Identifying and creating patterns is a basic mathematical skill that is practiced in preschool and kindergarten classrooms. A pattern is defined as a sequence that repeats at least one time with the repetition continuing through the entire sequence. For example, you could create a basic AB pattern by alternating blue and red blocks (blue block, red block, blue block, red block, etc.) or an ABC pattern with a red block, blue block, yellow block, red block blue block, yellow block, etc.). Once simple patterns are learned, more complex patterns can be recognized and created. Patterns such as ABAC, ABBC or ABCD are examples of slightly more complex patterns. Your child’s imagination can really soar when he creates his own patterns. As long as the sequence repeats at least once and does not change, a pattern has been created.
