Workshop 6: Using charts

Refresh your memory

Previous workshop

Using drawing tools. Have you used drawing tools in new contexts? Do you have anything to share?

Experience

People are wise in proportion, not to their experience, but to their capacity for experience. * George Bernard Shaw

Activity 1: Linear graphs

Work in pairs. 30 min

Produce a linear graph to suit your own needs as a teacher.

Activity 2: Challenge – quadratic equations

Work in pairs. 45 min

Use any quadratic equation y = ax2 + bx + c Show in graphical format the effect of changing:

a - the coefficient of x2 c - the y intercept

Draw at least three graphs for each case.

Activity 3: Reflection and sharing

Work in large groups. 45 min

How can access to Microsoft Excel help you design a lesson for learners to generate the conclusions about the effect of changing the y intercept and the coefficient of x2 in any quadratic equation?

What other ideas do you have for using Excel in learning situations?

Between workshops

Experiment with graphs and mathematical expressions.

Explore the use of charts with learners, as discussed during the workshop.
