Activity 01
Graphing Pairs: Income Shifts
Pairs sketch a demand curve for a normal good like laptops. One partner announces an income rise; the other redraws the shifted curve and predicts quantity changes. Pairs then explain their graphs to the class.
Predict how a change in consumer income affects the demand for normal goods.
Facilitation TipDuring Graphing Pairs, give each pair two different colored pens to plot the original curve and the shifted curve, making visual contrast immediate and reducing confusion between movement and shift.
What to look forPresent students with scenarios: 'Consumer income has risen by 10%.' 'The price of coffee has fallen.' Ask them to identify if this causes a movement along or a shift of the demand curve for tea, and to state the reason why.
