Student prior knowledge

Prior to starting third grade Singapore Math, students should already know how to relate three-digit numbers to place value, use place-value charts to form a number, and compare three-digit numbers. The initial lessons in the Singapore Math 3rd Grade are both a review and an extension of content covered in the prior grade that includes mental addition of a 1-digit number to a 2-digit number and counting by 2s, 5s, and 10s.
