MATATAG Curriculum — Research Brief

Working reference for every artifact in this repository. Compiled August 2026. Sources listed at the bottom.

1. What MATATAG is

MATATAG is the Department of Education's revised K to 10 basic education curriculum, launched 10 August 2023 after a two-year review of the K to 12 program. It replaces the 2013 K to 12 curriculum for Kindergarten through Grade 10. (Senior High School follows a separate revision track.)

The acronym stands for the department's four-part agenda:

Letter	Agenda
MA	MAke the curriculum relevant to produce job-ready, active, and responsible citizens
TA	TAke steps to accelerate delivery of basic education services and facilities
TA	TAke good care of learners by promoting learner well-being, inclusiveness, and a positive learning environment
G	Give support for teachers to teach better

The core problem it addresses

The 2013 curriculum was congested. MATATAG cuts learning competencies by roughly 70% — from more than 11,000 down to about 3,600 — so that time is redirected into depth of mastery rather than coverage. The explicit priority is foundational literacy and numeracy, in response to the Philippines' learning-poverty results in international assessments.

Rollout

Phased, beginning SY 2024–2025 with Kindergarten, Grade 1, Grade 4, and Grade 7 — the entry grade of each key stage. Remaining grades followed in subsequent school years.

2. Structure

Key stages

Key Stage	Grades	Emphasis
Key Stage 1	Kindergarten–Grade 3	Foundational literacy, numeracy, and socio-emotional skills
Key Stage 2	Grades 4–6	Consolidation and extension; transition to disciplinary thinking
Key Stage 3	Grades 7–10	Disciplinary depth; preparation for Senior High School tracks

MATATAG introduced key stage standards and grade level standards so that expectations at the end of each stage and each year are stated explicitly — this was a named gap in the previous curriculum.

Learning areas by grade

Grades 1–2 were cut from seven learning areas to five. Grade 3 adds Science and splits language.

Grades	Learning areas
1–2	Language, Reading and Literacy, Mathematics, Makabansa, GMRC
3	Filipino, English, Mathematics, Science, Makabansa, GMRC
4–6	Filipino, English, Mathematics, Science, Araling Panlipunan, EPP, MAPEH, GMRC
7–10	Filipino, English, Mathematics, Science, Araling Panlipunan, TLE, MAPEH, Values Education

Mathematics is the only learning area present in all ten grades, which is why this repository uses it as the spine for the Grade 1–10 artifact set. See ARTIFACT-SPEC.md.

Time allotment

Standard allocation is 45 minutes per learning area per day, five days a week, with Homeroom Guidance at 45 minutes once a week. DepEd Order No. 12, s. 2024 subsequently granted schools flexibility in time allotment, so schools may adjust within limits.

Every lesson plan in this repository is therefore built to a 45-minute session.

3. How a MATATAG curriculum guide is organised

Each subject CG uses a consistent set of organisers. Using the Science CG's own wording:

Organiser	What it does
Content	Signals the key areas of focus for a quarter
Content Standards	Indicate the conceptual level expected for the quarter
Learning Competencies	Identify the specific aspects of content for learners to achieve
Performance Standards	Provide a level teachers use to judge learner achievement at the end of each quarter
Performance Tasks	Sample tasks where the learner applies knowledge, understanding, skills, processes, values, and attitudes

The curriculum guide divides the school year into four quarters. From SY 2026–2027 the school calendar runs in three terms instead — Term 1 June–September, Term 2 September–December, Term 3 January–April — under DepEd Order No. 009, s. 2026. The CG's quarters are unchanged as an organisation of content; they are simply redistributed across the three terms. This repository keeps CG quarter attribution on every competency for that reason.

Mathematics content domains

The MATATAG Mathematics curriculum organises all ten grades under three content domains:

Number and Algebra
Measurement and Geometry
Data and Probability

Content is arranged in a developmental sequence — a domain is revisited each year with increasing complexity, rather than appearing once and disappearing.

4. The MATATAG Lesson Exemplar format

DepEd publishes Lesson Exemplars — model lessons showing what a MATATAG-aligned lesson looks like in practice. They are models, not scripts. The structure:

I.   CURRICULUM CONTENT, STANDARDS, AND LESSON COMPETENCIES
     A. Content Standards
     B. Performance Standards
     C. Learning Competencies and Objectives
     D. Content
     E. Integration

II.  LEARNING RESOURCES

III. TEACHING AND LEARNING PROCEDURE
     A. Activating Prior Knowledge      (short review; connect to known)
     B. Establishing Lesson Purpose     (why this matters; unlock vocabulary)
     C. Developing and Deepening        (explicitation, worked examples,
        Understanding                    lesson activities per sub-topic)
     D. Making Generalizations          (learners' takeaways; reflection)

IV.  EVALUATING LEARNING: FORMATIVE ASSESSMENT AND TEACHER'S REFLECTION
     A. Evaluating Learning
     B. Teacher's Remarks
     C. Teacher's Reflection

Every lesson plan in this repository follows these headings exactly.

