Grade 2
Course overview
The big ideas in grade 2 include: extending understanding of the base-ten number system, building fluency with addition and subtraction, using standard units of measure, and describing and analyzing shapes.
The mathematical work for grade 2 is partitioned into 9 units:
Adding, Subtracting, and Working with Data
Adding and Subtracting within 100
Measuring Length
Addition and Subtraction on the Number Line
Numbers to 1,000
Geometry, Time, and Money
Adding and Subtracting within 1,000
Equal Groups
Putting it All Together
In these materials, particularly in units that focus on addition and subtraction, teachers will find terms that refer to problem types, such as Add To, Take From, Put Together or Take Apart, Compare, Result Unknown, and so on. These problem types are based on common addition and subtraction situations, as outlined in Table 1 of the Mathematics Glossary section of the Next Generation Learning Standards.
