[] =US12323 Version 3 Apply mathematics in the design of an object or process for a given purpose=
 * Students are to choose the mathematics needed.
 * Students must use mathematics from levels 6 and 7 of MINZC in the design.
 * Shapes must be more complex than a cuboid or cylinder.
 * The mathematical processes involved are expected to be above NCEA level 1.

[] =Measurement, Level 6=
 * AO1: Measure at a level of precision appropriate to the task.**
 * AO2: Apply the relationships between units in the metric system, including the units for measuring different attributes and derived measures.**
 * AO3: Calculate volumes, including prisms, pyramids, cones, and spheres, using formulae.**

[] =Shape, Level 6=
 * AO3: Use trigonometric ratios and Pythagoras’ theorem in two and three dimensions.**

[] =Number and Algebra, Level 6= [] For information about level 7. ---
 * AO4: Find optimal solutions, using numerical approaches.**


 * Tuesday 25th October 2011: Volume of triangular prisms.**
 * Design and make a triangular prism with a volume of 250cm^3.**


 * Wednesday 26th October 2011: Volume of triangular prisms.**
 * Design and make a triangular prism with a volume of 400cm^3.**
 * It must be no longer than 15cm, and no wider than 10cm.**
 * Show all your calculations, in a logical format.**
 * Show the net with all measurements.**
 * Calculate the volume, showing working clearly, to prove your prism is the correct volume.**
 * Can you make another one, that is different, but also fits the given dimensions.**
