  • Example: What is 20% of 150? (Solution: 30)
  • Example: If a shirt costs $25 and is reduced by 15%, what is the new price? (Solution: $21.25)

• Ratios and Proportions: Understanding and working with ratios (comparing quantities) and proportions (equal ratios) is a crucial skill.

  • Example: Simplify the ratio 15:25. (Solution: 3:5)
  • Example: If 3 apples cost $1.50, how much would 5 apples cost? (Solution: $2.50)

Algebraic Expressions and Equations:

• Algebraic Expressions: Students learn to simplify and evaluate algebraic expressions involving variables and numbers.

  • Example: Simplify 3x + 2y - x + 5y. (Solution: 2x + 7y)
  • Example: If x = 4 and y = 2, evaluate 2x + 3y. (Solution: 14)

• Equations: Solving simple linear equations (equations with one variable) is a key component of Year 7 algebra.

  • Example: Solve for x: x + 5 = 12. (Solution: x = 7)
  • Example: Solve for y: 2y - 3 = 7. (Solution: y = 5)

Measurement and Geometry: Exploring Shapes and Space

This section covers geometric concepts and their application in measurement problems.

Shapes and Angles:

• Shapes: Year 7 students learn about different types of shapes, their properties (e.g., number of sides, angles), and how to classify them (e.g., triangles, quadrilaterals, polygons). They work with identifying and classifying angles (acute, obtuse, right, reflex).

  • Example: What type of triangle has two equal sides? (Solution: Isosceles triangle)
  • Example: What is the sum of the interior angles in a quadrilateral? (Solution: 360 degrees)

• Angles: Students develop skills in calculating angles using various geometric principles, including angles on a straight line, angles at a point, vertically opposite angles, and angles in triangles and quadrilaterals.

  • Example: Two angles are on a straight line. One angle measures 70 degrees. What is the measure of the other angle? (Solution: 110 degrees)
  • Example: Find the missing angle in a triangle if two angles measure 45 degrees and 60 degrees. (Solution: 75 degrees)

Area, Perimeter, and Volume:

• Area: Students learn to calculate the area of various shapes, including rectangles, squares, triangles, parallelograms, and circles.

  • Example: What is the area of a rectangle with length 8cm and width 5cm? (Solution: 40 cm²)
  • Example: Calculate the area of a triangle with base 10cm and height 6cm. (Solution: 30 cm²)

• Perimeter: Calculating the perimeter (distance around) of different shapes is another important skill.

  • Example: What is the perimeter of a square with side length 7cm? (Solution: 28cm)
  • Example: Find the perimeter of a rectangle with length 12cm and width 8cm. (Solution: 40cm)

• Volume: Students are introduced to the concept of volume (the amount of space a 3D shape occupies) and how to calculate it for simple shapes like cubes and rectangular prisms.

  • Example: What is the volume of a cube with side length 4cm? (Solution: 64 cm³)
