don't detail specific visual models
