2nd Grade Math
Maryland College and Career Ready Standards
In the two years prior to Grade 2 students gained an understanding of whole numbers to 120,began to develop strategies for addition and subtraction, worked with non-standard measurement,and reasoned about attributes. Students are fluent in adding and subtracting within 10. Studentsalso have an initial understanding of place value of two-digit numbers.
In Grade 2 students apply the strategies for addition and subtraction they developed in earliergrades to larger numbers and develop more sophisticated computational strategies based onplace value, the relationship between addition and subtraction, and properties of the operations.
1. They solve addition and subtraction problems within 1000 by applying their experience withusing models. They develop, discuss, and use generalizable methods to efficiently and accuratelycompute sums and differences of whole numbers. They reach fluency in addition and subtractionwithin 100, and mental fluency in addition and subtraction within 20. Throughout Grade 2students extend their problem solving strategies to include one-and two-step problems involving allthe problem types (refer to the story structure table at the end of this document).
2. They are introduced to standard units of measure and estimation of length.
3. Students continue developing geometric concepts and spatial reasoning by composing and decomposing shapes with a new focus on examining sides and
