Grade 7 • Develop and apply a formula for determining the area of rectangle.( b * h) • Illustrate and explain how the area of a rectangle can be used to determine the area of a triangle.( ½ * b * h ) • Identify and plot points in the four quadrants of a Cartesian plane.
Grade 8 Pythagorean theorem • Solve Pythagorean Problems • Measure of the third side of right triangles • Model, explain, concretely, pictorially the Pythagorean theorem • Solve a given problem that involves Pythagorean triples e.g. ( 3 , 4 , 5 ) or ( 5, 12, 13)
Grade 9 • Old curriculum SIN, COS, TAN RATIOS which are shifted to grade 10 now. • New curriculum ( only Pythagorean Theorem) Solve problems and justify the solution strategy using circle properties e.g. Atangent to a circle is perpendicular to the radius at the point of tangency A 90 B
Grade 10 A & W • The Pythagorean Theorem • Sine, Cosine and Tangent Ratios • Solving Right Triangles only
Grade 11 A& W • Solve a contextual problem that involves angles of elevation or angles of depression. • Solve a contextual problem that involves two or three right triangles, using the primary trigonometric ratios
Grade 12 A & W • Sine law and cosine law. • Excluding the ambiguous case.(which are included in grade 11 Pre cal. and Foundation.) • Describe the use of the sine law and cosine law in construction, industrial, commercial and artistic applications.
Grade 10 Found & Pre Cal • Sine, Cosine Ratios & Tangent Ratio • Solving Right Triangles
Difference between 10 A & W and Foundation • Almost same but…. In A & W • Still developing the concept of right triangles and Pythagorean Theorem. • Applying similarity to right triangles • Generalizing patterns from similar right triangle(set of similar right triangles, that the ratios of the length of the side opposite to the length of the side adjacent are equal) • Relates every example somehow with trades
Grade 11 Foundations • Cosine law and the sine law. • Including the ambiguous case. In which they.. • Draw a diagram to represent a problem that involves the cosine law or sine law. • Explain, concretely, pictorially or symbolically, whether zero, one or two triangles exist, given two sides and a non-included angle. • Solve a problem involving the sine and cosine laws that requires the manipulation of a formula. • No reference angle (which are in Pre cal)
Grade 12 Foundations • Sinusoidal functions in which • Represent data • Describe the characteristics • Graph data • Interpret data • Contextual problem
Grade 11 Pre Cal • Angles in Standard position • Reference angle • Determine the quadrant in which a given angle in standard position terminates. • Illustrate that the points on Cartesian plane P ( x, y) , P (−x, y) , P (−x,− y) and P (x,− y) are points on the terminal sides of angles in standard position that have the same reference angle. cont…
