The student finds only

one or two sets of

numbers and does

not address impossible

numbers.

The student’s strategy

appears somewhat

random with no clear

indication that he/she

sees any patterns or

relationships.

The student does not

make a prediction

about 60 objects or

predicts incorrectly.

The student finds

only a few possible

sets of numbers. The

student does not find

impossible numbers

greater than 3.

The student’s strategy

appears somewhat

random with no clear

indication that he/she

sees any patterns or

relationships.

The student does not

make a prediction

about 60 objects or

predicts incorrectly.

The student determines

at least four different

possible numbers and

at least two or three

impossible numbers,

including at least one

beyond 3.

The student shows an

approach that would

allow him/her to get

further answers if

requested.

The student may or

may not predict that

60 objects is possible.

The student determines

that all the numbers

that are 3 apart

starting at 3 (i.e., 3, 6,

9, 12, 15, …) are possible

and no other numbers

are possible.

The student explains

why a number 3 greater

than any answer that

works also has to work

or recognises in some

other way why there is

a neverending set of

possibilities.

The student predicts

that 60 objects is

possible and gives a

clear reason as to why.
