The Spache Readability Formula is designed to categorize reading materials for grades 1-3. For a passage of text, the variables are S, the number of sentences, W, the number of words, and U, the number of unfamiliar words (words not on a specific list). The formula (as revised) for the grade level is

In this exercise we consider passages having 270 words and using 8 unfamiliar words.

1. What is the maximum possible number of sentences?
Sep 25th, 2015

the possible grade is in between 1 and 3

=0.121*270/S + 0.082*8 +0.659

= 32.67 /S + 1.315

grade level - 1.315 = 32.67 /S

S = 32.67 /  (grade level - 1.315)

so number of sentence will be maximum when grade level is 1

S = 32.67 / 1 - 1.315

= 32.67 / 0.315

= 103.714

since it is number of words it is rounded to 103

so maximum possible number of sentences = 103

hope you understood..please message if you have any doubts...thank you
