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.

  • KS1.Y1 – KS1 Year 1
    • Year 1 programme of study
      • KS1.Y1.M – Measurement

        • Pupils should be taught to:

          • KS1.Y1.M.1 – Compare, describe and solve practical problems for:

            • KS1.Y1.M.1.a: lengths and heights [for example, long/short, longer/shorter, tall/short, double/half]

          • KS1.Y1.M.2 – Measure and begin to record the following:

  • Year 1
    • Measurement and Geometry
      • Using units of measurement

        • ACMMG019 – Measure and compare the lengths and capacities of pairs of objects using uniform informal units

  • 2 – Year 2
    • 2.GM – Geometry and measurement
      • 2.GM.1 – Compare the lengths, areas, volumes or capacities, and weights of objects and the durations of events, using self-chosen units of measurement

  • 3 – Year 3
    • 3.GM – Geometry and measurement
      • 3.GM.1 – Measure the lengths, areas, volumes or capacities, and weights of objects and the duration of events, using linear whole-number scales and applying basic addition facts to standard units

  • K – Kindergarten
    • K.MD – Measurement & Data
      • Mathematics

        • K.MD.1 – Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object.

        • K.MD.2 – Directly compare two objects with a measurable attribute in common, to see which object has “more of”/“less of” the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.

  • 1 – Grade 1
    • 1.MD – Measurement & Data
      • Mathematics

        • 1.MD.1 – Order three objects by length; compare the lengths of two objects indirectly by using a third object.

        • 1.MD.2 – Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.

  • 2 – Grade 2
    • 2.MD – Measurement & Data
      • Mathematics

        • 2.MD.2 – Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.
