Number sense is the ability to use numbers and understand their specific values. Whether a student is counting by 1's or estimating a value, they are using number sense. Recognizing benchmark numbers, such as 10 and 50, is also considered number sense. Students begin to learn number sense at a very early age. Students learning number sense typically are in kindergarten to second grade.

Watch a car race and put the cars in the order they finished. This game helps young children practice ordinal numbers and placement.
Count Your Chickens - Counting chickens
Count Your Chickens - Counting chickens
Help Curious George count the chickens in the chicken pen. Click on the number of chickens you think there are, and then count them with the man in the yellow hat to double check your answer.
The Counting Game practices counting by 1's and skip counting. Choose a number (1-9) to count by, and click on each number in the pattern. (Eg: 9, 18, 27, 36...). The higher the number, the more points you earn.
This website provides a variety of counting games for teachers to use in their classrooms. For instance, teachers can give students a handful of beans to count, and students can then practice writing the numbers on a number line.
Help Curious George count how many objects equal the height of another object. This game may be challenging for students because it requires estimation as well as counting skills. If a student gets a question incorrect, the man in the yellow hat explains why this answer is wrong.
VA Standards of Learning
K.2: The student, given a set containing 15 or fewer concrete objects, will:
a) tell how many are in the set by counting the number of objects orally;
b) write the numeral to tell how many are in the set; and
c) select the corresponding numeral from a given set of numerals
Background Information from Curriculum Framework
- Counting involves two separate skills: verbalizing the list of standard number words in order (“one, two, three, ...”) and connecting this sequence with the objects in the set being counted, using one-to-one correspondence. Association of number words with collections of objects is achieved by moving, touching, or pointing to objects as the number words are spoken. Objects may be presented in random order or arranged for easy counting.
- Kinesthetic involvement (e.g., tracing the numbers, using tactile materials, such as sand, sandpaper, carpeting, or finger paint) facilitates the writing of numerals.
- Articulating the characteristics of each numeral when writing numbers has been found to reduce the amount of time it takes to learn to write numerals.
- Zero (0) is both a number and a digit. As a number, it plays a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, zero is used as a placeholder in systems.
- Conservation of number and cardinality principle are two important milestones in development to attaching meaning to counting.
- The cardinality principle refers to the concept that the last counted number describes the total amount of the counted set. It is an extension of one-to-one correspondence.
