Complex numbers - exponential trig polar forms Tarsia jigsaw

Engage your students with this Tarsia jigsaw puzzle while they learn to recognise different forms of a complex number. Suited to groups of two or three or use them individually.
Skills included:
• Conversion of complex numbers from one form to another.
• The need for radians in exponential form.
• Degree and radian conversions using pi.
• Values of sine and cosine of 0, 90, 180 and 360.

Students do lots of thinking and learning. Small groups work really well as there is the shared goal of completing the puzzle. All students contribute as they all work at the same time and at their own pace on the same or different pieces. The activity also encourages maths talk.
I recommend you print the output onto card, then file and store for future use. It is useful to store a printout of the answers with the cards so you can easily see the topics covered. But you can also print them on paper and ask students to cut them up.

Formats included:
• Tarsia file for use with the free Formulator Tarsia programme (http://www.mmlsoft.com/)
• pdf files for those without access to the free programme.
• Answers included in both formats, although the activity is self-marking.
• Both i and j versions.
