Since 2004, Singapore, the world's math leader, and most countries had
completely switched from the old Singapore Math to the new
and improved Singapore Math for 4th Grade / Primary 4.
Find out why Singapore schools have switched completely to the new
and improved Singapore Math.
All the primary schools in Singapore, the world's math leader, are
using the New Singapore Math textbook packages for 4th Grade / Primary 4.
Primary Mathematics For 4th Grade / Primary 4 Package is based on the Old
Singapore Math curriculum and is no longer used in any Singapore school
since 2004.
