TL;DR: DepEd's current official Mathematics Curriculum Guide is the MATATAG version for Grades 1-10, published August 2023 and available directly from deped.gov.ph as a single consolidated file. It organizes competencies under three content domains, Number and Algebra, Measurement and Geometry, and Data and Probability, and aims to build five strands of mathematical proficiency drawn from NRC research. With MATATAG's Phase 3 rollout covering Grades 6, 9, and 10 starting SY 2026-2027, this version now governs Math instruction across every grade from 1 through 10.
This post is part of our DepEd curriculum guides hub, which indexes the official file for every subject. Mathematics is the one core subject where DepEd publishes a single curriculum guide spanning all ten grades, rather than splitting the file by grade range as it does for English and Science. This guide covers how the Math CG is structured, what its three content domains and five proficiency strands mean in practice, and where to get the verified official file.
What Is the Current DepEd Mathematics Curriculum Guide?
The current official Math CG is the MATATAG version covering Grades 1-10, dated August 2023 and titled "MATATAG Curriculum: Mathematics (Grades 1-10)" on deped.gov.ph. It replaced the 2016 K to 12 Math CG under the same MATATAG curriculum overhaul that revised every other K-10 subject.
MATATAG's rollout reached Math in three phases: Grades 1, 4, and 7 in SY 2024-2025 (Phase 1), Grades 2, 3, 5, and 8 in SY 2025-2026 (Phase 2), and Grades 6, 9, and 10 in SY 2026-2027 (Phase 3). Because Math is taught from Grade 1 onward, its MATATAG transition is now complete across every grade level the subject covers.
| File (as published by DepEd) | Grade Coverage | Notes |
|---|---|---|
| MATATAG Curriculum: Mathematics (Grades 1-10) | Grades 1-10 | Current, complete version, single file |
| MATATAG Mathematics CG (Grades 1, 4, and 7 only) | Grades 1, 4, 7 | Superseded Phase 1 partial file |
Disclaimer: DepEd periodically renames or relocates files on deped.gov.ph. If a link stops working, search "MATATAG Mathematics curriculum guide" directly on the DepEd website rather than relying on a third-party mirror, which may be hosting an outdated version.
How Is the Math CG Organized?
DepEd's Math CG groups every competency, from Grade 1 through Grade 10, under three content domains:
| Content Domain | What It Covers |
|---|---|
| Number and Algebra | Whole numbers, fractions, decimals, ratio and proportion, patterns, equations, functions, sequences |
| Measurement and Geometry | Shapes, angles, area, perimeter, volume, symmetry, transformations, trigonometry basics |
| Data and Probability | Data presentation and interpretation, graphs, statistical measures, probability of events |
These three domains replace the five strands used in the 2016 curriculum (Numbers and Number Sense, Measurement, Geometry, Patterns and Algebra, and Statistics and Probability), effectively merging Geometry with Measurement and folding Patterns and Algebra into Number and Algebra. The topics inside each domain grow steadily more complex by grade: Number and Algebra starts with whole numbers up to 100 in Grade 1 and reaches quadratic equations and compound interest by Grade 10; Measurement and Geometry moves from simple 2D shapes to the Pythagorean Theorem, triangle congruence, and circle theorems; Data and Probability progresses from simple pictographs to box-and-whisker plots and independent/dependent events.
What Are the Five Strands of Mathematical Proficiency?
Separate from the three content domains, the CG cites five intertwining strands of mathematical proficiency, drawn from the U.S. National Research Council's 2001 framework, that describe the qualities the curriculum aims to build in every learner regardless of grade or domain:
- Conceptual Understanding — comprehension of mathematical concepts, operations, and relations
- Procedural Fluency — skill in carrying out procedures flexibly, accurately, and efficiently
- Strategic Competence — the ability to formulate, represent, and solve mathematical problems
- Adaptive Reasoning — the capacity for logical thought, reflection, and justification
- Productive Disposition — a habitual inclination to see mathematics as sensible, useful, and worthwhile
The CG frames these strands as running through every content domain and key stage rather than being taught as a separate unit, which is why performance standards for each grade typically describe learners "applying" knowledge "to the processes within Mathematics of critical thinking, problem solving, communicating, reasoning, and making connections between topic areas."
