Knowledge, skills and understanding
Understanding measures
KS2.Ma3.4 – Pupils should be taught to:
KS2.Ma3.4.e – Find perimeters of simple shapes; find areas of rectangles using the formula, understanding its connection to counting squares and how it extends this approach; calculate the perimeter and area of shapes composed of rectangles.
Samples: Measure using square centimetres. Calculating perimeter tutorial. Calculating Perimeter using Metres tutorial.
Using and applying shape, space and measures
KS2.Ma3.1 – Pupils should be taught to:
Problem solving
KS2.Ma3.1.b – Select and use appropriate calculation skills to solve geometrical problems
Samples: Measuring length in metres tutorial. Measure using square centimetres.
Using units of measurement
ACMMG137 – Solve problems involving the comparison of lengths and areas using appropriate units
Samples: Calculating Perimeter using Metres tutorial. Fractions, Length and Division.
Using units of measurement
ACMMG159 – Establish the formulas for areas of rectangles, triangles and parallelograms and use these in problem solving
Samples: Calculating area using a grid. Calculating the Area of Irregular Shapes. Area of Squares and Rectangles.
7.GM.3 – Use side or edge lengths to find the perimeters and areas of rectangles and parallelograms and the volumes of cuboids, given whole-number dimensions
Samples: Calculating Perimeter using Metres tutorial. Calculating area using a grid. Area in daily use.
Mathematics
6.G.1 – Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems.
Samples: Calculating the Area of Irregular Shapes. Calculating area using a grid. Area in daily use.
Mathematics
3.MD.7 – Relate area to the operations of multiplication and addition.
3.MD.7.d – Recognize area as additive. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real world problems.
Samples: Calculating the Area of Irregular Shapes. Arrays. Calculating the Area of Irregular Shapes tutorial.
Mathematics
5.NF.4 – Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.
5.NF.4.b – Find the area of a rectangle with fractional side lengths by tiling it with unit squares of the appropriate unit fraction side lengths, and show that the area is the same as would be found by multiplying the side lengths. Multiply fractional side lengths to find areas of rectangles, and represent fraction products as rectangular areas.
Samples: Arrays. Area in daily use. Calculating area using a grid. Calculating the Area of Irregular Shapes.
