Second-grade math teaches important skills that children can use in everyday life.

Second-graders are rapidly becoming more proficient in math as they master basic concepts such as arithmetic and subtraction, according to child psychologist Robin Harwood in her textbook "Child Psychology." First grade prepares children to do simple number operations, while second grade has a strong focus on understanding the relationships between numbers, rather than memorizing solutions to problems. Students will progress to more complex addition and subtraction and will gain a deeper understanding of place value.

### Relationships Between Numbers

Second-graders strongly focus on learning about the relationships between numbers and understanding a number's place value. They also learn how to tell whether a number is greater than, equal to or less than another number. They begin learning about basic fractions, such as one-half and one-third, and grow to understand the concept that a fraction is less than a whole.

### Time

There's an increased focus on understanding and measuring time in second grade. Students will learn how to read a calendar and review how to tell time on an analog clock. Students will be expected to quickly give answers to questions about the time and date and will need to understand the relationship between different amounts of time -- 24 hours make a day, and a day is shorter than a year, for example.
