What This Standard Means
What Students Need to Do
- Students explain how a price change affects how much buyers purchase and sellers offer. They show how weather, income, or production costs can change demand or supply.
What Mastery Looks Like
- At a higher lemonade price, a student shows fewer cups bought and more cups offered along the curves. They shift demand right for a heat wave and supply left for higher sugar costs.
Common Misconceptions
- Students may say a higher lemonade price shifts demand, rather than moving buyers along the demand curve. They may put higher sugar costs on the demand curve, even though those costs affect supply.
How to Assess It
- Exit ticket: Treat these separately: lemonade's price rises, a heat wave hits, and sugar costs rise. On one graph, mark price movements on both curves and the direction of each shift.
Lesson moves
Ways to Teach It
Give pairs graph paper and sticky notes to move along lemonade curves after a price change, then shift curves for heat and higher costs.
Ask: A heat wave brings more lemonade customers, but lemonade costs $1 more. Which change shifts demand, and which moves along it?
Label four corners: demand move, supply move, demand shift, supply shift; read cards on buyer prices, seller prices, heat, and sugar costs.
Compare an egg sale flyer with a bird flu headline; sketch the price effect on buyers and the production effect on sellers.
