Second Grade
Fourth Nine Weeks
Volume 4, Issue 4

Math Resources
and Ideas for Families
During these nine weeks,
second graders will learn to:
•
Know that all even numbers can be formed from
the addition of two equal addends. A student
should understand that 7 + 7 = 14 will result in an
even number as will 34 + 34 = 68.
•
Write an addition equation to represent an array.
For example, the picture below could be
represented by 3 + 3 + 3 = 9.
•
•
Partition a rectangle into the same-size squares
and identify the number of squares. A second
grader can split a rectangle into equal-size squares
and tell the number of squares the rectangle was
divided into.
Use addition and subtraction strategies to solve
two-step word problems within a hundred. For
example, Kim did cartwheels on Monday, Tuesday,
and Wednesday. She did thirty-five altogether. Kim
did 10 cartwheels on Monday. On Tuesday, she did 8
cartwheels. How many did she do on Wednesday?
This problem is a two-step problem because
students must first add the two numbers together
(10 + 8 = 18) and then figure out how far it is to 35
(35 – 18 = 17).
•
Fluently add and subtract within 20 using mental
strategies. By the end of second grade, students are
expected to have addition and subtraction facts
within 20 memorized.
•
Estimate lengths using units of inches, feet,
centimeters, and meters. For example, about how
many inches long is a pencil? About how many
centimeters long is your eraser?
•
Determine how much longer one object is than
another. For example, if a crayon measures 5 cm
and a pencil measures 15 centimeters, how much
longer is the pencil than the crayon?

Allow your child the opportunity to practice
partitioning rectangles into equal size pieces.
For example, if you are making brownies,
allow your child to assist in cutting them
(with a dull knife! Safety First!). Use paper
and have your child fold it into equal size
pieces.
•
Make estimating objects into a game by
guessing how long an object in your house is
in inches. Each player makes an estimate and
takes turns measuring the objects. For every
inch the player is off from the actual length,
he gets one point. The person with the lowest
score at the end is the winner. Once your
child is able to estimate inches, switch to
another measurement such as centimeters,
feet, and meters.
•
Measure and compare objects in your home.
For example, compare the shoe of an adult
and a child and ask your child, “How many
inches greater is the adult’s shoe than the
child’s shoe? How do you know?”
•
Continue to practice addition and subtraction
facts with your child. It is very important that
he or she can quickly and correctly recall
basic math facts.
•
As you help your child with homework, be
sure to ask them to explain the strategies
they are using. Remember the Kentucky Core
Academic Standards (KCAS) for mathematics
do not expect students to add or subtract
using the standard algorithm until fourth
grade. The strategies for solving addition and
subtraction using place value, properties of
operations, and the relationship between
addition and subtraction, develop number
sense in children, which is necessary as they
participate in higher level mathematics
courses.
