• In 3rd grade, students are expected to master many new concepts. These concepts include:

    • Multiplying and dividing up to 10 × 10 quickly and accurately, including knowing the times tables from memory
    • Solving word problems using addition, subtraction, multiplication, and division
    • Beginning to multiply numbers with more than one digit (e.g., multiplying 9 × 80)
    • Understanding fractions and relating them to the familiar system of whole numbers (e.g., recognizing that 3 ⁄1 and 3 are the same number)
    • Measuring and estimating weights and liquid volumes, and solving word problems involving these quantities
    • Reasoning about shapes (e.g., all squares are rectangles but not all rectangles are squares)
    • Finding areas of shapes, and relating area to multiplication (e.g., why is the number of square feet for a 9-foot by 7-foot room given by the product 9 × 7?)
