Five Principles of basic counting is introduced to help children to grasp the properties of numeracy (Gelman & Gallistel, 1978).
•Map each element of the counted set onto one and only one number (numeron);
•Order the numbers and use the order to map items to be counted.
•The order in which different elements are mapped is irrelevant to the counting process;
•Counting applies to all sorts of physical objects;
•The last number (numeron) used during a count represents a property of the entire set.

Children do not realize that colours are nameable properties(Sandhofer & Smith, 2001; Soja, 1994). Along with learning what each colour is called, children need to understand what colour represents; it’s not size, nor shape, nor the name of the object, nor the texture, not the number of things showing. Constant repetition and expanding on what colours are and what they are not will help any child to understand what the actual word colour means.

Lead children to understand the dimensional adjectives (e.g. the opposing pair of words: high and low) are the class of words that refer to the perceptible properties of individual objects(Carey, 1982; Gasser & Smith, 1998).

Introduce 10 different shapes to children. For each of the shapes introduced, demonstrate the non-integral attributes (e.g. size and orientation) and derive the real objects to different shapes.

Children often find thematic relations between objects to be more salient(Markman & Hutchinson, 1984). The words are introduced in different themes. Once the words are introduced, the words are placed in problem solving activities for children to engage with the words regularly. In addition, the words are also used in various contexts to help the children’s to broaden their knowledge (e.g. the word “dog” has to match with different kind of dogs.)

Motor learning theory emphasizes that skills are acquired using specific strategies and are refined through a great deal of repetition and the transfer of skills to other tasks Croce(Croce & DePaepe, 1989).
Opportunities of a new motor skill are extremely important in moving a skill from the level of needing conscious attention in its use to the level of spontaneous and automatic use.

A child’s interest in an activity-
It is meaningful; It is significance for the child.
Hand skill intervention cannot be done to a child; it must be done with the child’s belief that he or she can be successful in accomplishing the activities presented (Pehoski, 1992).

Self-care and hand skill
• Eating
• Dressing
• Bathing
• Toileting
+
Three stages of learning to acquire a new skill –
•Exploratory activity
•Perceptual learning and feedback acquired from previous
tasks performed. Actions initially tried and ineffective are
discarded.
•Discovery of the optimal solutions & generalizes movement
patterns to other tasks

The learning orientations:
Intra-modal comparison
Intermodal comparison
Haptic - VisualHaptic – Haptic
Visual - Visual
The child looks at an object they are manipulating, they see the object from different points of view and can learn
about its properties.
The child acquires
tactile and kinesthetic information about the
object through active touch.
The ability to use visual imagery to improve
haptic recognition and memory of objects is
thought to contribute to children’s ability to
recognize objects on tests of haptic perception and
reproduce objects through drawings

In-Hand Manipulation Skills
-Finger-to-palm translation
-Palm-to-finger translation
-Shift: Slight adjustment of the object on or by the fingers pads
-Simple rotation: Turning or rolling the object 90 degrees or
less, with the fingers acting as a unit
-Complex rotation: Turning an object over using isolated finger
and thumb movements
