Primary Grades 1–2: Building Strong Foundations

Grades 1 and 2 build upon the early literacy, numeracy, communication, and social skills developed during preschool and kindergarten.

Students focus on:

Developing reading fluency and comprehension.
Improving handwriting, sentence construction, and written expression.
Strengthening number recognition and basic mathematical operations.
Developing listening, speaking, and classroom communication skills.
Exploring introductory science and the environment.
Developing independence, cooperation, and positive study habits.

Primary Grades 3–6: Expanding Knowledge and Independence

As students progress through Grades 3–6, learning becomes more advanced and increasingly focused on independent thinking, comprehension, problem-solving, and applying knowledge in practical situations.

Students develop their abilities in mathematics, English Language Arts, science, technology, creativity, and analytical reasoning.

Our teachers encourage students to ask questions, communicate ideas clearly, work collaboratively, and take increasing responsibility for their learning.

English Language Arts and Literacy

Strong language skills are essential for academic success. Liberty International School's primary English program develops literacy and communication through structured instruction and regular practice.

English Language Arts includes five interconnected areas:

Reading: Fluency, comprehension, vocabulary, and interpreting written texts.
Writing: Sentence construction, grammar, spelling, composition, and written communication.
Speaking: Clear expression, presentations, discussions, and confidence communicating ideas.
Listening: Understanding instructions, explanations, discussions, and spoken language.
Viewing: Understanding and interpreting visual information and media.

Students engage in reading activities, vocabulary development, guided writing, comprehension exercises, and classroom discussions.

These activities help children develop the communication and analytical skills needed for continued academic achievement.

Mathematics: Understanding, Reasoning, and Problem-Solving

Mathematics at Liberty International School emphasizes conceptual understanding, logical reasoning, and applying mathematical knowledge to real-world situations.

We want students to understand how mathematics works, not simply memorize answers.

Mathematics Learning Objectives: Grades 1–3

During the early primary years, students work toward understanding foundational mathematical concepts, including:

Whole numbers and the four fundamental mathematical operations.
Number relationships, patterns, and sequences.
Money and practical mathematical applications.
Introductory fractions.
Measurement of time, length, mass, and capacity.
Two-dimensional and three-dimensional shapes.
Geometry, symmetry, and spatial relationships.
Collecting and representing simple data.

By the end of Grade 3, the curriculum aims to develop confidence working with whole numbers up to 10,000 and applying mathematics to increasingly complex problems.

Mathematics Learning Objectives: Grades 4–6

Upper primary mathematics develops greater depth and complexity, including:

Whole numbers, fractions, decimals, and percentages.
Ratios, proportions, and number relationships.
Multiplication, division, and multi-step calculations.
Measurement, perimeter, area, volume, and surface area.
Geometry involving angles, triangles, polygons, and circles.
Patterns, sequences, equations, and mathematical reasoning.
Statistics, probability, and interpreting graphs.
Practical problem-solving and mathematical communication.

Students are encouraged to explain their reasoning, recognize patterns, make connections, and apply mathematics to meaningful situations.

Science Education for All Primary Grades

Science is an important component of Liberty International School's international curriculum from Grade 1 through Grade 6.

Our science program encourages students to understand the natural world through observation, questioning, investigation, and evidence-based thinking.