How Are Math Key Stages Structured?
| Key Stage | Grades | Focus |
|---|---|---|
| Key Stage 1 | 1-3 | Foundational competencies across all three content domains |
| Key Stage 2 | 4-6 | Extension to more complex operations, ratio, percentage, decimals, and multi-step problems |
| Key Stage 3 | 7-10 | Algebra, functions, geometric proofs, trigonometry basics, and statistical measures |
By the end of Grade 3 (Key Stage 1), learners are expected to work with whole numbers up to 10,000, basic fractions, simple shapes, and pictograph data. By the end of Grade 6 (Key Stage 2), learners are expected to handle the four operations with fractions and decimals, ratio and proportion, percentages, volume of solids, and theoretical probability. By the end of Grade 10 (Key Stage 3), learners are expected to work with quadratic functions and equations, triangle congruence and similarity proofs, the laws of sines and cosines, and compound events in probability.
Disclaimer: exact competencies, content standards, and performance standards for a specific grade and quarter should always be checked against the official CG PDF, not summarized secondhand, since the full document runs to more than 70 pages of detailed tables.
What Is Vertical and Horizontal Articulation in the Math CG?
The CG describes two ways competencies connect across the curriculum, which it calls vertical and horizontal articulation. Vertical articulation concerns how knowledge in a single content domain builds year over year, for example how Key Stage 1's foundational number work in Grades 1-3 progresses into Key Stage 2's more complex operations, and eventually into Key Stage 3's algebra and functions. Horizontal articulation concerns how Math connects to other subjects in the same grade, such as how reading and writing numbers depends on foundational literacy skills from the Language CG, or how describing motion in Science requires the equation-solving skills taught in Math.
For teachers, horizontal articulation is a practical planning cue: a Grade 7 Science unit on motion, for instance, assumes learners can already solve the kind of equations covered in that grade's Math CG, so sequencing which subject teaches a shared skill first can matter for how smoothly a lesson lands.
Where Can Teachers Download the Official Math CG?
The current, complete file is hosted directly on deped.gov.ph as "9-FINAL-MATATAG-Mathematics-CG-2023-Grades-1-10.pdf," part of the Revised K to 10 Curriculum page. This single file covers all ten grades, which makes it easier to track vertical progression across key stages compared to English and Science, which DepEd splits into separate files by grade range.
An earlier, partial file limited to Grades 1, 4, and 7 (from MATATAG's Phase 1 rollout) still circulates on some school and third-party sites. It is not incorrect for those three grades specifically, but it is incomplete for a Grade 2, 3, 5, 6, 8, 9, or 10 class. Check the file title and grade range before treating a download as authoritative, and prefer the deped.gov.ph link over a reposted copy.
Tips for Teachers Using the Math CG
- Confirm you have the Grades 1-10 consolidated file, not the older Phase 1 file limited to Grades 1, 4, and 7, especially for Grade 6, 9, or 10 classes new to MATATAG this school year.
- Track vertical progression within a domain. Because Number and Algebra, Measurement and Geometry, and Data and Probability each run continuously from Grade 1 to Grade 10, it helps to read a domain's competencies across several consecutive grades rather than only the current one.
- Use the five proficiency strands as a lesson-planning check, not just a content checklist: does the lesson build conceptual understanding, procedural fluency, or both?
- Watch for terminology shifts from the 2016 CG, since Geometry and Measurement are now one domain, and Patterns/Algebra now sits inside Number and Algebra.
- Bookmark the deped.gov.ph source page, not just the PDF link, since DepEd occasionally reissues files with corrections under the same title.
