Physical Development of the Preschooler

Page 2: Chapter 15

Lesson Essential Questions

1. What is the physical development that occurs in preschool children?

2. What are preschoolers’ gross and fine motor skills?

Page 3: Chapter 15

Body Growth & Development

Page 4: Chapter 15

Height & Weight• Most preschool children grow steadily at 2 1/2 -

3 inches each year. Girls are on average shorter than boys, but the difference is ½ or less.

• The rate of weight gain slows during the preschool years. Preschoolers gain 3-5 pounds per year. 75% of that weight gain is due to muscle development. Because boys have greater muscle development than girls, they are on average a pound heavier than girls.

Page 5: Chapter 15

Other Body Changes• A preschooler’s body proportions begin to look

more like an adult. The lower face grows more rapidly than the head. This helps the face look more like an adults.

• During the preschool years the waist is smaller than the shoulders and hips.

• The trunk grows to make room for internal organs.• The legs are about half of the length of the body.

(the same as an adult’s leg: body proportions)

Page 6: Chapter 15

Bones & Teeth• Bones continue to ossify and grow larger and

longer. • Deciduous (Baby) teeth begin to fall out between

4-5 years old.• Adult teeth grow under the gums. Malnutrition

can harm this growth. • Bones, muscles and joints are more prone to

injury in preschool children than in older children.

Page 7: Chapter 15

Organs• Hear rate slows and becomes steady.• Blood pressure increases• Breathing slows and becomes deeper• Digestive tract is not as mature as other

organs, and is irritated by high fiber foods & seasonings unlike an adult’s.

• The brain continues to grow, but at a slower rate than before.

Page 8: Chapter 15

Fat and Muscle tissue• The ratio of fat: muscle tissue decreases slowly.• Most of the baby fat will have disappeared by the

first day of Kindergarten with good nutrition and physical activity.

• The tall, lean body of the preschooler is strengthened. This is due to skeletal muscles and bones that are made stronger by ossification.

• Preschooler’s physical activity affects muscle development.

Page 9: Chapter 15

Why are a preschooler’s bones more prone to injury than those of older children?

Page 10: Chapter 15

Motor Development• Motor development improves due to physical

activity and increasing body growth & development.

• Better balancing skills• Eye hand coordination becomes more refined• Their reaction time becomes shorter• Able to perform more physical activities.

Through play these skills develop quickly.

Page 11: Chapter 15

Gross Motor Development

• Balance develops-this skill requires complex coordination processes.– Preschool children develop 2 kinds of balance:

• Dynamic balance-while moving (walking, balance beam)• Static balance-balance while still (stand on one foot)

• walking, running, jumping, climbing, throwing, catching, balancing, hopping, and skipping improve.

• Their actions become more advanced in all areas. – Two new actions help throwing: body rotation & weight

shift

Page 12: Chapter 15

What are some examples of the development of eye-hand coordination. What can a caregiver do

to promote this development?

Turn and discuss with a partner.

Page 14: Chapter 15

Fine Motor Development

• Preschooler’s ability to manipulate or work with by using the hands is still awkward but practice helps dramatically.

• Improved eye-hand coordination helps fine motor skills.

Page 15: Chapter 15

The order of development The 3 year old

• Can feed themselves using a spoon and fork but are rather messy.

• They can build towers from small blocks, but the towers are crooked

• Can draw straight lines and copy circles• Unbutton buttons and pull large zippers

Page 16: Chapter 15

The order of development

The 4 year old• Movements are steadier• May try to use knives when they feed themselves• Are able to build straight towers and place blocks

with steady hands• Begin to cut on the lines with scissors• Can comb their hair and wash their hands• Can begin to use laces, but probably not tie their

shoes.

Page 17: Chapter 15

The order of developmentThe five year old

• Eye-hand coordination is greatly improved• Right or left hand preference is definite• Uses a fork, spoon and knife to feed themselves• Can build towers and place other small toys

with skill.• Can make simple drawings freehand.• Can fasten large buttons and work large zippers

Intellectual Development of the Preschooler

Page 19: Chapter 15

Lesson Essential Questions

1. How does new thinking skills emerge in preschoolers?

2. What are the major concepts learned at this stage of mental development?

3. What are the increasing language skills of preschoolers?

Page 20: Chapter 15

A preschooler’s world broadens• Preschoolers can interact with more objects and people.• They observe more and develop more advanced ideas

about the physical attributes of things• They no longer rely on their senses and motor actions to

learn about their environment. They can now solve problems mentally.

• Growing language abilities are a bonus, not only in communicating but also in thinking in words.

• Piaget describes the 2nd stage of mental development as the preoperational stage.-the stage before logical thinking.

Page 21: Chapter 15

How Preschoolers Learn

• Figure 16-1: Piaget’s Stage of Cognitive Development • Pre-conceptual substage-2-4 year olds are beginning

to develop some concepts. They can form mental images, but many of these concepts are incomplete or illogical.

• Intuitive substage-able to grasp a problem’s solution by how they feel about it. Through their intuition they base their solutions on “feeling” their way through problems rather than on logic.

Page 22: Chapter 15

Piaget’s stages

Page 23: Chapter 15

Obstacles to Logical thinking• Preschoolers do not think logically yet.• They are egocentric.• They center their attention on only 1 part of an object or

event. They do not see all parts at the same time. (different sized glasses holding liquid)

• They focus on single steps, stages, or events rather than see the order of changes. (like seeing each frame of a film separately rather than a running story)

• They cannot follow a line of reasoning back to where it starts. They cannot retrace the steps to undo the task.

• Preschoolers link actions without using logic.

Page 24: Chapter 15

New Abilities Emerge

• Their problem solving skills depend on their memories of past sensory and motor experiences. The preschoolers’ thinking is marked by a number of new abilities-symbolic play, mental images, drawing, and language.

Page 25: Chapter 15

Symbolic Play

• Preschoolers play many pretend many games. Objects may stand for anything the child wants, roles may change too.

• These mentally changed roles and objects are symbols used to represent the pretend world and the child’s role in it.

Page 26: Chapter 15

Mental Images

• Mental images are symbols of objects and past experiences that are store in the mind.

• They are the pictures in the mind when words or experiences trigger the image.

• Mental images are private and internalized (thought about only)

• What mental images do you have when you hear these words…..

Page 27: Chapter 15

Drawing

• Preschoolers no longer scribble, they now attempt to draw objects and depict their world through drawings.

• Drawing is a step between symbolic play and mental images because preschoolers draw first and then decide what their pictures represent.
