What a brilliant site you have!!! I love it, especially as it saves me hours and hours of hard work. Others who haven't found your site yet don't know what they are missing!

It is quite frankly the best money I have ever spent on my child. I really cannot thank you enough for providing this, it really is brilliant.

You have the most amazing program. Everybody loves it and the student's results have been in the high 90%'s, it's definitely due to your program.

  • KS2.Y5 – KS2 Year 5
    • Year 5 programme of study
      • KS2.Y5.M – Measurement

        • Pupils should be taught to:

          • KS2.Y5.M.7 – Use all four operations to solve problems involving measure [for example, length, mass, volume, money] using decimal notation, including scaling

  • Year 5
    • Measurement and Geometry
      • Using units of measurement

        • ACMMG109 – Calculate the perimeter and area of rectangles using familiar metric units

  • Year 6
    • Measurement and Geometry
      • Using units of measurement

        • ACMMG137 – Solve problems involving the comparison of lengths and areas using appropriate units

  • Year 7
    • Measurement and Geometry
      • Using units of measurement

        • ACMMG159 – Establish the formulas for areas of rectangles, triangles and parallelograms and use these in problem solving

  • 7 – Year 7
    • 7.GM – Geometry and measurement
      • 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

  • 3 – Grade 3
    • 3.MD – Measurement & Data
      • Mathematics

        • 3.MD.7 – Relate area to the operations of multiplication and addition.

          • 3.MD.7.b – Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving real world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning.

  • 5 – Grade 5
    • 5.NF – Number & Operations—Fractions
      • 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.
