In grade 1, instructional time should focus on four critical areas: (1) developing understanding of addition, subtraction, and strategies for addition and subtraction within 20; (2) developing understanding of whole number relationships and place value, including grouping in tens and ones; (3) developing understanding of linear measurement and measuring lengths as iterating length units; and (4) reasoning about attributes of, and composing and decomposing geometric shapes.

Supporting Your Child in 1st Grade Math
The Council of the Great City Schools has created Parent Roadmaps to provide guidance to parents about what their child will be learning in Mathematics and how they can support that learning. These parent roadmaps also provide three-year snapshots showing how selected standards progress from year to year:

Standards for Mathematical Practice
The 2011 framework introduces
Standards for Mathematical Practice
These standards complement the content standards so that students increasingly engage with the subject matter as they grow in mathematical maturity and expertise throughout the elementary, middle, and high school years. These standards are the same at all grades from Prekindergarten to 12th grade.
An explanation of how the standards can be highlighted in Grade 1 can be found here
These eight practices can be clustered into the following categories as shown in the chart below:
|
Habits of Mind of a Productive Mathematical Thinker:
MP.1: Make sense of problems and persevere in solving them.
MP.6: Attend to precision.
|
Reasoning and Explaining
MP.2: Reason abstractly and quantitatively.
MP.3: Construct viable arguments and critique the reasoning of others
|
|
Modeling and Using Tools
MP.4: Model with mathematics.
MP.5: Use appropriate tools strategically.
|
|
Seeing Structure and Generalizing
MP.7: Look for and make use of structure.
MP.8: Look for and express regularity in repeated reasoning.

Content Standards to be covered in Grade 1
The focus of instruction in Grade 1 is determined by the Massachusetts 2011 Mathematics Curriculum Framework, which can be found on the
Department of Elementary and Secondary Education's website
