Mathematics Chapter 6<br />
Representing<br />
Representation is a means <strong>of</strong> communicating. Learners<br />
should be encouraged to represent their thinking by<br />
using clay, blocks, drawing, language, diagrams, charts<br />
and eventually number symbols. Merely writing number<br />
symbols should not be a primary focus. The experience<br />
<strong>of</strong> conveying thoughts becomes a tool for making<br />
relationships in mathematics. Children remember what<br />
they were thinking, rethink new possibilities and make<br />
connections to new and old ideas. Representation is<br />
an opportunity to revise and make thoughts clearer to<br />
ourselves and to others. To encourage development <strong>of</strong><br />
representation skills, teachers should use the following<br />
strategies:<br />
• encourage representation as a continuous<br />
journey rather than as discrete projects that<br />
are finished and never addressed again;<br />
• make learning an ongoing series <strong>of</strong><br />
investigations that are all connected and<br />
integrated by the learner; and<br />
• encourage children to visually and<br />
physically represent math ideas with blocks,<br />
manipulatives, in drawing and in many<br />
media forms.<br />
CONTENT STANDARDS<br />
This section presents broad concepts that should be<br />
included in a preschool mathematics curriculum. Each<br />
concept includes appropriate performance standards, a<br />
brief description <strong>of</strong> the topic area, skills to be cultivated,<br />
suggested teacher strategies, and ideas for maintaining<br />
a home-school connection.<br />
Number Sense And Operations<br />
Performance Standards<br />
• Demonstrate understanding <strong>of</strong> one-to-one correspondence<br />
while counting.<br />
• Show curiosity and independent interest in<br />
number-related activities.<br />
Number sense is the ability to think and work with<br />
numbers, and to understand their uses and relationships.<br />
This ability includes:<br />
87<br />
• distinguishing between small and large<br />
groups;<br />
• understanding the relationship between and<br />
among quantities;<br />
• using one-to-one correspondence; and<br />
• understanding operations such as adding<br />
and subtracting.<br />
Research indicates that the development <strong>of</strong><br />
number sense is the most important element in preschool<br />
mathematics (NCTM, 2000). The development <strong>of</strong> number<br />
sense and the understanding <strong>of</strong> operations provides the<br />
foundation for much <strong>of</strong> what is taught in mathematics.<br />
Young children come to preschool with many informal<br />
mathematical experiences, for example those <strong>of</strong> quantity<br />
or comparison. Their existing knowledge must be<br />
connected with the language, symbols and operations<br />
<strong>of</strong> mathematics (Griffin and Case, 1998; Gelman and<br />
Gallistel, 1978).<br />
In teaching preschool mathematics, the focus<br />
should not only be counting, reading and writing<br />
numbers. It is more important that children spend<br />
time creating a mental structure for number concepts.<br />
Encouraging thinking, making decisions and talking<br />
about quantity is the main goal (Kamii, 2000). Consider<br />
the experience <strong>of</strong> preparing a snack. Instead <strong>of</strong> giving<br />
specific directions such as, Please get 15 napkins, try<br />
asking children to gather enough napkins for everyone<br />
(Kamii, 2000). This encourages problem solving. The<br />
child may count the children; use trial and error with a<br />
random number; or create a one-to-one correspondence<br />
with the children or chairs. Whatever process is chosen,<br />
the experience <strong>of</strong> thinking and doing results from<br />
purposeful teaching that helps children learn to use<br />
numbers rather than just count.<br />
Understanding quantity is central to developing<br />
one’s mathematical thinking abilities. Multiple<br />
experiences in counting help children understand that<br />
the last number in a counting sequence represents the<br />
entire quantity. As children come to understand quantity,<br />
they begin to understand part and whole relationships<br />
and to see many ways to use and represent numbers.<br />
(For example: “There are 10 children here today. Four <strong>of</strong><br />
them are girls.”) This gradually leads to the child’s ability<br />
to see relationships around increasing and decreasing<br />
quantities (Ginsburg, Greenes and Belfanz, 2003).
