Spelling Counts!
Students count letters, tally, and
identify mode, median and range. 
During Review lessons we looked at words by position over the
5 lists in each section. Unit one, word one, Unit two, word one,
Unit three, word one and so on. This allowed us to look at the data
collected in more than one setting. (setting one in a group of 20;
setting 2 in a group of 5) Both settings have inherent difficulties
as the first is an even number, and the second a small sample).
This led to interesting discussions. =) 

Eventually, I hope to develop a card game for students
which will give them the mode, median, and range, and they will identify
the short list of words that match the characteristics!
Weekly 

1, Students write down the words in the spelling list and number
of letters in each word. 

2. As students write their wordlist they can set up the tally
area. As they encounter a new number add it to tally possibilities. 

First accuracy checkpoint. Does the number of tallies and the
number of spelling words match? Which number has the most marks?
That is the mode for
this list. In my example, words with 5 letters have the most datapoints
so, Mode = 5 



Using the tallies, prepare a least to greatest
list. If there are 3 tallies for 4 letter words, 5 tallies for 5
letter words, 3 for 6 letter words, 2 eight letter words. Your list
would look like the one below. 

4, 4, 4, 5, 5, 5, 5, 5, 6, 6, 6, 8. 8 Begin crossing
the numbers off each end of the list. The number in
the middle of the list is 5. So 

5 is the median
of this set of numbers. The greatest number of letters is 8. The
least number of letters is 4. To find the range
subtract the 

the 4 from 8. The range
of this set of numbers is 4. 



Review Lesson: Look at the data collected in
a different way. (By word position across several Units)
