Transcript of Structuring Number

Structuring Numbers
Learning about numbers and the way they work together is an incredibly important skill that helps advance students in their math thinking. Children need to be flexible with breaking apart numbers and seeing them as a whole.
Being flexible with building numbers and breaking numbers apart is called structuring numbers.


Levels
Children need to be fluent with structuring numbers in the following ranges:

Kindergarten 1-5
1st grade 1 - 10
2nd grade 1 - 20

Flexibility in the 1-20 range will help build student success with addition, subtraction, multiplication, and division.


Subitizing
One of the first steps to becoming flexible with numbers is the ability to look at an amount of dots (such as on dice, dominoes or playing cards) and
immediately
see the pattern, and name the number represented
without counting
. This is called
subitizing
.

Subitizing activities help students begin to group numbers, add numbers and learn the combinations of different numbers.
For example, children with fluency of number will look at a
6
and be able to recognize it as
5 and 1, 4 and 2, or 3 and 3
.


Visualization of Number
Visualization is an important part of developing fluency and flexibility with number structure. For this reason, children will benefit from frequently working with spatial patterns as we see on dice or dominoes, dot cards, fingers patterns and ten frames.


Developing Strategies
As children apply this knowledge they will begin to develop more efficient strategies for solving addition and subtraction task by moving from counting by 1 strategies to more advanced non-counting strategies.

An example would be 24 - 6. Rather than counting back by 1's to solve the problem, a child could automatically break apart the 6 into 4 and 2, allowing a possible strategy to be 24 - 4 equals 20. Then 20 - 2 equals 18, by applying the knowledge of 10 - 2 equals 8, and knowing the 10 + structure of the teens.


How to Help Your Child at Home
Have fun with your child and thinking about numbers!
Play games that involve patterns like dice and dominoes.
Practice finger patterns. " Show me ( 6 ). What is another way to make 6?"
Look for ways to get kids thinking about numbers in their world. For example when you see items in their world say, " How many apples in the bowl? 3 How many more would we need to make 5?"
