Having investigated where, why and how scale is used and expressed, I can apply my understanding to interpret simple models, maps and plans.

Key Learning Intentions

Learners’ Experiences / Possible ContextsConsider: collaborative learning, creativity, problem solving/investigative approaches, use of ICT, links across the curriculum etc.

Success Criteria Evaluation and Next Steps

Scale is the ratio between the size of something and a representation of it

We use scale: to fit a drawing of

a very large or small object onto one page,

to create a drawing which is proportionately the same as the object.

We use scale drawings in many real-life situations e.g. office plans, lego instructions, extensions, car design, maps

Scale can be expressed in the following forms:

1cm to 10m (which means that 1cm on the plan represents 10m in real life)

1:1000 (which

Discuss scale models, e.g. toy cars, doll’s house etc. Give pupils an appropriate scale (1cm to 10cm) and ask them to calculate true heights and lengths.

Pupils to measure simple objects, e.g. door, table top with objects, etc. then draw them to a given scale

Pupils make a scale drawing of their classroom and its contents.

Pupils make a 2D or 3D scale diagram of the planets during a Space Topic

Research the different scales of OS maps – ideal for motorists, town developers and architects

We use scale to interpret simple models, maps and plans e.g. what is the true length of the office, store?

We use scale to calculate the true length/height etc. of a real object.

I can use scale to interpret simple models, maps and plans.

I can use scale to calculate the true length/height of a real object.

I acknowledge the need for appropriate accuracy
