Dylan and Brianna each placed a 6 in their numbers. Once the 6 was placed in each
number, Dylan’s 6 was worth ten times as much as the 6 in Brianna’s number. Show
where Dylan and Brianna might have placed the 6 in their numbers.

Teacher notes:
• Students may do calculations on the paper, either to solve or to check their work. You may also
choose to give students extra paper on which they can do their work.
• Part of this task requires students to identify more than one possible answer among a set of
choices. Students should be aware that the phrasing “…all that apply” indicates that there may be
more than one correct answer to select and that they should identify all the correct answers.
• The target concept of this task is described in 4.NBT.1: Recognize that in a multi-digit whole
number, a digit in one place represents ten times what it represents in the place to its right. For
example, recognize that 700 &divide; 70 = 10 by applying concepts of place value and division.
• For this first part of this task, students place a check next to 4 and 5 but not 8.
• For the second part, the student should give an explanation that shows an understanding that
the 5 in Brianna’s number is worth 500,000 and the 9 in Dyaln’s number is worth 50,000, and
500,000 is ten times the size of 50,000 or that the 4 in Brianna’s number is worth 40,000 and that
Dylan’s 4 is worth 4,000, and 40,000 is worth ten times as much as 4,000 or that the 8 in Briann’s
number is worth 80 and Dylan’s 8 is worth 800 and that 80 is not ten times the size of 800. The
explanation does not have to address all of those digits and values, but should simply show an
understanding of place value relationships. The level of specifics in the answer may help
distinguish between a 3 and a 2.
• For the last part, there is only one place for the 6 to be placed. It must be placed in the ones
place in Brianna’s number and the tens place in Dylan’s numbers.
• When scoring this task, you may choose to use the level of student work to distinguish between a
3 and a 2 or a 2 and a 1. If you decide to account for the student’s work when grading, it is
important to make sure the students know in advance of working that the task will be graded
based on the correct answers and their work.
