    Math - November/December News

    The students are currently focusing on addition and subtraction strategies.  They are learning a variety of strategies to solve equations and word problems.

    The children continue to focus on the rapid recall of facts through XtraMath.  They relate these facts to help them with larger number calculations. 

    If you know 5 + 9 = 14, then you know 50 + 90 = 140, 500 + 900 = 1,400 and so on. 

    The children are reminded to use this information to help them solve larger number equations.

    The students continue to practice the multiplication facts and division facts.  They complete a multiplication assessment at the end of each week.  Please continue to encourage your child to practice the facts.  

    We continue to focus on the patterns with multiplication.  The children are reminded about the products of numbers using the following:

    odd x odd = odd

    even x odd = even

    odd x even = even

    even x even = even

    The students are encouraged to continue to practice the multiplication facts.  This will greatly support their math work moving forward for the next six months of school.

     

    Math - September/October News

    Concord Road is using the K-4 Investigations math program this school year.  This incorporates the eight different mathematical practices:

    1.     Model with mathematics.
    2.     Use appropriate tools strategically.
    3.     Look for and make use of structure.
    4.     Look for and express regularity in repeated reasoning.
    5.     Attend to precision.
    6.     Construct variable arguments and critique the reasoning of others.
    7.     Reason abstractly and quantitatively.
    8.     Make sense of problems and persevere in solving them.

    We are currently in our first math unit: Understanding Equal Groups.  The third graders are currently learning about multiplication.  They are learning about the relationship between multiplication and repeated addition and skip counting.  The mathematicians are interpreting word problems and using a variety of strategies to solve math equations.  

    We are also building upon second grade concepts with a review of place value, addition, and subtraction.  We continue to observe that math is all around us! We are always looking for math in our daily lives and connecting it to the real world.

    The children are also learning that mathematicians use a variety of different strategies to get to the same answer.  There are many different ways to solve a problem. The children are sharing their different strategies with one another and discussing the similarities and differences between them.

    The children complete XtraMath most days.  This helps with the fluency of math facts.  Right now they are focusing on the fluency of addition and subtraction facts.  This helps build the rapid recall of facts. As mathematicians they will soon connect their knowledge and understanding of basic facts to help them solve more complex equations.  For example, if mathematicians know 1 + 7 = 8, then 10 + 70 = 80, 100 + 700 = 800, 1,000 + 7,000 = 8,000 and so on.  Mathematicians can also use this information to help them with subtraction.  For example, mathematicians know that 8 - 7 = 1, then 80 - 70 = 10, 800 - 700 = 100, and 8,000 - 7,000 = 1,000. Please continue to point out these mathematical relationships to your children.

    The mathematicians are also getting ready to learn about arrays. An array is an equal arrangement to group items.  The children will be connecting arrays to their multiplication work. For example, there are many ways to represent the multiplication equation with a product of 24 by 1 x 24, 24 x 1, 2 x 12, 12 x 2, 3 x 8, 8 x 3, 4 x 6, and 6 x 4. The mathematicians will begin to connect the dimensions of array cards to area.

    Finally, the children will soon begin to learn about the relationship between multiplication, division, and fact families.  They will read the language in word problems to determine if they are being asked to multiply or divide.  They will be encouraged to learn the multiplication facts soon as well.
