Constructing Triangles and Grade F E D C Constructing Triangles and Angle Facts I am able to draw and measure angles using a protractor. I can recognise and label types of triangle. I can recognise and label types of angles. I know that the sum of angles in a triangle is 180 degrees and the sum of the angles in a quadrilateral is degrees. I can calculate missing angles in triangles and quadrilaterals I can construct a triangle using a ruler and protractor. I can construct a triangle using a compasses.

Algebraic Fractions and Changing the Subject of a Formula Grade D C B A A* Algebraic Fractions and Changing the Subject of a Formula Solve linear equations where the variable occurs in the numerator of a fraction. I can rearrange simple formulae. I can rearrange more complicated formulae. I can combine algebraic fractions using the four rules of addition, subtraction, multiplication & division. I can rearrange a formula where the subject appears twice. I can simplify algebraic fractions by factorisation and cancellation. I can rearrange more complicated formulae where the subject may appear twice or as a power. I can solve a quadratic equation obtained from manipulating algebraic fractions where the variable appears in the denominator. Dialogue marking sheet.
