Area and perimeter of figures on grids<\/strong><\/h2>\n\n\n\n

Key Notes :<\/p>\n\n\n\n

Area:<\/h3>\n\n\n\n
    \n
  1. Definition<\/strong>: Area is the amount of space inside a shape, measured in square units (like square centimeters or square inches).<\/li>\n\n\n\n
  2. Counting Squares<\/strong>: On a grid, students learn to count the number of unit squares inside a shape to find its area.<\/li>\n\n\n\n
  3. Formula<\/strong>: Area can also be found using the formula:Area=length\u00d7width .This formula applies to rectangles and squares.<\/li>\n\n\n\n
  4. Irregular Shapes<\/strong>: For irregular shapes on a grid, students can break down the shape into smaller rectangles or squares and add their areas together.<\/li>\n<\/ol>\n\n\n\n

    Perimeter:<\/h3>\n\n\n\n
      \n
    1. Definition<\/strong>: Perimeter is the distance around the outside of a shape.<\/li>\n\n\n\n
    2. Counting Sides<\/strong>: On a grid, students count the number of unit squares along the boundary of the shape to find its perimeter.<\/li>\n\n\n\n
    3. Formula<\/strong>: For rectangles and squares, perimeter is calculated using Perimeter=2\u00d7(length+width).<\/li>\n\n\n\n
    4. Units<\/strong>: Perimeter is measured in the same units as the sides of the shape (e.g., centimeters, inches).<\/li>\n<\/ol>\n\n\n

      Key Skills and Practices:<\/h3>\n\n\n\n
        \n
      1. Drawing Shapes<\/strong>: Practice drawing shapes on grids accurately.<\/li>\n\n\n\n
      2. Measuring<\/strong>: Use rulers or grid lines to measure sides precisely.<\/li>\n\n\n\n
      3. Calculating<\/strong>: Apply formulas correctly to find both area and perimeter.<\/li>\n\n\n\n
      4. Problem Solving<\/strong>: Solve word problems that involve finding area and perimeter of figures on grids, which may include real-world applications.<\/li>\n<\/ol>\n\n\n\n
