Seychelles Secondary 1 Curriculum - Mathematics

This curriculum outline is based on the "Mathematics Syllabus - S1-S3" document ( for the European Schools, which appears to be relevant to the Seychelles context. It is designed as a transitional year from primary to secondary mathematics.

Numbers:

• Natural and Integer Numbers: Understanding the difference between natural and integer numbers, including the concept of negative numbers and their application (e.g., debts and savings).
• Plotting Points: Plotting points on a plane with integer coordinates.
• Absolute Value: Understanding the absolute value of an integer, particularly negative numbers, in relation to the number line.
• Comparison and Ordering of Integers: Comparing and ordering sets of integer numbers, including the transitivity property of > and <.
• Prime Numbers, Factors, and Divisors: Understanding prime numbers, factors, and divisors, including prime factor decomposition. Writing natural numbers as a product of prime numbers. Exploring divisibility rules (2, 3, 5, 10). Finding the Lowest Common Multiple (LCM) and Highest Common Factor (HCF).
• Operations with Integers and Decimals: Adding, subtracting, multiplying, and dividing integers and decimals. Understanding the importance of 0 and 1. Applying the order of operations, including brackets.
• Fractions: Understanding fractions as ratios of two integers. Simplifying fractions and converting between fractions and terminating decimals. Ordering fractions and decimals.

Algebra:

• Formulae, Tables, and Graphs: Working with pictorial sequences (arithmetic only). Creating rules to determine the next term and general rules for arithmetic sequences. Substituting into general rules. Creating tables of values and plotting sequences.
• Expressions: Simplifying equivalent linear expressions.
• Equations: Solving simple linear equations.

Geometry:

• 3D Shapes: Recognizing, drawing, and sketching top and side views of 3D shapes (prisms, cylinders, pyramids, cones, and spheres). Classifying 3D shapes based on faces, edges, vertices, parallelism, and perpendicularity. Drawing 3D shapes (cubes and cuboids by hand, others with CAD software). Recognizing and constructing nets of prisms and pyramids.
• 2D Shapes: Recognizing and naming 2D shapes (triangles, quadrilaterals, regular polygons up to decagon, circle). Classifying 2D shapes based on parallelism, perpendicularity, and equality of sides.
• Lines and Angles: Measuring and constructing line segments and angles using a protractor and set-square. Constructing parallel and perpendicular lines, and perpendicular bisectors. Constructing angles of a given size.
• Triangles: Constructing triangles given SSS, SAS, SSA, and ASA conditions.
• Orientation and Navigation: Using compass directions and distances to locate positions. Developing the concept of an angle through turns.
• Measurements: Understanding the distinction between geometrical objects and their measures (e.g., segment and length, angle and size). Estimating and measuring lengths. Developing the concept of area and volume using unit squares and cubes. Calculating perimeters and areas of squares and rectangles. Converting units of length and mass.

Set Theory:

• Basic Concepts: Understanding sets, elements, universal set, empty set, union, intersection, and complement.
• Venn Diagrams: Drawing and interpreting Venn diagrams to show logical relationships.
• Symbols: Using set theory symbols appropriately.
