Main methods of calculating using natural numbers and simple numbers in decimal form when calculating approximations, mental arithmetic, and calcuĀ lations using written methods and calculators. Using the methods in different situations.
Plausibility assessments when estimating and making calculations in everyday situations.
Basic geometrical objects such as polygons, circles, spheres, cones, cylinders, pyramids, cuboids and their relationships. Basic geometrical properties of these objects.
Construction of geometrical objects. Scale and its use in everyday situations.
Symmetry in everyday life, in arts and nature and how symmetry can be constructed.
Methods for determining and estimating circumference and areas of different two-dimensional geometrical gures.
Comparing, estimating and measuring length, area, volume, mass, time and angles using common units of measurement. Measurements using contemporary and older methods.
Lesson: Area and Circumference of a circle - Google slides (Explaining step by step and providing examples and exercises for students) Work in Class: Support: Extension: The distance around the wheel of a truck is 9.42 feet. What is the diameter of the wheel? A lawn sprinkler sprays water 5 feet in every direction as it rotates. What is the area of the sprinkled lawn? A dog is tied to a wooden stake in a backyard. His leash is 3 meters long and he runs around in circles pulling the leash as far as it can go. How much area does the dog have to run around in? A spinner has 6 sectors, half of which are red and half of which are black. If the radius of the spinner is 3 inches, what is the area of the red sectors?
Continuation of last lesson on Surface Area and Perimeter of Circles but adding Area and Perimeter of a Sector as well as Compound Shapes with circles.
Lesson:
Area and Circumference of a circle - Google slides (Explaining step by step and providing examples and exercises for students). START AT SLIDE 9 and END AT SLIDE 21!
Worksheets:
2. Area and Perimeter of a Sector
Objective (Teaching Point): 1. The student will have a better understanding of cubes and other three-dimensional objects. 2. The student will be able to find the volume of cubes. 3. The student will be able to identify cubes all around them.
Starter:
Find the perimeter and the area of:
A. square with s = 3,5m
B. rectangle with l = 12,3 and w = 5,6.
An equilateral triangle has perimeter of 125cm. Find the sides and the angles.
Lesson:
Definition: Volume is the amount of space a 3D object takes up. It is measured in cubic units. Cm3 or m3. Pronounced centimetres cubed or meters cubed.
Formula (cube, rectangular prism): Volume=length x width x height.
Display the link below:
Model how to calculate the volume. Show another cube and have the class work out the Volume
This lesson will be used to review skills learned in geometry on how to solve area and perimeter of different shapes.
