1. Rewrite each rate or price so that it uses the word "per"
a. The weather got warmer at a rate of 3 degrees Fahrenheit each day.
b. The train went 40 miles an hour
c. The chocolate costs $2 for a bar.
2. Rewrite each rate or price so that it uses the word "each"
a. The car was driving at 45 miles per hour.
b. The price was $1.50 per hot dog.
c. Green beans cost $3 a pound.
3. For each rate or price problem, decide if it is a multiplication, measurement division or partitive division problem.
a. The toy train takes 3 minutes to go 18 feet. How far will the train go in 1 minute?
b. Finger puppets cost $4. How many finger puppets can you buy with 20?
c. The bean plant grew 3 inches per day. How much did it grow in 7 days?
d. Kelly bought 6 packs of Pokemon cards for $24. How much did each pack of cards cost?
e. 2 ounces of water evaporates from the bucket each hour. How long will it take for 10 ounces of water to evaporate?
f. A toy dragon costs $6. How much do 4 dragons cost?
4. For each of these Cuisenaire rod problem solving strategies, decide if it's finding the solution to a multiplication, measurement division or partitive division problem.
a. Put out Cuisenaire rods to show the amount 32 (using 3 orange tens and 1 red 2), and then put purple (length four) rods next to them until the amounts are even. Finally, count how many purple rods there are to find the answer.
b. Put out Cuisenaire rods to show the amount 32 (using 3 orange tens and 1 red 2). Then put 4 yellows out next to them, notice that the amounts are not even. Put out 4 blacks, and notice that the amounts are not even. Put out 4 browns, and notice that the amounts are even. Figure out/remember how long a brown is.
c. First, put out 6 black (length 7) Cuisenaire rods, then figure out that the total length is 42.
5. True or false: Rate and Price problems should usually be solved with Cuisenaire rods.
