A new curriculum will be rolled out across NSW classrooms from next year, following the first comprehensive review in more than three decades.
Fresh English and mathematics syllabuses will be used across 300 public schools from January, with the remaining schools across the state set to fully adopt them by 2023.
Premier Dominic Perrottet on Monday announced students in kindergarten, year 1 and year 2 would be the first to benefit from the changes.
New curriculums for older year levels will be progressively released from 2021, with the government pledging to completely overhaul the K-12 curriculum by 2024.
"One of the most important things a government can do is provide a quality education and reform was needed to bring our curriculum into the 21st century," Mr Perrottet said.
"The new approach will ensure our youngest learners are provided with a solid foundation to grow from, with a focus on literacy and numeracy skills."
The curriculum for the first time also included explicit teaching examples, Education Minister Sarah Mitchell said.
"We heard clearly from teachers that navigating syllabuses was unnecessarily arduous," she said.
"The new online curriculum removes ambiguity for teachers ... this will be particularly helpful for early-career teachers."
Among the changes include a shift in focus from "sight reading" words - or learning them as a whole - to phonetically sounding them out, and an enhanced focus on handwriting in the early years of a child's schooling.
The new maths syllabus places emphasis on reasoning and advanced counting strategies.
The new curriculums also remove learning timelines, so students are not compelled to complete a certain stage each year.
"For example, some students will achieve stage 1 outcomes during year 1, while the majority will achieve them by the end of year 2," the Snew syllabuses say.
"Other students might not develop the same knowledge, skills and understanding until year 3 or later."
