Unit I – Shape Areas

This maths scheme of work for Key Stage Two gets the children to develop and refine skills in measuring and calculating the areas and perimeters of geometric shapes including rectilinear and compound shapes. The class can identify how to use formulas to make it quicker and easier to calculate area.

Develop and refine skills in measuring and calculating the areas and perimeters of different geometric shapes including rectilinear and compound shapes

Lesson One : Matching Areas

Identify and record a selection of rectilinear shapes that have the same area when measured correctly in square centimetres

Lesson Two : Compound Shapes

Identify and record how to use the correct formulae to measure and calculate the correct areas of a range of different rectilinear shapes

Lesson Three : Shape Perimeters

Investigate and record a selection of rectilinear shapes that have the same matching perimeters but different areas using addition and multiplication calculation skills

Lesson Four : Triangle Squares

Explain and record how to measure the area of a right angled triangle by counting matching numbers of full and half squares as part of each shape’s area

  • Ordering and Changing

    Ordering and Changing

    Explore and record how to order three digit numbers by the place value of their digits and how the digits in a number change their numerical values when finding ten and one hundred more or less

  • Changing Hundreds

    Changing Hundreds

    Explore and record the matching number sums that are one hundred more and less than different three digit numbers to show changes to the place values of their numerical digits

  • Digit Changes

    Digit Changes

    Identify and record the matching number sums that are ten less than different three digit numbers by illustrating changes to the values of their hundreds, tens and ones digits

  • Changing Numbers

    Changing Numbers

    Identify and record number sums that are ten more than different three digit numbers using abacus diagrams to model their changing values
