Classroom Procedures


It's best to eat a healthy breakfast at home, but if your child eats breakfast at school, please encourage them to get their breakfast and report directly to homeroom.   This will keep missed class time to a minimal amount. We do important activities in the morning, so it is best that they miss as little of this time as possible.


Please ONLY bring snacks on the approved list. (Perhaps keep in on your refrigerator)

Eat your snack neatly and please clean up after yourself.


Students may get a drink anytime the teacher is not directly instructing.

Hydration Station: I have allowed water bottles at desks in the past and have found that they are a distraction, take up room on the desks, become toys, get the desks wet from sweating, and frequently spill. This year, we are going to keep our water bottles at a designated spot called the hydration station. Because of this, please make sure all water bottles are labeled with your child's name.  A reusable water bottle is best.  Thank you!  


Students use the bathroom signal and try to avoid asking during direct instruction. One boy and one girl may go at a time. 


Please make every effort to make sure your child comes to school. You wouldn't believe the amount of learning they miss when they are gone! If your child is absent, please send an excuse note on the day they return, or better yet, email it the day they are out! You can email to to the office and also cc me at . If you would like missed work for your child, please email the morning of his/her absence and tell me who to send it home with. I'll do my best!

We use Everyday Math as our math program. This is great because there is an online component! The students and parents have access to the textbook, homework pages, tutorials, and games. Students will have a math journal which is where we do our classwork. They will have a Home Links book which is where their homework sheets are. Each day that we have math, your child will rip out a Home Links page and put it in their homework folder. Both workbooks usually stay at school so they don't get lost or forgotten.

Unit 1 Place value ; Multi-digit Addition and Subtraction
Unit 2 Multiplication and Geometry
Unit 3 Fractions and Decimals
Unit 4 Multi-digit Multiplication
Unit 5 Fraction and Mixed Number Computation; Measurement

Hello! I am happy to be your teacher! Let me tell you a little about myself.

I have been teaching at Upper Perk since the year 2000. I taught the gifted program for one year, but otherwise have spent all of my time teaching first fifth and then fourth grade. Before I became teacher, I was a social worker. I received my teaching degree and my Master's Degree from West Chester University.

I live with my husband, son, and granddaughter. We live in a town called Stowe which is about 30 minutes from school. I also have a step-daughter named Paige who is a nurse. My granddaughter's name is Isabella, and she is five years old. I also have an 2 year old old grandson named Turner. I love spending time with them both!
I like to travel, listen to music (especially country), go out to dinner, dance, and go to yard sales and flea markets. I love plants and animals! In the spring and summer I can be found out in my gardens during my free time. I grow all types of flowers, but some of my favorites are poppies, cone flowers, peonies, and hydrangeas. I have a lot of house plants too! I enjoy taking care of them when I can't be outside in my gardens. My biggest hobby is photography! I love taking and editing photos!


A few favorites:

Favorite subject to teach--math

Favorite book series--The Hunger Games

Favorite Children's Movie--Matilda

Favorite Children's book--Because of Winn-Dixie

Favorite place I've been--Italy!!

Favorite food--pizza!

Dear Parents-

As we are all very much aware, technology is ever evolving and has afforded teachers many new opportunities to keep parents and students connected to their classroom. In an effort to give families the opportunity to see what goes on inside our classroom during the school day, I have created a PRIVATE Instagram account for our fourth grade class. As the teacher, I am responsible for approving anyone that would like to follow our page and only those with approval will be able to see any of the pictures or posts.

If you are not familiar with Instagram, it is a free online photo-sharing and social networking service that enables users to take and share pictures (of both people and items/objects). Instagram is available as both a smart phone app or can be accessed through the website You will need to create an account if you do not already have one.

The following are some examples of things I hope to share on our Instagram page: student work, pictures of students engaged in various activities, pictures of classroom parties/special occasions, pictures of assemblies, field trips, brain teasers/puzzles, etc. Additionally, I also hope to allow the students to share items they are proud of on the page. Positive comments from parents and students are also encouraged underneath our class posts! (I will be actively monitoring this site and any negative or inappropriate remarks will result in a loss of access to our class page)

If you would like to follow our page, please search for the user name “mrsdiff16”. As previously mentioned, I will need to approve your request before you are able to view any of our posts. Please note, I respect all parents’ individual decisions when it comes to social media and their children’s participation. Following our class page is completely voluntary and additionally, having your child appear on our page is entirely up to you! Please fill out the permission slip below indicating your preferences.

Thank you so much! Please don’t hesitate to contact me with any questions or concerns. J

Kim Diffenderfer (

Dear Parents,

My goal for the year is to try to keep you as informed as possible about the happenings in our 4th grade classroom. Knowing that many of us use our cell phones, specifically texting, to communicate, I have become very fond of the program “Remind 101.” This is the fourth year I will be using it in my classroom and it is the #1 thing parents have requested that I continue!

Remind 101 is incredibly simple to use and will allow me to send you information regarding our classroom directly to your cell phone via a text message. Signing up is easy and free. I will be using this service to text out reminders about upcoming tests/quizzes, large homework assignments, various school activities, etc.

Remind 101 is a one sided conversation. I am able to send out a mass text message to you, however you are not able to reply to me so if you would have any questions regarding something that was texted to you, you would need to e-mail that question to my standard e-mail address and wait for a reply.

This program is completely voluntary, and your standard text messaging rates would apply.

To subscribe to my updates, please follow the two simple directions below!

1. Enter this number as the recipient of a new text message: 81010 This is the number you will be texting.

2. Text this message to the above number: @diffend4

You should receive an automatic reply back welcoming you to my class. If you have never used the program before, it will then ask you to reply with your full name. PLEASE USE YOUR FIRST AND LAST NAME.

You will then be signed up for all future text messages. If at any time you would like to unsubscribe to my text updates, text “HELP” and it will give you instructions to stop the messages.

Thank you for your continued support. I hope you find this service helpful in keeping up with our classroom!
