Like all of the Problem Solving units, this one aims to introduce students to the underlying ideas of mathematics through a problem. The problem here requires a knowledge of arithmetic and the use of some algebra. In this unit we see how a mathematical theory might develop through experimentation, conjecturing, proving, generalising and extending. Full Review »

Students construct a variety of right triangles using a right-angled set square, cutting corners from pieces of paper or cardboard, and using dynamic geometry software. They measure the sides of these various right triangles and record measurements in a spreadsheet. Students use the spreadsheet to look for possible patterns in the measurements. They also use the spreadsheet to square the values of each measurement and to look for possible relations among squared values. Full Review »

Students form opinions about the role that technology plays in their everyday lives. They create a hypotheses about the effects of technology on the speed and accuracy of mathematical calculations and test that hypothesis with an in-class experiment. Students write lab reports that describe the experiment performed, analyze the results, and draw conclusions. Full Review »
