Room 4 Bake sale

December 12, 2009

 Hello Parents,

We are working towards having a guest teacher come in for two days to teach self portraits. In order to do this, we are selling cookies this Wednesday during lunch. We need two-three parent volunteers to come in at 8:15 to help us bake. If you are able to help, please email me.

Thanks!

Ms. Heather

P.S. Great stocking stuffer ideas for your kids are pencils, hand-held sharpeners and erasers!

P.S.S Please contribute to the Annual Campaign if you have not done so already. Every little bit counts, so do what you can. It would be great if Room 4 had 100% participation!

Current Happenings

November 09, 2009

Hello Parents,

We recently finished a social studies unit relating to California's geography. We culminated in a block building activity where the students mapped California.  You can see by the pictures what a fantastic job they did! Here are a few things we studied: major regions, largest desert, and mountain range, major industries and bordering states. Please ask your child these questions so that they may share their knowledge.

We have begun a science unit on ecosystems and interdependence. Look for opportunities to point out examples in your every day lives. We would love for students to share something they learned at home with the rest of the class.

As part of this unit of study, we are going to take a walking field trip to the Arroyo Seco. I will email the date as soon as possible. We will need plenty of volunteers!

Lastly, it would be helpful if you could supply your child with a large eraser. We seem to go through them rather quickly!

Warmly,

Ms. Heather

Parent Volunteers

October 08, 2009

    Many of you have so graciously offerred your help in the classroom. I can see where our immediate needs are and would like to share them with you in hopes that you may help.

1. Labeling our room library by reading level with color coded stickers (provided). We need to type the book names onto the scholastic site, and they provided that information. This is a big job, and all of the help I can get would be appreciated. Volunteer for one hour, or three. One day, or several.

2. Labeling our books by subject. Maintaining their order on our book shelves.

The best times to do this is either Monday or Friday mornings from 7:45-9:00. Or Tuesday-Thursday from 2:30-4:00.

If these times aren't possible, but you are interested in helping out another time, please email me. I'm sure we can work something out.

Thank you,

Heather Ashton

What I did this summer...

September 01, 2009

For a teacher, the summer is a time to get all of the things done we don’t get to during the school year, like the dentist. Ugh! It’s also a time to prepare for the following year and of course, relax! This summer I did just that. I caught up on all of the things I needed to, prepared my new classroom, read, and had some fun too.

I went to Santa Barbara for a week for a math conference. I learned a lot, and had the best ice cream in the world. It’s called McConnell’s and I would love to eat it everyday!

I also read a few books, one in particular we’ll be reading as a class. I won’t tell you what it is though because I want it to be a surprise.

Perhaps the most fun I had were the times I went to the Hollywood Bowl. I love to see concerts there. We brought a picnic and even saw fireworks.

Now, I think our classroom is ready, we’ll add fun things to it as we go. The main ingredient that’s missing is all of you.

Heather
