Answer to Question #114304 in Algebra for Felicia Ngubandze

Question

1. Discuss the following concepts which are important in the development of number sense:
1. Counting
2. Subitising
3. Relational skill

Answer 1

Solution.

1.Counting is the process of finding the number of elements of a finite set of objects.

The number can be verbal: that is, each number is spoken aloud (or mentally) to track progress. This is often used to count objects that are already present, instead of counting a variety of things over time.

The number can also be in the form of marks: we make a note for each number, and then count all the signs when the number is finished.

Counting can also be in the form of numbers with your fingers, especially when measuring small numbers. It is often used by children to facilitate counting and simple mathematical operations. Finger count uses unary notation (one toe = one unit), and thus limits the count to 10 (if you do not take into account the toes).

2.Subsidization is defined as the ability to instantly and automatically recognize small numbers without the need to actively count.

3.Relational skill is to look at the problem holistically before dealing with details, looking for relationships between numbers and operations, and considering the context in which the question is asked; choose or invent a method that takes advantage of one's own understanding of the relationships between numbers or between numbers and operations and will look for the most efficient representation for a given task; use benchmarks to estimate the value of a number; and declare the results for calculations in the normal process of displaying answers to be unfounded.
