Ms. Simeone is working with her first-grade students on writing two-
digit numerals. She wants to use an activity to assess whether her
students are attending to the left-to-right directionality of the
number system.
Which of the following activities is best aligned with Ms. Simeone's
purpose?
,Answer the question by selecting the correct response.
A. Asking students to read the numbers 20 through 29
B. Asking students to represent the numbers 35 and 53 using base-10
blocks
C. Asking students how many tens and how many ones are in the number
33
D. Showing students 23 cubes and 32 cubes and asking them which
quantity is greater
B
Option (B) is correct. Having the students represent 35 and 53 using
base-10 blocks will help Ms. Simeone assess whether students know
which place is the tens place and which place is the ones place or
whether students have reversed the ones place and the tens place,
thinking that the ones place is on the left and the tens place is on
the right. Representing the numbers provides more information about
students' understanding of place value than just reading numbers does.
