Helping students become effective communicators

Communication 3

Elementary Connections:

At OCSI we want your children to become effective communicators, including being effective writers. Through the Writer’s Workshop program, your child is encouraged to write on a variety of topics and in a variety of genres. Writing can help your child discover new things, reflect on their experiences, and teach others a new skill or idea. Here are some of the ways the teachers here at OCSI are helping your children become better writers:

Communication 2

“In Pre-K, students draw and write in notebooks. They are practicing their pre-writing skills. Parents can help at home by providing time with playdough to strengthen fine motor skills to prepare for future writing activities. In PreK we start helping our children the proper way of holding the pencil. Figuring out if the student is left or right handed.
We do appreciate parents’ support at home. In your child’s free time please give them a crayon or pencil and a paper to write, draw etc. It is also great if you as parent could spend time with your child. Make it a fun or game type of writing or drawing with your child. Not just giving your child a crayon and a paper.” — Mrs. Pallmann

“In Kindergarten, many of my students like to draw pictures, and I always encourage them to write something about their pictures. Most of them can tell what they drew but are hesitant to write. So, we start by just labeling their pictures and hoping they will become comfortable writing something about their pictures soon. Parents at home can integrate technology and mobile devices to motivate their students to write. Perhaps do a selfie adventure with their students and then use the pictures to encourage them to write something about their adventure. They can also take selfies of their favorite books, pets, or places they have been. With helpful prompts, I believe students will have fun writing!” — Mrs. Ikehara

“In 1st grade we have just completed our ‘how to’ writing unit! We have learned all about how to use “time” words and tell things in sequential order. We are moving into a short letter writing unit and will even be writing to first graders in Singapore! Parents may want to help their children by writing notes or letters to their child at home. They may also want to help their children write to someone who lives far away and go to the post office together to mail the letter!” — Mrs. Fox

“In 5th grade we become better writers by becoming better readers and then by writing what we read about. This quarter we read biographies and the students created posters and gave presentations on their findings. This was great for understanding informational texts and looking at historical figures through the different lenses of the authors the students read.” — Mr. Doerksen

Welcome back from Christmas vacation 


PTF Connections:

We hope everyone had an amazing break and enjoyed spending time with their families and relaxing. We are pleased to announce the kids hoodies have arrived and the kids love them. We have already sold over seventy percent of our stock, exceeding our expectations. We are grateful for the support of the OCSI families, and we hope everyone enjoys the design and style as much as we do.


On January 14th, 2019, during the classroom observation and kite day, the PTF will be selling our OCSI adult sweatshirts and kid hoodies at the sale price. This special price ends soon, and there is a limited quantity, especially in the kids’ colors and sizes. We plan on submitting an additional order for the kids hoodies. However, we will need parents to submit an order form and payment to ensure the desired color and size as we are not ordering any stock beyond that. This order will be placed next week so please submit all orders as soon as possible as this is the final opportunity to do so.

In addition, please check in with the office for classroom observation day on the 14th of January. Each class has its own time schedule for this event so please ask for your respective grades. It will be a busy day as both secondary and elementary parents will be on campus for this event—so please plan accordingly. We look forward to seeing all our elementary families cooperating together to get their kites in the sky and enjoying the opportunity to observe the secondary and elementary classrooms to see the students’ learning environments.

On January 24th, 2019, from 2:00PM to 3:00PM, the PTF will be hosting its second general meeting. This meeting will review our recent events, provide information about upcoming events, and allow us an opportunity to discuss feedback from these topics for future planning. We also plan to have coffee and snacks so we can have time to relax and meet and greet each other at the beginning of the meeting. We hope everyone can attend and enjoy themselves. If you have any questions, suggestions, comments, or concerns, please email us at ptf@ocsi.org. Please continue to check our Facebook, LINE, or the OCSI website for updates.
