MIDDLE CHILDHOOD
6 – 11 YEARS OLD
3
PHYSICAL DEVELOPMENT
What gains in growth,
brain development,
and motor development
occur in school-age children,
and what are their nutritional
and sleep needs?
4
PHYSICAL DEVELOPMENT
1. HEIGHT & WEIGHT
 less rapid than in earlier years
 each year grows about 2 to 3 inches
 lower portion of body growing
fastest
 bones lengthen
 muscles become flexible
5
ASPECTS OF PHYSICAL DEVELOPMENT
6
2. NUTRITION & SLEEP
essential for normal growth and health
 2, 400 calories each day
 5 years old – 11 hours
 9 years old – 10 hours
 13 years old – 9 hours
Nutrition Problems in Middle
Childhood
 Little focus on eating
 Fewer meals with family
 Too few fruits and vegetables
 Too many fried foods
and soft drinks
• Poverty - lack of nutritional food
7
Nutrition Problems cont.
• By middle childhood, the effects of prolonged
and serious malnutrition are apparent in:
1. retarded physical growth
2. low intelligence test scores
3. poor motor coordination
4. inattention
• Malnutrition for many years - permanent
damage
8
3. BRAIN DEVELOPMENT
The brain structure is complex. It
is the product of the interaction
between genetic, epigenetic, and
environmental factors
9
BRAIN DEVELOPMENT
• As children acquire more complex abilities,
stimulated neurons increase in synaptic
connections and their neural fibers become
more elaborate and myelinated
• Loss in the density of gray matter
(closely –packed neural bodies)
–reflects pruning of unused dendrites.
• Balanced by a steady increase in white
matter
–axons or nerve fibers that transmit
information between neurons to distant
regions of the brain
10
11
• Cortex of temporal lobes thickens, at the
same time, thinning occurs in the rear
portion of the frontal and parietal cortex in
the brain’s left hemisphere.
• The corpus callosum thickens - leads to
improved communication between the two
cortical hemispheres.
• Lateralization of the cerebral hemispheres
increases over the school years.
Brain Development
• Brain functioning may also change
because of an increase in androgens
(male sex hormones) that occurs in
both boys and girls around age 7 to 8.

4. MOTOR DEVELOPMENT
IN MIDDLE CHILDHOOD
 Gross Motor Skills Improvements
1. Flexibility
2. Balance
3. Agility
4. Force
 Fine Motor Skills Gains
1. Writing
2. Drawing
13
Fine Motor Development
– Writing tends to be large at first, and legibility
gradually increases.
– Drawings show gains in
1. organization
2. detail
3. representation of depth
– School-age children not only
– (1) depict objects in considerable detail, they
also
– (2) relate them to one another as part of an
organized whole.

Ten-Year Old’s Drawing
17
Individual Differences
in Motor Skills
 Body build
 Family encouragement, expectations
 School & community lessons
available
18
Rough and Tumble Play
 Friendly chasing and play-fighting
(wrestling, kicking, tumbling,
grappling) accompanied by laughing
and screaming
 Boys play more physically active
games
 Girls favor games that include verbal
expression
19
Physical Education
• Physical education classes –
provide for exercise and play
on a regular basis – this
supports:
1. healthy bodies
2. a sense of self-worth as
physically active and
capable beings.
3. the cognitive and social
skills necessary for getting
along well with others.
20
Accidents in Middle Childhood
 Most common types:
 Motor vehicle
 Bicycle
 Pedestrian
 Prevention
 Teach safety
 Model safe behavior
 Require helmets
 Watch high-risk children more
21
22
EVOLUTIONARY STANDPOINT:
As the child gets older (11 years old), he hones
skeletal & muscle development that may channel
aggression & competition, &becomes a way to establish
dominance within the peer group.
