Any one of the numbers …, -4, -3, -2, -1, 0, 1, 2, 3, 4, …. Integers are the entire set of whole numbers and their opposites (negative numbers).

Although not formally introduced until grade 6, children are exposed to positive and negative numbers in their everyday lives, even at a young age.  The winter months offer lots of possibilities to help children understand integers as the temperatures often dip below 0. This provides great opportunities to discuss negative numbers in a context that is meaningful and relevant during everyday routines like getting ready for school.
