1. 1. A kindergarten teacher observes
as a small group of students practice
compar- ing numbers and quantities
using manipu- latives. Each student
has four counters. One student's
2.
counters are spaced farther apart
than the other students' counters, and
sever- al members of the group claim
that student has more counters than
everyone else. The teacher can build
on the students' under- standing of
counting and cardinality by:
A. encouraging the one student to
count their counters for the
group.
B. identifying the error and moving
the one student's counters closer
together.
C. asking probing questions about the
total number of counters each
student has.
D. prompting the group to combine
their counters and count how many
they have in all.

A. Having one student count their own set of counters aloud
does not address the misconception that the number of coun-
ters in a set depends on how they are arranged.
B. This manner of addressing the mis- conception does
not necessarily build upon the students' understanding be-
cause the teacher did not check whether they grasped the
explanation or provide them with opportunities to explain in
their own words why the total number of objects in each group is
the same.
C. CORRECT. By asking probing ques- tions about the total
number of counters each student has, the teacher can help
students move beyond a naïve concep- tion that bigger equals
more and deepen their conceptual understanding of count- ing
and cardinality.
D. The attordances created by combining the counters into
a large group do not otter these students more substantive in-
sights into understanding counting and cardinality concepts
than the attordances created by using smaller groups of coun-
ters.
