Lesson Note on Mathematics SS1 First term
Week 1 – Mensuration
Overview – What is mensuration? Mensuration is a branch of Mathematics that deals with the measurement of areas and volumes of various geometrical figures. This week, we shall learn about mensuration. We shall also learn about figures such as cubes, cuboids, cones and triangular prism as well as their volumes and areas. To learn more, Click here…
Week 2 – Volumes of Frustums of Cone, Rectangular-Based Pyramid and other Pyramids
Overview – Having been introduced to the concept of mensuration, this week, we shall learn about the shapes such as the cone, oblique prism, oblique cylinder and pyramids. We shall also learn how to prove that the sum of the angles in a triangle is 180 degrees. To learn more, Click here…
Week 3 – Geometrical Construction
Overview – Geometry is the branch of Mathematics that deals with the study of shapes, sizes, angles and the dimensions of objects, their spatial relationships and their properties. The week, we shall learn about geometrical construction. We shall learn how to construct basic shapes, lines and angles.

Week 4 – Triangle: Drawing and Bisection of Line Segment, Construction and Bisection of Angles
Overview – Having being introduced to geometry, this week, we shall learn how to draw and bisect line segment. Bisection means to divide the line segment in two equal parts. We shall also learn how to construct and bisect angles.

Week 5 – Construction: Construction of Quadrilateral Polygon, Construction of Equilateral Triangle Locus of Moving Points.
Overview – A quadrilateral polygon is a polygon with four sides, four vertices and four angles. Its four angles make up 360°. Equilateral triangle is a type of triangle with all its sides equal in length. It is also called an equiangular triangle because its angles are equal (60°). This week, we shall learn about the construction of shapes such as rectangle, kite, quadrilateral and equilateral triangle.

Week 6 – Deductive Proof: Sum of Angles of a Triangle Revision of Angles on Parallel Line Cut by a Transversal Line.
Overview – Just like regular numbers, angles can be added to obtain a sum, perhaps for the purpose of determining the measure of an unknown angle. This week, we shall learn how to calculate the missing angles of triangles.

Week 7 – Collection, Tabulation and Presentation of Grouped Data
Overview – In some investigations you may collect an awful lot of information. How can you use this raw data and make it meaningful? This section will help you to collect, organize and interpret the data efficiently. The easiest way to collect data is to use a tally chart. Ways of representing data include table, graphs and charts. The show the number of times a particular variable e.g. number of pets in a school, the term “frequency” is used. When a large amount of data has to be collected, use a grouped frequency distribution. This week, we shall learn about the collection, tabulation and presentation of grouped data.

Week 8 – Calculation of Range, Median and Mode of Ungrouped Data
Overview – The range of a set of data is the difference between the highest and lowest values in the set. Median is defined as the mid value of the data set. The mode is defined the value that most frequently occurs in the given data. This week, we shall learn about how to calculate the range, median and mode of ungrouped data.
