Ohio Assessments for Educators OAE Mathematics 2

Question 1

A rectangle has a perimeter of 36 cm and a length of 10 cm. What is the width?

Accepted Answer

8 cm

Answer

Using P = 2(l + w): 36 = 2(10 + w), so 18 = 10 + w, giving w = 8 cm.

Question 2

Which measure of central tendency is most affected by outliers?

Accepted Answer

Mean

Answer

The mean uses all data values in its calculation, so extreme outliers pull it significantly higher or lower.

Question 3

In the OAE content framework, proportional reasoning is primarily associated with which grade band?

Accepted Answer

6–8

Answer

Proportional reasoning is a cornerstone of the middle grades (6–8) mathematics curriculum in Ohio standards.

Question 4

A teacher wants to assess conceptual understanding of fractions. Which task best measures this?

Accepted Answer

Explain why 1/2 > 1/3 using a number line

Answer

Explaining reasoning using a number line demonstrates conceptual understanding of fraction magnitude rather than procedural skill alone.

Question 5

Which transformation preserves the size and shape of a figure?

Accepted Answer

Isometry (congruence transformation)

Answer

Isometries—translations, reflections, and rotations—preserve both size and shape, maintaining congruence.
