2. 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

3. 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

4. Planning for quality outcomes / teaching Strategies that develop:- Design skills / ‘Thinking skills’; Manufacturing skills / quality experiences; Graphical skills; Understanding of the electrical Systems.

5. Planning for quality outcomes / teaching Strategies that develop:- Design skills In 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?

6. Planning for quality outcomes / teaching Strategies that develop:- In your groups/pairs discuss and evaluate:- each others finished product against the mark indicators/descriptors.

8. Tolerance - critical dimension. Manufacturing-aids?

9. Points to consider: Is the project appropriate to the age group? Skills development / Assessment? Pupils skills and capabilities; Manufacturing – aids? Constraints - Internal radii, cost….
