We hate to answer a question with a question, but it is applicable in this situation. Take a moment to answer the two questions below:
Why teach preschoolers how to read in preschool? Or Why teach preschoolers how to write in preschool?
They Have The Capability
The number one reason to start now is because they have the capability. In early childhood, children swap magical and egocentric thinking for a theory of mind, the capacity to accomplish a plan of action, and simple logic. In a remarkable feat, by the end of early childhood, children comprehend most of the grammatical rules that adults use so why not teach them memorisation rules and techniques? Preschoolers have the ability to memorise, retain and recall vast amount of information, better then most adults. All they need is an opportunity to learn memory rules just like how they learn grammatical rules.
Why not start later
Children are born with incredible capacity and desire to learn. What is becoming increasingly clear is that the first few years of life are the most critical in terms of physical brain development. We now know that there are various windows of opportunity for learning between birth and the age of preschool. This means that an enormous responsibility lies in the hands of parents and early years practitioners to teach preschoolers the necessary skills such as reading, writing and memorisation.
When you think about it, the fact that preschoolers learn a language, learn how to write, and learn to speak in a short period is quite surprising. As parents and preschool educators, we all want to help encourage our children to learn the skills they will need for a lifetime, such as reading and writing. However, many of us forget about teaching them memory skills. According to leading experts, children begin to form memory as young as two years old. That is why it crucial to teach them practical ways to encode, store and retrieve information.
Preschoolers also have a vivid sense of imagination. Imagination is key to remembering information. As we progress as adults, our imagination deteriorates, and so does our ability to remember effectively.
Learn More Faster
With the ability to memorise, preschoolers will be able to learn information at a much quicker pace. Would you instead your child take one month to learn and relearn information or remember that same information in 1 week?
Most important of all, children need to experience a sense of autonomy and confidence in their own memory abilities and achievements and develop good memorisation habits that will carry them forward in their primary school years.
