Math and the Young Child
                                    by Joan A. Cotter, Ph.D.

Babies can distinguish between 1, 2, and 3 objects and do this without counting. Even though
everyone seems to teach counting, it is not the best way to help children with beginning
number concepts.
Background
In the U.S. and Canada, counting is considered the basis of arithmetic; children engage in
various counting strategies for adding or subtracting: counting all, counting on, and counting
back. Japanese children, on the other hand, are discouraged from counting. Instead, they learn
to recognize and visualize quantities in groups of fives and tens. Their teachers consider
counting to be slow, unreliable, and unmindful of place value.
Visualization is the ability to produce visual mental images, or to see in one’s “mind’s eye.”
The vast majority of children are very visual. We also know from research that five-month-old
babies can distinguish between one to three objects. By twelve months, many babies can
discern up to four objects. These babies are visualizing and not counting the objects.
Counting, that ritual of pointing to each object while reciting a counting word, does not
contribute to a child’s understanding of quantity. If you ask a very young child to count four
objects and then ask him to bring you four, the child will only bring the fourth object, not the
entire quantity. In such counting the child presumes you are naming the objects and loses the
concept of the whole.
When we count to four, four includes one, two, and three. This accumulative activity is unique
to cardinal numbers; a child never experiences it in any other situation. For example, the letter
“C” does not include “A” and “B.” Therefore, avoid counting five or fewer objects; simply
refer to the number.
Some practical suggestions
Kinesthetic. Fingers are an excellent way to help children attach the number names to
quantities. (Note that this is not counting, but learning the names of quantities.) Indeed many
children have been taught to answer the question of old they are with a show of fingers. They
know that one of the joys of a birthday is being able to hold up one more finger to answer that
question. Use the left hand for quantities 1-5 (because we read from left to right) and the right
hand for 6-10. It does not matter which fingers to use on a hand.
The key to distinguishing five from four is observing that five has a middle while
four does not. Four- and five-year-olds love the concept of a middle. You might
say our middle finger is tallest to emphasize its middle position.                         4

To introduce 6-10, teach the “Yellow is the Sun” song (music notation on the Web
site, ALabacus.com). Ask the child to show the corresponding quantity with
fingers while saying it. You could also add appropriate motions for the other lines.
                                                                                           5

                                     Seven is five and two.

                                     Eight is five and three.                           9
                                     Hear the thunder roar.
                                     Nine is five and four.
         7                           Ducks will swim and dive.
                                                                           10
                                     Ten is five and five.
                                                      –J. A. Cotter

Visual. Just as our fingers naturally group in fives, our brains require grouping in fives to
recognize and visualize quantities. To understand the importance of grouping, try to mentally
see 8 apples in a line without any grouping–virtually impossible. Next try to see 5 of those
apples as red and 3 as green. Now you probably can imagine them. Thousands of years ago,
the Romans grouped their numerals in fives: VIII is 8. Piano music needs 10 lines, but
composers arranged them into two groups of five.
After the child has mastered the names of the quantities 1-10, use tally
sticks (craft sticks) for representing quantities. Show the child how to lay
out 3 sticks, about an inch (2.5 cm) apart, as shown. When the child can
both lay out 4 and identify 4, present 5 with the fifth stick laid horizontal-   3              5
ly across the remaining four sticks as shown. Continue through to 10. If
you go past 10, start a new row.
Give the child simple problems to solve with these sticks, “What is 4
apples and 3 more apples?” With the 7 sticks laid out, ask, “How can you
tell how much this is without counting?” The solution is to take one stick
from the 3 and give it to the 4, making 5 and 2, which we know is 7.                  4 and 3
Incidentally, Japanese children are taught to remember 4 + 3 by visualizing
the 4 and the 3 and mentally transforming them into 5 and 2.
Auditory. For numbers greater than 10, we need to group in tens. The
English language, especially the teens, does not make clear the tens                     7
structure of our number system. For example, fourteen does not give the
child an inkling that it is really “ten and four.” English, as well as other Indo-European
languages, is inconsistent in naming numbers 11-99.
Centuries ago, the Chinese changed their language to make the “name” of a number match its
“value.” So 11, 12, 13 are named ten-1, ten-2, ten-3, 20 is 2-ten, 21 is 2 ten-1, and so forth to
99, 9-ten 9. Other Asian languages also use value naming. Research shows this greatly helps
children understand place value. Therefore, teach your young child to count to 100 using this
“math” way of counting. Later on, teach the traditional names.
In summary, we need to help young children build on the visualization skills they exhibit as
infants and avoid rote counting. We must group in fives and use the math way of counting.

When the child can both lay out 4 and identify 4, present 5 with the fifth stick laid horizontal- 3 5 ly across the remaining four sticks as shown. Continue through to 10. If you go past 10, start a new row. Give the child simple problems to solve with these sticks, “What is 4 apples and 3 more apples?” With the 7 sticks laid out, ask, “How can you tell how much this is without counting?” The solution is to take one stick from the 3 and give it to the 4, making 5 and 2, which we know is 7. 4 and 3 Incidentally, Japanese children are taught to remember 4 + 3 by visualizing the 4 and the 3 and mentally transforming them into 5 and 2. Auditory. For numbers greater than 10, we need to group in tens. The English language, especially the teens, does not make clear the tens 7 structure of our number system. For example, fourteen does not give the child an inkling that it is really “ten and four.” English, as well as other Indo-European languages, is inconsistent in naming numbers 11-99. Centuries ago, the Chinese changed their language to make the “name” of a number match its “value.” So 11, 12, 13 are named ten-1, ten-2, ten-3, 20 is 2-ten, 21 is 2 ten-1, and so forth to 99, 9-ten 9. Other Asian languages also use value naming. Research shows this greatly helps children understand place value. Therefore, teach your young child to count to 100 using this “math” way of counting. Later on, teach the traditional names. In summary, we need to help young children build on the visualization skills they exhibit as infants and avoid rote counting. We must group in fives and use the math way of counting. ALabacus.com • JoanCotter@ALabacus.com rev Aug 2005
