Developmental Milestones

5-6 Years

IMPORTANT MILESTONES: BY THE END OF SIX YEARS
(72 MONTHS)

In the early school years, you won't see dramatic changes in motor skills because this is a period of refinement, when coordination improves and fine motor skills are sharpened. But you will notice remarkable changes in social and thinking skills. Your child is now building on the base of skills developed during early childhood and moving toward greater independence, both intellectually and emotionally.

Here are some of the milestones you can expect of a 6-year-old:
The following information will provide a basic overview of patterns of development in the growing child.

Cognitive Development

  • moving toward abstract thinking
  • wants it all; has difficulty making choices
  • may reverse printed letters (b/d)
  • enjoys planning and building
  • doubles speaking and listening vocabularies
  • reading may become a major interest
  • increased problem-solving ability
  • interested in magic and tricks
  • longer attention span
  • enjoys creating elaborate collections
  • able to learn difference between left and right
  • can begin to understand time and the days of the week
  • likes taking responsibility for simple household chores
  • likes to make simple decisions
  • counts to 100

  • continues to refine concepts of shape, space, time, color, and numbers
  • begins to understand the difference between intentional and accidental
  • begins to understand differences of opinion
  • still has a short attention span (about 15 minutes maximum)
  • enjoys dramatic play

Language Development

Although language has vastly improved, when it comes to written language, it is common for six year olds to have word reversals or letter reversals. This is the result of perceptual motor skills that are not quite fully developed and are not necessarily an indication of dyslexia.

Ironically, schools today tend to push reading at the kindergarten level when many children are only five years of age or nearing the age of six. Yet, the cognitive changes that need to occur in order for a child to learn to read traditionally manifest somewhere around the age of 6 - 6 1/2 years of age.

Physical Development

  • able to learn to ride a bicycle

  • tires easily
  • dawdles much of the time
  • is fascinated with the subject of teeth
  • may become a more finicky eater
  • uses crayons and paints with some skill, but has difficulty writing and cutting
