We know that the foundation of mathematics is number sense. Therefore, our goal at DC-G is to ensure that your child has a strong conceptual understanding of numbers.
How do we develop number sense?
The foundation of number sense is subitizing. Subitizing means instantly seeing how many. It is from a Latin word meaning suddenly. Subitizing is somewhat of an innate ability that needs to be nurtured and practiced in order to improve. In the classroom, we show students a card with random dots on the card. This card is only held up for about one second and then it is taken down. Students are then asked to tell how many dots they saw and to explain what they saw.
What can I do at home to help?
You can find links to subitizing activities below. You can also find links to subitizing activities below. However, any dice games, dominoes or playing cards can help solidify this ability. You can subitize anywhere

How do we develop understanding?
One way in which we develop true conceptual knowledge of skills and content is by teaching using the CRA model. The CRA model is explained below.
Concrete: students demonstrate understanding through the use of concrete materials or objects (manipulatives).
Representational: students demonstrate understanding by drawing or using pictures.
Abstract: students demonstrate understanding by using the written symbol that represents math constructs (numbers, operation signs, variables).
What can I do at home to help?
One simple thing you can do at home, when your child is working on math, is to ask them one or more of the following questions:
· Can you please explain your thinking to me?
· How did you reach that conclusion?
· Does your answer make sense? Why does it make sense?
· Can you make a model or draw a picture to show your thinking?

North Ridge Facts
North Ridge is one of three elementary schools in the Dallas Center-Grimes School district. We are located at 400 NW 27th on the north side of Grimes, Iowa. Our school is a two-grade level building, teaching third and fourth grade students from the Grimes area. We have approximately 250 students.
North Ridge operates with a self-contained classroom concept. Each student's assigned teacher teaches all curriculum areas, with students changing teachers and classrooms for Art, Music, Physical Education, Library and Guidance.
Teachers and students are supported in their efforts by a principal, an office administrative assistant, instructional associates, custodians and our lunchroom staff.
We have excellent teachers and support staff who are committed to providing a safe and respectful learning environment. Our school values the wonderful support of our families, the dedication of our volunteers, and the resources provided by our community. We are very proud to be a part of the Dallas Center-Grimes Community School District.
The North Ridge School Building has much to offer its students. We have an exceptional new facility with the state of art learning space available for our students and staff. The building opened in the fall of 2008, facilities include a media center with computer lab, art studio, music room, a full-sized gymnasium, a separate lunchroom, and over 14 classrooms.
North Ridge students can ride buses to school by boarding route bus stops located throughout the town of Grimes. The students will ride the same bus home and be dropped at the neighborhood bus stops. Please access the DC-G transportation web pages to find the nearest bus stop.
