Does rote recitation of numbers alone impart knowledge of differences in magnitude?
As students learn the verbal counting sequence, some knowledge of the order of number words is gained. However, rote recitation of numbers alone does not impart knowledge of differences in magnitude (e.g., knowing that six comes after five doesn’t necessarily mean that the child knows that six is more than five).
Is counting by twos a pattern?
Counting by twos, fives, and tens are all mathematical patterns—and can make counting fun (and easier!). Even counting by twos and odd numbers constitute a pattern. All of these patterns and structure are supported by knowledge of counting.
