What your child will learn and do in Grade 3 Mathematics

CREC Magnet Schools has adopted the Illustrative Mathematics curriculum (En Español).  In grade three, students continue to build their concept of numbers, developing an understanding of fractions as numbers. They 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. Activities in these areas include:

  • Understanding and explaining what it means to multiply or divide numbers
  • Knowing the rules of multiplying (such as 4 x 3 = 3 x 4)
  • Multiplying all one-digit numbers from memory (knowing their times table)
  • Multiplying one-digit numbers by multiples of 10 (such as 6 x 20 or 8 x 30)
  • Solving one and two step word problems using addition, subtraction, multiplication, and division
  • Understanding the concepts of area and perimeter
  • 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 that have the same numerator or the same denominator
  • Partitioning shapes into equal areas and naming the area of each part as a fraction
  • Telling time and writing time to the nearest minute
  • Solving word problems involving elapsed time
  • Measuring weights and volumes and solving word problems involving these measurements
  • Measuring length to the nearest ½ and ¼ inch
  • Collecting data, building a graph, and answering questions about the data
  • Understanding that shapes can have several different names based on their attributes (for example, a square can also be called a rectangle or quadrilateral) 

Comprehensive family support materials can be found in multiple languages on the IL Classroom website.  

 

Helping your child learn outside of school:    

  • Play math games with your child to build fluency. For example:
    • “I’m thinking of two numbers whose product is between 20 and 30. How many pairs can you think of?” Answers will include 8 x 3 = 24, 7 x 4 = 28, etc. Have your child explain the solutions and how they know they found all answers. 
    • Using a deck of cards, deal two cards and ask your child to multiply the two numbers before you do. Whoever says the product first, keeps the cards.
  • Find different examples of multiplication around your house. For example, a muffin tin has 3 rows of 4 cups or 12 total cups.
  • Have your child tell the time on the clock and then figure out how much time until dinner or practice.
  • Use everyday objects to allow your child to explore the concept of fractions. For example, use measuring cups. How many times do you have to refill a ½ cup measure to make 1 ½ cups?

 

Helping Your Child with Homework by asking questions or making suggestions 

  • Can you do some easier problems and go back to this one after?
  • What part of the problem is giving you trouble?
  • Let's read the problem together and make sure we understand what it is asking.
  • Can we draw a picture of the problem? 
  • Can we make up an easier problem that is similar to this? Then we can work our way up to this one.
  • Let’s take a 10 minute break and come back to this one.
  • What did your teacher say about this assignment?
