LNF Cymru Literacy and numeracy for Wales

VCSE Built Environment

VCSE Built Environment asks learners to read a Welsh case study and technical documents such as briefs and risk assessments, to justify choices of sites, methods and materials in writing, and to evaluate their own practical work using accurate trade terms. Its numeracy is mostly practical and sits in the 60% Unit 3, with accurate measuring to tolerances, reading plans and drawings, mixing to ratios and estimating quantities, alongside cost, time and carbon comparisons and project timelines in Unit 2. The single biggest thing KS3 should build is accurate measuring and marking out in millimetres from a drawing, checked against a stated tolerance.

Skills that use Strategic competence

  1. Measuring, marking out and working to tolerances

    Assessed: In coursework (non-examination assessment, NEA)

    Learners must measure and mark out accurately with tools such as a tape measure, spirit level, chalk line or laser level, and follow dimensions and tolerances in every trade activity. Work must be level, plumb and square, and is checked at each stage to find and correct errors.

    Numeracy: Measurement, Angle, The number system, Strategic competence, Communicating with symbols

    Getting pupils ready

    Year 7
    Pupils measure and mark a piece of card or timber to the nearest millimetre with a steel rule, then check a partner's marks.
    Year 8
    Pupils use a spirit level and tape measure to check whether shelves and window sills around school are level, recording readings in millimetres and converting them to centimetres and metres.
    Year 9
    Pupils make a simple frame from a drawing with a tolerance of plus or minus 2 mm, measure the finished piece, and record whether each dimension is within the upper and lower limits.
