The student has

no idea of how to

determine the solution

or just says

1

3

hour by

dividing 300 by 3.

The student estimates

that it would take about

10 minutes to plant the

100 trees by assuming

the rate for Mia is

similar to the rate

for Kyla.

The student calculates

that it would take about

10.5 minutes to plant

the 100 trees.

The student can explain

how he/she determined

the solution.

The student figures

out that Kyla is faster

than Mia, but it was not

obvious to him/her.

The student uses an

alternate description

of one or both of the

given rates to solve the

problem.

The student calculates

that it would take about

10.5 minutes to plant

the 100 trees.

The student can clearly

explain how he/she

determined the solution.

The student can easily

explain why Kyla is

faster than Mia, but not

a lot faster.

The student can clearly

explain why different

descriptions of one or

both of the given rates

were useful for solving

the problem.
