What Grade 1 Mathematics covers under MATATAG
Under the DepEd MATATAG curriculum, Grade 1 Mathematics was rolled out in the first phase (School Year 2024–2025). The curriculum is organized around three content domains — Number and Algebra; Measurement and Geometry; and Data and Probability — and develops mathematical proficiency through five strands: conceptual understanding, procedural fluency, strategic competence, adaptive reasoning, and a productive disposition toward mathematics.
The summary below is contextualized to the official DepEd competencies for Grade 1 Mathematics; it is not a re-hosting of the Curriculum Guide. The authoritative document is the DepEd MATATAG Mathematics Curriculum Guide (Grades 1, 4, and 7), linked in the sources.
Quarter 1
Quarter 1 opens with simple 2-dimensional shapes (triangle, rectangle, square) and their features, alongside whole numbers up to 100, ordinal numbers up to 10th, and addition of numbers with sums up to 20.
Representative competencies: identify 2-D shapes in different sizes and orientations; count up to 100, including identifying one more or one less than a given number; use ordinal numbers up to 10th to describe position; and illustrate addition with sums up to 20 using concrete and pictorial models.
Quarter 2
Quarter 2 introduces measuring length and distance using non-standard units, place value in any 2-digit number, and addition of numbers with sums up to 100 without regrouping.
Representative competencies: measure the length of an object and the distance between two objects using non-standard units; and determine the place value of a digit in a 2-digit number, the value of a digit, and the digit given its place value.
Quarter 3
Quarter 3 covers representing data in a pictograph without a scale, subtraction of numbers that are both below 100 without regrouping, and repeating patterns.
Representative competencies: present, interpret, and organize data in a pictograph without a scale; and determine the next terms in a repeating pattern, using numbers or letters.
Quarter 4
Quarter 4 brings together fractions 1/2 and 1/4, Philippine coins and bills up to PHP 100 with addition and subtraction of money, half and quarter turns (clockwise and counter-clockwise), and telling time.
Representative competencies: illustrate and compare 1/2 and 1/4 as parts of a whole using models; recognize coins and bills up to PHP 100 and determine their value; and read and write time by the hour, half hour, and quarter hour on an analog clock.
Content domains and standards
Across the year, the three domains — Number and Algebra, Measurement and Geometry, and Data and Probability — recur with grade-appropriate content. Each quarter pairs content standards (what learners should know and understand) with performance standards (what they should be able to do), so that, for example, by the end of Quarter 1 learners can identify 2-D shapes, represent and compare whole numbers up to 100, and add with sums up to 20.
Planning MATATAG-aligned Grade 1 Mathematics lessons
Knowing the competencies is the start; building lessons and assessments around them every week is the work. With AcadiumLab, you pick a Grade 1 Mathematics competency and it drafts a full MATATAG-phase-structured lesson plan you can edit and approve, contextualized to DepEd competencies through a curriculum-graph (RAG) engine, plus a matching quiz across seven question types.
Rather than downloading a static file, the generated plan starts a loop: the work it produces feeds per-question analytics and a weekly picture of which pupils are keeping up. For the exact competency wording in any quarter, the official Curriculum Guide is linked below.
What are the topics in Grade 1 Mathematics under the MATATAG curriculum?
Grade 1 Mathematics spans three domains across the year. Quarter 1 covers 2-D shapes, whole numbers up to 100, ordinal numbers, and addition with sums up to 20; Quarter 2 covers measuring length with non-standard units, place value, and addition up to 100 without regrouping; Quarter 3 covers pictographs without a scale, subtraction without regrouping, and repeating patterns; Quarter 4 covers fractions 1/2 and 1/4, Philippine money up to PHP 100, half and quarter turns, and telling time.
What are the content domains in MATATAG Grade 1 Mathematics?
Three: Number and Algebra; Measurement and Geometry; and Data and Probability. The curriculum also develops five proficiency strands — conceptual understanding, procedural fluency, strategic competence, adaptive reasoning, and a productive disposition.
