FISHY PRICES

• Why can’t you figure out Arty’s cost before find-

ing Bronco’s cost? (The first fact states that Arty is

$1 less than Bronco, so we have to figure out Bronco’s

cost before we can find out Arty’s cost.)

Work together as a class to answer the questions

in “Solve the Problem: Fishy Prices.”

Math Chat With the Transparency

Display the “Make the Case: Fishy Prices” trans-

parency on the overhead. Before children can

decide which character is “wearing smarty pants,”

they need to figure out the answer to the prob-

lem. Encourage children to work in pairs to solve

the problem. Then bring the class together for

another whole-class discussion. Ask:

• Who has the right answer? (Carl Cargo)


• What do you think Carl Cargo did first to solve

the problem? (He matched the greatest cost with the

fish that costs the most. Ringo costs $7.)

• What did Carl do next? (He found Dolly’s cost

next. Dolly costs $5 less than Ringo; 7 – 5 = 2, or

$2.)

• How did Carl find PB and J’s cost? (PB and J cost

$3 more than Dolly; 2 + 3 = 5, or $5.)

• How do you think Shorty Trunks got his

answer? (He probably thought the number in the first

clue was PB and J’s cost.)

• How do you think Levi Sam got his answer?

(He might have thought that the words more than

in the first clue meant that PB and J’s cost must be

the greatest number.)
