QuestionA student reads 140 words in 40 seconds and makes 20 errors. What is the ORF score of the student?

Studdy Solution

STEP 1

1. ORF stands for Oral Reading Fluency.
2. The ORF score is calculated as the number of words read correctly per minute.
3. The student reads 140 words in 40 seconds and makes 20 errors.

STEP 2

1. Calculate the number of words read correctly.
2. Convert the reading time from seconds to minutes.
3. Calculate the ORF score.

STEP 3

Calculate the number of words read correctly by subtracting the number of errors from the total number of words read:
$\text{Words read correctly} = 140 - 20 = 120$

STEP 4

Convert the reading time from seconds to minutes. Since there are 60 seconds in a minute:
$\text{Time in minutes} = \frac{40}{60} = \frac{2}{3}$

STEP 5

Calculate the ORF score by dividing the number of words read correctly by the time in minutes:
$\text{ORF score} = \frac{120}{\frac{2}{3}} = 120 \times \frac{3}{2} = 180$
The ORF score of the student is:
$\boxed{180}$

Studdy Solution

STEP 1

1. ORF stands for Oral Reading Fluency.2. The ORF score is calculated as the number of words read correctly per minute.3. The student reads 140 words in 40 seconds and makes 20 errors.

STEP 2

1. Calculate the number of words read correctly.2. Convert the reading time from seconds to minutes.3. Calculate the ORF score.

STEP 3

Calculate the number of words read correctly by subtracting the number of errors from the total number of words read:Words read correctly=140−20=120 \text{Words read correctly} = 140 - 20 = 120 Words read correctly=140−20=120

STEP 4

Convert the reading time from seconds to minutes. Since there are 60 seconds in a minute:Time in minutes=4060=23 \text{Time in minutes} = \frac{40}{60} = \frac{2}{3} Time in minutes=6040​=32​

STEP 5

Calculate the ORF score by dividing the number of words read correctly by the time in minutes:ORF score=12023=120×32=180 \text{ORF score} = \frac{120}{\frac{2}{3}} = 120 \times \frac{3}{2} = 180 ORF score=32​120​=120×23​=180 The ORF score of the student is:180 \boxed{180} 180​
