AREA OF CIRCLE LESSON NOTE AND LESSON PLAN FOR PRIMARY AND SECONDARY SCHOOLS AND HIGH SCHOOLS

Days W.A..L.T:  Content  Starter  Class activities Plenary  Homework  Monday  Meaning of circle and  parts of a circle Resources  a cardboard with circle drawn on it   A circle is a perfect round plane.  Examples of circle are; coins, wheels, rings, tin tops and bottom of buckets. Parts of a Circle. Centre: the point at the middle of the circle. Circumference: is the curved outer edge of the circle. (the distance round the circle ). It is the longest part of a circle. Diameter: the line from a side through the centre to another side. It divides the circle to equal halves. Half of a diameter is a radius. Radius: is any straight line drawn from the centre to the circumference. Semi-circle: half of a circle. Quadrant : is a quarter part of a circle. Chord: a straight line joining two points on the circumference. ( a chord does not divide a circle into equal halves like the diameter) Sector: is a region between two radii and the circumference. Begin the lesson by drawing a circle on the b

AREA AND PERIMETER OF PLANE SHAPES LESSON NOTE AND LESSON PLAN FOR PRIMARY, SECONDARY AND HIGH INSTITUTIONS

W.A.L.A: AREA AND PERIMETER OF PLANE SHAPES  Monday    Area  of rectangles and squares Resources  Content  The area of any given shape is the measure of the extent of a surface. Area is measured in square units. The perimeter of any given shape is the sum of the distance of all the lengths of the sides of that shape. Examples:  Find the area of a rectangle whose length is 6cm and width 4cm. A rectangle is 10m long and 7m wide. What is the area? Solution  Area = L X B         = 6cm X 4cm          = 24 cm² Area = L X B          = 10 m X 7 m          = 70 m² Area of Square  Area of square = L²  or S². where L= length and S = sides Examples: Calculate the area of these squares with the following sides.  7 cm   9 m Solution  Area = L²           = 7cm X 7cm           = 49cm² Area = S²              = 9m  X 9m                      = 81m² Pupils should be Able to ; Find the area rectangles and squares 

METRIC WEIGHT LESSON PLAN AND LESSON NOTE FOR PRIMARY, SECONDARY AND HIGH SCHOOLS

SUBJECT: MATHEMATICS                W.A.L.A:  METRIC WEIGHT                                                                 Day s W.A..L.T:  Content  Plenary  Starter  Task  Homework  Monday   To measure weight of various objects. Convert units of weights Resources  Inside out  Learn   mathematics Book 6, page  42 Weighing balance, scale balance, stones, and bottles. INTRODUCTION TO METRIC WEIGHT The heaviness of an object tells us what weight is. There are various objects for measuring weight such as the scale balance, the weighing and the spring balance. The basic unit of measuring weight is gram (g). The weight of heavy objects like bags of cement are measured in kilograms while light objects like pen, pencil are weighed in grams. CONVERSION OF METRIC METRIC WEIGHT 10 milligrams (mg) = 1 centimeter (cg)  10 centigrams = 1 decigrams (dg)  10dg = 1 gram (g)  100cg = 1g 1000g = 1 kilogram (g) 1000kg = 1 ton (t)   Pupils should be Able to ; Define weight, find the various units of measu

METRIC LENGTH LESSON PLAN AND LESSON NOTE FOR PRIMARY, SECONDARY AND HIGHER INSTITUTIONS

SUBJECT : MATHEMATICS                W.A.L.A:  METRIC LENGTH                                                                                      Days W.A..L.T:  Content  Plenary  Starter  Task  Homework  Monday   To measure length of various objects. Convert units of length Resources  Inside out  Learn   mathematics Book 6, page  35 Ruler, Tape rule, meter rule.  METRIC LENGTH Length is a measurement that tells how long or wide something is.  In the olden days people measure length of objects by using various parts of the body such as arm, foot, palms etc. But all these does not give accurate measurements.  Today people use instruments like ruler, tape rule, meter tape to accurately measure the length of objects. The standard unit of length measurements s metre (m)  CONVERSION OF METRIC LENGTH  10 millimetres (mm) = 1 centimeter (cm)  10 centimeters = 1 decimetre (dm)  10dm = 1 meter (m)  1000mm = 1m 100cm = 1m 1000m = 1 kilometer (km)  Examples Solutions  a. The length of line a is 6
