Chapter 15 Physical Development of the Preschooler
Lesson Essential Questions • What is the physical development that occurs in preschool children? • What are preschoolers’ gross and fine motor skills?
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.
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)
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.
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.
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.
Why are a preschooler’s bones more prone to injury than those of older children?
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.
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
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.

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.
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
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.
The order of development The 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
Chapter 16 Intellectual Development of the Preschooler
Lesson Essential Questions • How does new thinking skills emerge in preschoolers? • What are the major concepts learned at this stage of mental development? • What are the increasing language skills of preschoolers?
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.
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.
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.
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.
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.
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…..
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.
