Singapore Primary Math: 1A-3B Answer Key
The Singapore Primary Math: 1A-3B Answer Key contains answers for Primary Mathematics U.S. Edition textbooks and workbooks. This answer key booklet contains answers for Primary Mathematics textbooks and workbooks from Level 1A through Level 3B.
Singapore Math divides the school year into two semesters. Students use the “A” level books for the first half of the school year. Students use the “B” level books for the second half of the school year. They use both “A” and “B” for a complete school year.
While you might not need the answer key for level one or even two, you will more than likely want it for level three. The economical cost of the answer key makes it handy to have for all levels one through three, considering most families want the key by the time students use level three.
