Graded examples of solving quadratics using intersections of line and curve, from finding intersections of given line and curve, to plotting both line and curve and then finding intersections.

For the given shapes, change the subject of the standard area and volume formulae

Practice in using the two formulae related to arithmetic series - values of three variables are given and the other two have to be calculated by substitution into the appropriate formula. If printed two sheets to a page, will produce four student copies per A4 sheet.

<p>Two 3-d shapes with lengths given algebraically. Challenge is to find surface area and volume for each shape in terms of x. Requires bracket expansions of two and three bracket expressions and significant simplification of expressions. Created for top set year 9 as classwork. Worked solutions on separate slides.</p>

Powerpoint containing questions for small group or class discussion to introduce the effect of multiple and repeated percentage change (ie what is overall impact of 20% increase then 20% decrease?).

Complete the table by rearranging the equations into y=mx+c form. Then establish which pairs of lines are parallel and perpendicular. Finally, complete the last two rows by entering equations of two new lines parallel to the suggested lines.

Students need to decide whether given formulae are valid rearrangements of the original formula given - includes many common mistakes made by students

Activity for pupils to consider and calculate the length, area and volume dimensions of scale models of the Olympic Stadium and James Bond's Aston Martin Db5. Should emphasise difference between length, area and volume scale factors.

Table for students to complete, identifying given expressions as lengths, volumes, areas or none of the above. Will print two to an A4 sheet.

<p>Worksheet in which students establish the measurements (scalar, length, area and volume) of James Bond’s car and the Olympic Stadium.</p>
