GRADE THREE MATHEMATICS - COMMON CORE STANDARDS
In Grade Three, students will continue to build their concept of 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 to solve word problems. Students will also make connections between the concept of the area of a rectangle and multiplication and addition of whole numbers, and develop an understanding of fractions as numbers. Objectives in these areas will include:
- Understanding and explaining what it means to multiply or divide numbers
- Multiplying all one-digit numbers from memory (knowing their times table)
- Multiplying one-digit numbers by multiples of 10 (such as 20, 30, 40)
- Solving two-step word problems using addition, subtraction, multiplication, and division
- Understanding the concept of area
- Relating the measurement of area to multiplication and division
- Understanding fractions as numbers
- Understanding and identifying a fraction as a number on a number line
- Comparing the size of two fractions
- Expressing whole numbers as fractions and identifying fractions that are equal to whole numbers (for example, recognizing that 3⁄1 and 3 are the same number)
- Measuring weights and volumes and solving word problems involving these measurements
- Representing and interpreting data
The Grade Three math curriculum will incorporate the Standards for Mathematical Practice that will support the Common Core State Standards.
This overview for Mathematics, provided by the Council of the Great City Schools, reflects how the Common Core State Standards have guided our development of a rich and comprehensive curriculum for our students.
