About This Curriculum

<cite index="11-1">Japan Math is an elementary mathematics curriculum developed with the knowledge and wisdom that Japanese educators have accumulated over decades.</cite> <cite index="18-7">Primary Math International uses a 4-step approach to learning - Try, Understand, Apply, Master - which aims to foster a deep understanding of math concepts.</cite>

What makes it unique: <cite index="2-1,2-4">The curriculum encourages students to find joy in their lessons and removes emphasis on quickly solving problems and fear of unsuccessful attempts from the learning process.</cite>

Japan Math: Elementary Inquiry-Based Curriculum with Implementation Challenges

Japan Math is a K-2 mathematics curriculum that incorporates Japanese educational approaches and uses a 4-step learning framework (Try, Understand, Apply, Master). The curriculum emphasizes inquiry-based learning and aims to foster deep conceptual understanding of mathematical concepts.

Best for

Educators interested in Japanese mathematical approaches and inquiry-based learning, though implementation may require significant supplemental materials and training

Evaluation Criteria

3 concerns · 6 insufficient evidence

Worked ExamplesConcern

The inquiry-based pedagogy may not emphasize worked examples as heavily as direct instruction approaches.

Curriculum is described as inquiry-based, which typically emphasizes student discovery over teacher modeling of worked examples

Direct InstructionConcern

The inquiry-based approach appears to de-emphasize direct, explicit instruction in favor of student discovery.

Curriculum is explicitly described as using inquiry-based pedagogy rather than direct instruction methods

Conceptual Procedural BalanceConcern

The curriculum's 4-step approach suggests attention to both understanding and mastery phases, but alignment concerns raise questions about balance.

The Try-Understand-Apply-Master framework indicates conceptual development followed by application, but EdReports found the curriculum does not meet expectations for alignment to grade-level standards

Word ProblemsInsufficient Evidence

The 'Apply' step suggests attention to application, but systematic word problem instruction approach is unclear.

The 4-step framework includes an 'Apply' phase, indicating some focus on application of concepts, but no details about word problem schemas or systematic instruction

Teacher TrainingInsufficient Evidence

Insufficient evidence to determine the extent of teacher support and professional development materials.

No information provided about teacher guides, training materials, or professional development support

Retrieval PracticeInsufficient Evidence

The 'Master' phase of the 4-step approach may include practice, but specific retrieval and spaced review components are unclear.

The framework includes a 'Master' step, suggesting some form of practice, but no details about systematic retrieval practice or cumulative review

Sequencing ApproachInsufficient Evidence

Insufficient evidence to determine whether the curriculum uses effective mastery-based or spiral sequencing.

No specific information provided about how mathematical topics are sequenced or revisited across grade levels

Assessment DiagnosticInsufficient Evidence

Insufficient evidence to assess the curriculum's diagnostic assessment capabilities.

No information provided about formative assessments, diagnostic tools, or progress monitoring features

Visual RepresentationsInsufficient Evidence

Insufficient evidence to assess the curriculum's use of visual models and manipulatives.

No specific information provided about visual representations or concrete-representational-abstract progression
