Grade 3

What They Need To Know

In math, students develop an understanding of fractions as numbers. They will learn the concepts behind multiplication and division and apply problem-solving skills and strategies for multiplying and dividing numbers up through 100.

In English Language Arts, students will think, talk and write about what they read in a variety of articles, books and other texts. In writing, students will pay more attention to organizing information, developing ideas, and supporting these ideas with facts, details and reasons.

Math

Multiplication

Students understand that 15 tens = 5 tens + 10 tens (or one hundred).

Students use their understanding of place value as a strategy for multiplying one-digit numbers by multiples of ten. This will prepare them to multiply two multi-digit numbers in grade four.

Fractions

Students begin to understand that fractions are sometimes the same quantity as a whole number (8⁄4 = 2) and whole numbers can be expressed as fractions (3= 12⁄4).

Help children learn outside school

1. Play math games with your child. For example: "I'm thinking of two numbers whose product is between 20 and 30. How many pairs can you think of that would satisfy this problem?" Have your child explain the solutions. How does he or she know that all the number pairs have been identified?

2. Encourage your child to write or describe numbers in different ways. For example: "What are some different ways to make 1,450?"

1,450 = 1 thousand, 4 hundreds, 5 tens, and 0 ones, or 1,000 + 450, 14 hundreds and 50 ones, 13 hundreds + 15 tens, etc.

3. Use everyday objects to help your child explore fractions. For example: Use measuring cups to have students demonstrate how many 1⁄3's are in a whole, how many 1⁄4 cups you need to make 1 1⁄4 cups, or how many times you have to refill a ½ cup measure to make 1½ cups.
