Common Core Math Standards for Second Grade

Numbers and Operations

The standards explain what children should be able to understand and do by the end of each grade.

The box on the left lists the standards teachers are using, and the box on the right is what you can do at

home to support what children are learning in the classroom.

What does this mean and what can I do at home to help my child develop these

skills?

 Explain to your child that 100 is the same as a bundle of 100 “ones” or 10

“tens” and it is called a “hundred”.

 Help your child understand that a three-digit number represents amounts of

hundreds, tens, and ones. For example, 706 equals 7 hundreds, 0 tens, and

6 ones

hundreds

tens

ones

 Count to 1000 with your child using skip counting by 5’s : 5, 10, 15, 20…, by

10’s: 10, 20, 30, 40…, and by 100’s, 100, 200, 300, 400…

 Show your child how to read and write numbers to 1000 using tens, 10, 20,

30… and ten, twenty, thirty….

 Show your child what these symbols mean: > is more than; < is less than,

and = means the same as. Compare numbers and use those symbols. For

example, which symbol would we use to compare 20 and 30? 20 < 30; or 30

> 20 are both correct answers

 Help your child practice adding numbers up to 1000. Add four two digit

numbers. Help her to see and understand the place value of the numbers –

ones or tens, that we add ones together, and tens together, and that

sometimes it is necessary to convert ones into a ten and ones when adding

numbers.

 Help your child practice adding 10 or 100 to numbers and subtracting 10 or

100 from numbers in her head, explaining how it changes the number in the

tens column by one. For example, adding 10 to 20 changes the 2 (tens) to 3

(tens), and adding 100 to 350 changes the 1 (hundreds) to 4 (hundreds).
