First and Second Grade Math

Students work in small groups with students at their same grade level for mathematics.

In grade 1, critical areas for instruction include:

  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
  4. Reasoning about attributes of, and composing and decomposing geometric shapes

By the end of grade 1, students will:

  • Add and subtract within 20
  • Count to 120, starting at any number less than 120
  • Add within 100 including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10
  • Subtract multiples of 10 in the range 10-90

In grade 2, critical areas for instruction include:

  1. Extending understanding of base-ten notation
  2. Building fluency with addition and subtraction
  3. Using standard units of measure
  4. Describing and analyzing shapes

By the end of grade 2, students will:

  • Know from memory all sums of two one-digit numbers
  • Know from memory related subtraction facts of sums of two one-digit numbers
  • Count within 1000; skip count by 5s, 10s, 100s
  • Fluently add and subtract within 100 using strategies based on place value
  • Add and subtract within 1000, using concrete models or drawings and strategies based on place value
