In grade three, students will continue to build their concept of numbers, developing 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 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. Activities 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
