Question

Female giraffes reach a height of 4.3 meters, and males reach a height of 5.5 meters. Kendra created a bar diagram and wrote an equation to find the difference in the heights.

A bar diagram. The top bar contains 4.3 meters and the bottom bars contain d and 5.5 meters.

d - 5.5 = 4.3

Write about the errors made by Kendra.

Answer 1

so she wants to find the difference in height between the male and female giraffes. meaning, she should set the equation in terms of d
ex: (d = ______)
where the difference in heights goes into the blank (larger height - shorter height)

the way she has it set up, she's implying that the d is 5.5 m larger than 4.3, which is not representative of the situation
