Teacher's field guide

What Students Need to Do: Students read bar graphs, picture graphs, and simple tables about prices or items sold. They use labels and keys to find amounts and compare them.
What Mastery Looks Like: A student can read a snack sales graph and say how many of each snack sold. They can tell which sold more, by how many, and whether a number means items or dollars.
Common Misconceptions: Students may count each picture as one item without checking the key. They may also mix up an item's price with the number sold.
How to Assess It: Draw a picture graph with three apple symbols and two pear symbols, where each symbol means two sales. Ask, 'How many apples and pears sold, and how many more apples sold?'

Lesson moves

Give pairs counters and a pretend shop sheet showing 6 apples, 4 pears, and 2 bananas sold, then have them build a bar graph.
Show a graph with 6 apples and 4 pears sold, then ask, 'How do you know apples sold two more?'
Play graph detective: partners draw question cards about the most sold or how many more, then point to the graph for proof.
Use two prices from a grocery flyer to make a price chart, then ask which item costs more and by how much.
