Grade 1

Year at a Glance

In 1st grade, your child will build on last year’s work and gain important new skills. One of the most important outcomes for the year is to improve speed and accuracy adding with a sum of 20 or less and subtracting from a number 20 or less (e.g., 17 – 8).   Another important goal in 1st grade is adding with a sum of 100 or less; this will rely on understanding what the digits mean in a number such as 63 (namely, 63 is six tens and three ones). Working with multi-digit addition this year will set the stage for 2nd grade, when your child will be working with three-digit numbers and adding and subtracting with larger numbers.

A Sample of What your Child Will Be Working on in First Grade:

    • Solving addition and subtraction word problems in situations of adding to, taking from, putting together, taking apart, and comparing (e.g., a taking from situation would be: “Five apples were on the table. I ate some apples. Then there were three apples. How many apples did I eat?”)
    • Adding with a sum of 20 or less, and subtracting from a number 20 or less, for example by using strategies based around the number 10 (e.g., to solve 13 – 4, one can start with 13, subtract 3 to reach 10, and then subtract 1 more to reach 9)
    • Quickly and accurately adding with a sum of 10 or less, and quickly and accurately subtracting from a number 10 or less (e.g., 2 + 5, 7 – 5)
    • Understanding what the digits mean in two-digit numbers (place value)
    • Using understanding of place value to add and subtract (e.g., 38 + 5, 29 + 20, 64 + 27, 80 – 50)
    • Measuring lengths of objects by using a shorter object as a unit of length
    • Making composite shapes by joining shapes together, and dividing circles and rectangles into halves or fourths
