Rm. 21 Update

Dear Families,

 I hope that your winter break was relaxing and that you are enjoying the break in the rainy weather. The commute to Lexington was pretty exciting last week- I think I now know just about every possible land route from Santa Cruz to Lexington!

 I would like to say thank you to our Room Parent, Candice Pacheco, for putting together a fabulous holiday party. The activities were outstanding and the kids really had a good time. (I hope that there were no gastronomical repercussions from the quite impressive cookies the kids created. They were truly magnificent!) I would also like to say thank you for the kind wishes and thoughtful gifts. My family and I are still enjoying many of them.

 Here’s what’s happening in Rm. 21


In reading we will be focusing on informational text. Goals for this standard include:

-Ask and answer questions to demonstrate understanding of a text, referring explicitly to the text as the basis for the answers.

-Determine the main idea of a text; recount the key details and explain how they support the main idea.

-Describe the relationship between a series of historical events, ideas or concepts, or steps in a process using language that pertains to time, sequence, and cause/effect.

-Use text features and search tools to locate information relevant to a given topic efficiently.

-Distinguish their own point of view from that of the author of a text.


In writing we will be focusing on writing informative explanatory text. Goals for this standard include:

-Introduce a topic and group related information together.

-Develop the topic with facts, definitions, and details.

-Use linking words and phrases to connect ideas within categories of information.


In mathematics we will continue our work with multiplication and begin work with division. Goals include:

-Know from memory all products of two one-digit numbers.

-Multiply and divide within 100, using strategies such as the relationship between multiplication and division (fact families!)

-Use arrays to interpret products

-Interpret whole number quotients of whole numbers, e.g., interpret 56/8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares.

-Use multiplication and division within 100 to solve word problems.


Our new IB unit is, Where We Are In Space and Time. The unit is an inquiry into orientation in place and time; personal histories; homes and journeys; the discoveries, explorations and migrations of humankind; the relationships between and the interconnectedness of individuals and civilizations, from local and global perspectives. Lines of inquiry for the unit include:


  • The lifestyle of indigenous people (Form)
  • Comparing indigenous cultures (Connection)
  • The results of interaction between indigenous and        non-indigenous people (perspective)

 We will be making a study trip to Sanborn Park on February 6th for this unit. Please be on the look out for permissions slips.

That’s all for now!

Room 21 Update

Dear Families,

 Scribble Robot Kits have arrived and room twenty-one is ready for launch! We will be building robots this Friday. Thank you to those who have sent in materials for construction, but we are still in need of stuff. Yogurt containers, strawberry baskets, popsicle sticks, light weight cardboard, masking tape (we will need lots of this), straws. Think lightweight and easy to manipulate. To see some scribble robots in action go to: http://tinkering.exploratorium.edu/scribbling-machines

 Our first field trip is scheduled for November 8th. We will be going to Montalvo Arts Center to see a performance by San Jose Taiko. This study trip pairs very nicely with our current unit, How we Express Ourselves. Mrs. Fountain’s class will also be attending and we will enjoy a picnic lunch on the grounds after the event. Look for permission slips in your child’s red homework folder. If you are interested in chaperoning, please indicate so on the permission slip.

 Parent conferences will be held the week of November 14th. We will be on a minimum day schedule for the entire week in order to accommodate conferences. You will receive an email from me with a link to sign up for your conference.

 Thanks, and I look forward to seeing you!

Mr. Keuter











Rm. 21 Update

Dear Families,
Reaching out to you tonight to let you know that if you are still interested in participating in Lexington's Multicultural Festival on the 21st, it isn't too late. Follow the link above for more details.
I am also writing to request a donation of $5.00 to purchase a "Scribbling Starter Pack" for your son or daughter. This is a project that I came across with my family recently on a trip to the Exploratorium in S.F.. The kits include a small hobby motor, AA battery, markers, necessary wiring, and a few other odds and ends that will enable students to put together their own machine. The machines  provide a playful and inventive way for the children to explore variables and the process of trial and error. It was my thought that building and experimenting with the machines would be a great way to kick of science exploration in Rm. 21. Please see the link below for more info.http://tinkering.exploratorium.edu/scribbling-machines

Rm. 21 Update

Dear Families,

 It was wonderful to see you all at Back to School Night. If there is anything that I did not cover that you are still wondering about, please feel free to contact me.

 Here is a brief overview of concepts and skills that we will be working with over the next several weeks:

 IB Unit: “How We Organize Ourselves.”

 This unit deals with the concepts of rights, responsibilities, and how groups organize themselves. We will be looking at the three branches of the federal government and the differences between federal, state, and local government.


 Reading- Guided reading with Mr. Keuter from social studies text and selected sources on the three branches of government and rights and responsibilities.T-chart notes will be introduced.

 Skills practiced:

 Read closely to determine what the text says explicitly and to make logical inferences from it; cite specific textual evidence when writing or speaking to support conclusions drawn from the text.

 Determine central ideas or themes of a text and analyze their development; summarize the key supporting details and ideas.

 Analyze how and why individuals, events, and ideas develop and interact over the course of a text.



Use place value understanding and properties of operations to perform multi-digit arithmetic.

  1. Use place value understanding to round whole numbers to the nearest 10 or 100.
  2. Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.


Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.

  1. Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.



Write narratives to develop real or imagined experiences or events using effective technique, well-chosen details, and well-structured event sequences.

  1. Write narratives to develop real or imagined experiences or events using effective technique, descriptive details, and clear event sequences.
    3a. Establish a situation and introduce a narrator and/or characters; organize an event sequence that unfolds naturally.

3b. Use dialogue and descriptions of actions, thoughts, and feelings to develop experiences and events or show the response of characters to situations.

3c. Use temporal words and phrases to signal event order.

3d. Provide a sense of closure.


Produce clear and coherent writing in which the development, organization, and style are appropriate to task, purpose, and audience.

With guidance and support from adults, produce writing in which the development and organization are appropriate to task and purpose. (Grade-specific expectations for writing types are defined in standards 1–3 above.)



 We have a need right away for a Library Parent. Our Library time is on Tuesday from 10:30-11:15. If you can fill this spot, please let me know a.s.a.p.

 I am still assessing the kids and introducing them to our academic routines. As we settle in, I will begin to contact those who were interested in volunteering.
