Venezuela Primary School Curriculum - Mathematics (4th Grade)

This information is based on the 2007 Currículo del Subsistema de Educación Primaria Bolivariana.

The mathematics curriculum for 4th grade emphasizes the interconnectedness of mathematics with other sciences and its application to real-world problems. The curriculum aims to develop logical thinking, problem-solving skills, and an understanding of mathematical concepts through various learning experiences and activities.

Number Sense and Numeration:

• Interpreting and recoding natural numbers less than 1,000,000 based on place value.
• Identifying and interpreting ordinal numbers up to one million.
• Interpreting and formulating sequences with natural numbers less than one million using two criteria.
• Identifying and interpreting prime and composite numbers.
• Understanding decimal numbers.
• Ordering natural and fractional numbers using the symbols >, <, and =.
• Reading and writing natural numbers, integers, and decimal numbers.
• Working with Roman numerals.
• Understanding the relationship between fractions and division, and multiplication and division.
• Identifying the nearest hundred or ten for a natural number less than one thousand.
• Interpreting positional values of numbers less than one million.

Fractions:

• Interpreting and representing proper and improper fractions.
• Performing addition and subtraction of heterogeneous fractions.

Geometry and Measurement:

• Identifying and constructing coordinate systems.
• Graphing geometric figures in the first quadrant of the Cartesian plane.
• Identifying and graphing axes of symmetry of plane geometric figures (isosceles triangle, square, rectangle, rhombus, circle, trapezoid).
• Identifying and graphing parallelograms.
• Transforming plane geometric figures: translation, enlargement, and reduction.
• Calculating and estimating the perimeter of geometric figures in official units of measurement (m, dm, cm).
• Calculating the area of a rectangle and a square in estimated square units of measurement.
• Graphing secant lines.
• Identifying and measuring angles using geometric instruments.
• Solving problems involving the measurement and comparison of cube volumes in cubic centimeters.
• Solving problems involving time duration using time references.
• Working with the school calendar and time allocation.
• Solving problems related to setting times and durations of events in relation to time references of the hour.
• Estimating expenses using currency.

Statistics:

• Interpreting and representing statistical data in various types of graphs.
• Identifying predictable phenomena and random phenomena.
• Predicting states of matter based on temperature variations.
• Analyzing data: mode and average.
• Solving everyday problems using statistics.

Mathematical Operations:

• Performing addition, subtraction, multiplication, and division operations with natural numbers up to one million.
• Applying properties of addition, subtraction, and multiplication.
• Solving problems involving combined operations (addition, subtraction, multiplication, and division) with natural numbers less than 10,000.
• Applying the rule of three, percentage, and least common multiple.

Natural Sciences and Society:

The curriculum integrates natural sciences with mathematics through the exploration and application of mathematical processes and scientific concepts to real-world situations. This includes topics such as the environment, the human body, health and hygiene, and experimentation. The focus is on developing an understanding of scientific concepts and their application to everyday life, promoting critical thinking, and fostering environmental and health awareness. Specific content examples include:

• Understanding the biosphere and its degradation.
• Investigating the Earth's layers.
• Differentiating between plant and animal cells.
• Investigating reproduction in living beings.
• Understanding the water cycle and atmospheric cycle.
• Identifying evidence of pollution and promoting prevention strategies.
• Studying the human body as a system, including the brain, nervous system, and sensory organs.
• Understanding nutrition, digestion, respiration, and the circulatory system.
• Investigating diseases and their causes.
• Experimenting with properties of matter, energy transfer, magnetism, and natural phenomena.
• Exploring technological objects and their functions.
• Creating and building replicas of simple toys.
• Building objects for simple experiments.

This curriculum aims to equip students with the necessary mathematical and scientific knowledge and skills to analyze and solve real-world problems, fostering critical thinking and promoting responsible citizenship.
