Pick Up Sticks!


My students are now half way through the chapter on fractions.  They seem confident in performing the different operations, but a few are still unsure of how to reduce fractions. 

Although I have stressed learning the Divisibility Rules for 2, 5, 10, and the digital root for 3, 6, 9, (September 21st posting) some still have difficulty since they do not know their multiplication tables.  This week we made Pattern Sticks, a visual and kinesthetic aid, similar to a multiplication chart like the one on the left. Notice that an extra column (blue) has been added to the chart. (In this space, a hole is punched so that a 1" ring can be inserted to store all of the sticks in one place.) .

On the right are the directions for making the Pattern Sticks using a multiplication chart. 

(Side note:  My students cut out individual Pattern Sticks which I prefer over cutting a multiplication chart apart.  If you are intetested in these, see the link under the scary fingers.)
I then gave the students fractions such as 9/36 to reduce.  Using the Pattern Sticks, they looked for a column where a 9 and a 36 were lined up in the same one.  They easily found it on the 1 strip and the 4 strip.  They then took the two strips and lined up the two so that the 9 was over the 36.  (see illustration above)  By going to the left, they discovered that 9/36 is the same as 1/4.  This is 9/36 in its lowest terms. Also notice that all the fractions in the illustration above are equivalent fractions: fractions that have the same value.  We also used the Pattern Sticks to determine what number to divide by and to change improper fractions to mixed numbers.

On a more elementary level, the Pattern Stricks can be used to practice skip counting.   I purchase those scary, wearable fingers at Halloween time. (You can purchase them in bulk from the Oriental Trading Company.)  My students wear one for such activities as this.  I call them the Awesome Fingers of Math!  For some reason, when wearing the fingers, students tend to actually point and follow along when skip counting.  (If you like this idea, be sure that each student uses the same finger every time to avoid germs, etc.  Keeping it in a zip lock bag with the child’s name on the bag worked best for me. Believe it or not, when I taught middle school, the students would paint and decorate the fingernails!)

The ROOT of the Problem

When students skip count, they can easily say the 2's, 5's, and 10's which translates into easy memorization of those particular multiplication facts.  Think what would happen if every primary teacher had their students practice skip counting by 3's, 4's, 6's, 7's, 8's and 9's!  We would eradicate the drill and kill of memorizing multiplication and division facts.

Since many of my college students do not know their facts, I gravitate to the Divisibility Rules.  Sadly, most have never seen or heard of them.  I always begin with dividing by 2 since even numbers are understood by almost everyone.  (Never assume a student knows what an even number is as I once had a college student who thought that every digit of a number must be even for the entire number to be even.) We then proceed to the rules for 5 and 10 as most students can skip count by those two numbers. 

Finally, we learn about the digital root for 3, 6, and 9.  This is a new concept but quickly learned and understood by the majority of my students.  (See the definition below).




 Here are several examples of finding Digital Root:

1)   123 = 1 + 2 + 3 = 6.  Six is the digital root for the number 123.  Since 123 is an odd number, it is not divisible by 6.   However, it is still divisible by 3.

2)   132 = 1 + 3 + 2 = 6.  Six is the digital root for the number 132.  Since 132 is an even number, it is divisible by 6 and by 3.

3)   198 = 1+ 9 + 8 = 18 = 1 + 8 = 9.  Nine is the digital root for the number 198; so, 198 is divisible by 9 as well as by 3.

4)   201 = 2 + 0 + 1 = 3. Three is the digital root for the number 201; so, 201 is divisible by 3.
  

      The first time I learned about Digital Root was about six years ago at a workshop presented by Kim Sutton.  (If you have never been to one of her workshops - GO!  It is well worth your time.)  Anyway, I was beside myself to think I had never learned Digital Root.  Oh, the math classes I sat through, and the numbers I tried to divide by are too munerous to mention!  It actually gives me a mathematical headache.  And to think, not knowing Digital Root was the ROOT of my problem!

Meet the Parents!



In preparing for parent/teacher conferences, what can be done a daily basis?  Is the conference based on simply talking about grades or are there additional items that need discussing?  How can an observation be specific without offending the parent or guardian?  Is it possible to remember everything?

My student teachers were required to keep a clipboard on which were taped five 6” x 8” file cards so they overlapped - something like you see in the two pictures above.  Each week, they were to evaluate five students, writing at least two observations for each child on the cards.  At the end of the week, the cards were removed, and placed into the children's folders.  The next week, four different students were chosen to be evaluated.  In this way, the student teacher did not feel overwhelmed, and had time to really concentrate on a small group of children.  By the end of 4-5 weeks, each child in the class had been observed at least twice.  By the end of the year, every child had been observed at least eight different times.

Below are sample observations which might appear on the cards.

Likes to work alone; shy and withdrawn; wears a great deal of make-up.

She has a good self concept and is friendly.  Her preferred learning style is visual based on the modality survey.

2/21
Leader, at times domineering, likes to play games where money is involved.

His preferred learning style is auditory (from the modality survey).  He can be a “bully,” especially in competitive games.  He tends to use aggressive language with those who are not considered athletic.




Checklist for Parent/Teacher Conferences
By the time the first parent/teacher conferences rolled around, the student teacher had at least two observations for each child.  This allowed them to share specific things (besides grades) with the parents/guardians.  As the year progressed, more observations were added; so, that a parent/guardian as well as the student teacher could readily see progress in not only grades, but in behavior and social skills.  The cards were also an easy reference for filling out the paperwork for a 504 plan or an IEP (Individual Education Plan).  As a result of utilizing the cards, the student teachers learned pertinent and important facts related to the whole child which in turn created an effective and relevant parent/teacher conference.
