The concepts of more, less and same are basic relationships that contribute to children's understanding of number. Identify the one relationship that if a child is unable to use they may be at educational risk.

Equality Sign

Step-by-step explanation:

A child may be at educational risk if he is unable to use the equality sign as it is the basis for comparison of numbers.

Once a child can determine if two numbers are the same, we can then proceed to introduce comparisons of numbers. That is, either it is more than a stated number or less.

For example,

If number of apples=6, a child who understands this will know if 5 apples are less or more as appropriate.
