We

Are

Learning

To

• Understand symmetry;• use a template;• work accurately to a line

This is because…

When making products we often need to make patterns that are the same shape on each side of a centre line.

We can use patterns or templates to make copies from other materials.

Remember to:

Cut and work as accurately to the template or line and at all times leave the line on!

Symmetry

Template

Success Criteria!

WILF: What I’m Looking For?

We will be able to: -

1.Sketch a simplistic profile / shape of template

2.Cut-out the template accurately ‘leaving lines ‘on’

3.File accurately leaving ‘all lines-on’

4.Work to a critical dimension/tolerance +/-

5.Produce a quality finish on the edge ‘no file marks’

Theme: Lady Birds & Butterflies

Planning for quality outcomes / teaching Strategies that develop:-

• Design skills / ‘Thinking skills’;• Manufacturing skills / quality experiences;• Graphical skills;• Understanding of the electrical Systems.

Planning for quality outcomes / teaching Strategies that develop:- Design skillsIn your groups/pairs discuss and show:-

• An alternative symmetrical profile shape/template; • how the motor is attached to the body;• how the switch is attached?• How will we get the bug to ‘jitter’/vibrate?

Planning for quality outcomes / teaching Strategies that develop:-In your groups/pairs discuss and evaluate:-

• each others finished product against the mark indicators/descriptors.
