Third grade is a very important year for math learning, as students dive into multiplication and division. Specifically, students use math tools such as number rods, (units of blocks that represent a certain number), base blocks and tiles or marbles. This helps them truly understand the concepts underlying multiplication and division as they add together and divide different groups of objects. In doing this, students don’t just memorize their multiplication tables but instead understand what it means to multiply.  In addition, students also practice explaining these concepts when they detail, both orally and through writing, how they solve a problem. Third graders also begin to study fractions.

• Multiplies and divides numbers up to 100 and understands the relationship between multiplication and division.
• Understands that 3x5=15 and 5x3=15 (this is the commutative property of multiplication).
• Begins to memorize the product of all one-digit numbers so that she has memorized them all by the end of 3rd grade.
• Solves word problems that require two steps and more than one mathematical action. For example: If Scott has 9 cupcakes and 12 candies, how many cupcakes and pieces of candy can he give to 3 people so that each person has the same amount?
• Rounds numbers to the nearest tens or hundreds.
• Adds numbers up to 1,000.
• Understands and creates fractions and uses number lines to represent and compare different fractions.
• Solves problems involving time and measurement.
• Creates and uses graphs to represent data and answer questions.
