Constructions and accurate drawings lesson (lines, angles, perpendicular/angle bisector, triangles)

This is a powerpoint and workbooklet for constructions and accurate drawings where students will learn how to recap how to construct lines, angles, circles and triangles using a ruler and protractor. Then they will move onto constructing perpendicular bisectors and angles.

This is a time saving resource for busy teachers. You should be able to teach a lesson with hardly any preparation (mainly printing and maybe some cutting!).

Fully differentiated objectives:

Blue: Draw accurate lines, angles, circles and triangles (using ruler and protractor)
Gold:Construct perpendicular bisectors (including through a point)
Red:Construct angle bisectors
Challenge (Purple): construct a triangle using a compass (this is not on the powerpoint and is an independent task for students to see if they can work it out)

This resource includes:
• A PowerPoint
• A differentiated Work booklet that includes self-assessment sections
• Answers ( I recommend printing them onto tracing paper as it is very easy to mark then!)
• 3 foldable how to guides for how to do constructions (perpendicular bisector, perpendicular bisector through a point, angle bisector). This is for students to have some independent learning/to help with revision in place of putting it all on the powerpoints. See the preview pictures for what they look like.

The PowerPoint includes the following format (watch the preview video Here):
• Objective and levels
• A “how to teaching portion” with animated examples
• Plenary (with answers)

Recommendations:

• Print off the 3 per page foldables on different colours for different topics (see the cover image for an example) -This will involve some extra preparation from the teacher
• Print off the 3 topics on one page foldables on white and students can colour the titles in and cut out the foldables themselve - less preparation for the teacher

The powerpoint and booklet are currently set up for GCSE maths grades, however you can edit the grades to reflect KS3 or your own schools assessment criteria. In the word booklet if you change any grade (e.g the blue section) it should automatically change the rest of that colour into the same grade.

This will take up a whole lesson at least.
