### Number Sense PowerPoint

```Number Sense
Developed by Carrie Ann Floyd
Plainfield School District
Objectives:
During this workshop we will:
 Review the revised Preschool Math Standards that relate to number sense.
 Define number sense and its importance as a building block for all future
mathematical learning.
 Review teaching strategies for number sense.
Opening Activity
Write your favorite number from 1-20 that has personal
significance to you on the post it.
For example: 4 - I have four children, 2 - I have two golden
retrievers.
Mingle with each other, sharing your number and why you chose
it.
Then, form groups based on the number you have.
After getting into your groups line up in order from
1-20.
What math skills did you use?
 Number recognition: “We both have the number 3.”
 Writing numbers: “I wrote down the number 3.”
 Saying counting words in order: Getting into the order 1-10.
 Understanding that written numbers are symbols for number
quantities.
 Understanding the relationship between numbers and quantities.
These skills all relate to number sense.
Number sense is defined as an intuitive feel for numbers and a common
sense approach to using them. It is a comfort with what numbers
represent, coming from investigating their characteristics and using them
in diverse situations. Number sense is an attribute of all successful users
of mathematics.
Preschoolers are beginning to develop number sense when they construct
a notion of oneness, twoness, and so on… Young children also have a
emerging concept of number when they see the relationship of one
number to another.

New Jersey’s Preschool Math Standards and
Number Sense
Standard 4.1: Children begin to demonstrate an understanding of
number and counting.
4.1.1 Count to 20 by ones with minimal prompting.
4.1.2 Recognize and name one digit written numbers up to ten with
minimal prompting.
4.1.3 Know that written numbers are symbols for number quantities and,
with support, begin to write numbers from 0 to 10.
4.1.4 Understand the relationship between numbers and quantities (i.e., the
last word stated when counting tells “how many”).
Preschool Teaching Practices to Promote
Number Sense
Encourage and support individual attempts to learn to count to 20 or higher.
Include and refer by name to written numbers in the classroom environment
during daily routines and in the context of large and small group experiences.
Intentionally refer to the symbol and number name when discussing numbers
(quantities) of objects.
Make materials and books that promote exploration of number quantities.
Preschool Teaching Practices to Promote Number
Sense (cont.)
Encourage children to compare numbers frequently through questions (e.g.,
“Are there more people riding in the bus or in the airplane?”) and graphing
(e.g., favorite colors, pets).
Provide manipulative and materials (e.g., print and digital material, sand
molds, tactile numeral cards, puzzles, counting books, hand-held devices
such as tablets, interactive whiteboards) and activities (e.g., tracing numbers
in sand, forming numbers with clay, recording data) that feature number
names and number quantities.
Provide a wide variety of writing materials for children to informally
explore writing numbers along with meaningful contexts for children to
write numbers on charts and graphs.
1. Cardinality
Recognizing that things come in quantities begins around 2 years old.
Children grasp the association between numbers and quantities by connecting
concrete objects with more abstract number words and symbols. (The idea of
“oneness” and “twoness.”)
Preschoolers learn cardinal number words by rote and can count up to 20 by
kindergarten.
At first they often say them in any order. They may omit some numbers and
repeat others.
Preschoolers will become familiar with numerical order if exposed to
numbers in counting songs, number books and natural opportunities.
2. Recognizing Number Symbols
Learning to read numbers symbols depends on how often children are exposed
to them.
Children need adults to explicitly identify and name numerals when they are
in the environment.
3. Writing Numerals
Children begin with the numbers that are the easies to draw or write.
(1,3,4,7) and then progress to more complex ones (2,5,6,8,9).
Perception and motor development may limit their ability.
Children may reverse numbers such as 2,3, 5.
When adults model standard numeral writing children will learn how to
write them on their own. There is no need to correct such errors.

Scaffolding Number Sense
Scaffolding is a term developed by the theorist Lev Vygotsy.
It means to provide children with support on their current level of
development while occasionally offering a gentle extension to the next level.
As you carry out these activities reflect on your experiences with children
and the developmental range of these skills seen in preschoolers.
How might children, at varying levels of development, respond to the
content and the materials?

many”).
 (a)Accurately count quantities of objects up to 10, using one-to one-
correspondence, and accurately count as many as 5 objects in a scattered
configuration.
 (b)Arrange and count different kinds of objects to demonstrate
understanding of the consistency of quantities (i.e., “5” is constant,
whether it is a group of 5 people, 5 blocks or 5 pencils).
 (c)Instantly recognize, without counting, small quantities of up to 3 or 4
objects (i.e., subitize).

or skip numbers
Say a different number than the last one
counted when saying “how many”
Count or eyeball two sets of objects and
say which one has more, fewer, less

one correspondence
Say the last numbers of objects tells
“how many”

and say by how many one is more or
fewer less than the other
* HighScope Numbers Plus Curriculum
Acknowledge when children count objects
correctly
Provide collections of more than 10 items for
use in play
Provide larger sets of objects to compare how
many more or fewer a set has or if they are the
same
Encourage children to explain how they figured
out how many more or less when comparing
sets
Implementation Plan
With your table, brain storm authentic opportunities for
children to develop number sense throughout the daily routine.
Write your ideas on index cards- include the activity and the
part of the day.
 Post each index card by the sign that corresponds to your
activity’s when, during the day, your activity would take place.
