Term 2 Week 2

Knowing Geometry is critical to many forms of construction

This week we continue exploring Geometrical figures - we have looked at parallel lines, and the angles made by a third line crossing them, now we move on to defining and understanding triangles.

The various options all have mathematical names:

If all three sides are different lengths, it is a 'Scalene'
If two sides are the same length it is 'Isosceles'
If all three sides are the same it is 'Equilateral'
If all angles are <> 90 (blunt looking) then it is 'Obtuse-angled'
If one angle is = 90 then it is a 'Right-angled' triangle

Students also should discover that the angles inside ALL triangles always add up to 180 degrees.

Students should be able to identify the different types and solve problems based on the properties of each type. For example if a triangle has two sides the same, and the angle between those sides is 40 degrees, then from the knowledge of Isosceles triangles students should be able to work out that the other two angles are the same, and that they are equal to 70 degrees.

Term 2 Week 1

15th century (made up) depiction of Euclid

Welcome back to maths in term 2!

Geometrical Figures is our new topic.

Over the next week students should be able to name different types of angles, and solve geometric puzzles by using the properties of angles, triangles and parallel lines.

Much of this was put together by the Greek mathemtician Euclid about 2300 years ago. Euclid's approach was to work from a small number of foundational 'facts' (called 'axioms') and solve problems by using logic and reason to build answers by combining the axioms.

Week 10

Class 8 have completed their Algebra revision, and have now all done the Algebra topic test. The test results should be available this Thursday. This ends our work with Algebra for this year in middle lessons. The topic will be revisited in more detail in Term 1 2008.

The next topic is Geometrical figures - angles, parallel lines, triangles, quadrilaterals and polygons. This will build on last years geometry main lesson.

This being the last week of term, there is no assignment! Enjoy the holidays, and we will continue the maths next term!