5. Design principles this repository commits to

Drawn from the MATATAG agenda and from the practical realities of Philippine classrooms:

Principle	How it shows up in the artifacts
Fewer competencies, deeper mastery	One lesson targets one or two competencies, not six.
Foundational skills first	Number sense and place value get full sessions, not a passing mention.
Contextualisation	Peso amounts, sari-sari stores, barangay populations, local place names, jeepney fares — not imported contexts.
Learner well-being	Group activities assign roles so no learner is a bystander; no public ranking of low scorers.
Teacher support	Every artifact ships with materials lists, timings, answer keys, and differentiation notes.
Low-resource by default	Offline activities need paper, chalk, and recycled materials. Digital artifacts are single HTML files with no CDN, no build step, no internet at run time.
One language per artifact	Each artifact set is written wholly in a single language — never mixed. Grades 4–10 Mathematics is in English, the medium of instruction for the subject from Grade 4. Key Stage 1 falls under MTB-MLE, so those sets belong wholly in Filipino or the regional mother tongue. See `ARTIFACT-SPEC.md` §4.

6. Curriculum verification — resolved

The official curriculum guide is now committed to this repository.

docs/research/source/MATATAG-Mathematics-CG-2023-Grades1-10.pdf — MATATAG K to 10 Curriculum of the K to 12 Program: Mathematics, Grades 1–10, Department of Education, August 2023. 73 pages.
MATATAG-Mathematics-CG-2023-Grades1-10.txt — plain-text extraction for searching.

Everything in the Grade 4 artifacts is now checked against it. The Mathematics artifacts no longer rely on search-result summaries for anything.

What the check found

The structural description in this brief — key stages, content domains, CG organisers, the Lesson Exemplar headings, time allotment, learning areas per grade — held up. The quarter-by-quarter content did not. Six material errors were corrected; they are itemised in the Grade 4 syllabus §9.

The single most useful correction: every Grade 4 quarter draws on more than one domain, and three of the four lead with Measurement and Geometry. The earlier drafts assumed Number and Algebra dominated Quarter 1 and sequenced the whole year from that assumption.

One correction to this brief itself

The CG defines Key Stage 1 as Kindergarten to Grade 3 (p. 66), not Grades 1–3 as originally stated in §2 above. That has been corrected.

Still unverified

⚠️ School year structure — adopted, unread. The artifacts now follow the three-term calendar of DepEd Order No. 009, s. 2026 — 8 June 2026 to 8 April 2027, 201 class days, each term an instructional block plus an end-of-term block. The order itself could not be downloaded; the structure comes from reporting.
⚠️ Assessment weights — adopted, unread. The artifacts now use DO No. 015, s. 2026 — Written Works 20%, Performance Tasks 50%, Examinations 30%, replacing the 40/40/20 of DO No. 8, s. 2015. Same caveat: reported, not read.
⚠️ Term boundaries and week numbers. Which CG quarter falls in which term, and which week within it, is this repository's proposal. DepEd's Budget of Work would settle it and has not been obtained.
Other learning areas. Only the Mathematics CG is committed here. Science, Language, Makabansa and the rest are still described from search summaries.
Week-level sequencing. The CG assigns content to quarters, not to weeks. Any week-by-week ordering is a school decision. (Third-party weekly breakdowns place the Grade 4 place value lesson at Week 7, matching this repository's independent placement.)

Both flagged items come from search reporting, not the DepEd Orders themselves — this environment cannot reach either document. They are recorded rather than acted on, for exactly the reason §6 documents. See source-catalogue.md for what to obtain.

One question closed

Key Stage 1 language. MATATAG removed Mother Tongue as a subject in Grades 1–3 but retained the mother tongue as the medium of instruction through Grade 3 for all learning areas except the Filipino and English subjects. Grades 1–3 Mathematics artifacts therefore belong wholly in the mother tongue, as ARTIFACT-SPEC.md §5 already specifies. DepEd recognises 19 MTB-MLE languages, so that is potentially many parallel sets; Filipino is the practical default.

Network access, for the record

Direct download remains blocked in this environment — re-tested with WebFetch, curl and headless Chromium on 17 Aug 2026. The PDF above was supplied directly rather than fetched. The details are kept below because they explain why the earlier drafts were built the way they were.
