Math Resources and Ideas for Families
During these nine weeks,
third graders are learning to:
 Recognize a unit fraction (fractions with a numerator of 1) is
formed when a whole is partitioned into equal parts. For
example, if a rectangle is divided into four equal parts, each
section would form the unit fraction ¼. This standard includes
fractions greater than 1.
 Represent fractions on a number line. Students will learn to
show fractions using a number line. For example, if a child is
working with fourths, they should recognize the line should be
divided into four equal parts from 0 to 1. An example is below.
 Tell and write time to the nearest minute. In addition,
students will solve word problems involving addition and
subtraction of time intervals in minutes by representing the
problem on a number line. For example, Mary starts her dance
lesson at 4:45. If the lesson is 45 minutes long and it takes her 20
minutes to get home, what time will Mary get home? A student
might draw the number line below to solve.

Sharpen Your Skills with:
 Explain division as a set of objects partitioned into an equal
number of shares. For example, students can interpret 56 ÷ 8
Fractions
as the number of objects in each share when 56 objects are
1) Fill in the number line with the appropriate
partitioned equally into 8 shares.
fractions.
 Solve multiplication and division word problems within 100
using drawings and equations with a symbol for the unknown
number. For example, Mrs. Smith has 48 stickers. She needs to
share them equally with 8 students. How many stickers will each
student receive? A student could draw a picture like the one

below.
 Measure and estimate masses of objects using grams and
kilograms and liquid volume using liters. Students need to
understand the weight of a gram or a kilogram in relation to
everyday objects. A medium-sized paper clip or a dollar bill is an
example of two household objects that weigh a gram. A baseball
and a whole pineapple are two objects that weigh about a
kilogram (2.2 lbs.).
 Partition shapes into parts with equal areas. Express the area
of each part as a unit fraction of the whole. For example,
partition a square into 4 parts with equal area, and describe the
area of each part as one-fourth of the area of the shape.
 Generate measurement data by measuring lengths using rulers
with halves and fourths of an inch. Show data on a line plot.
Answers:
1) 1/8, 3/8, 5/8
2) 3/8
Multiplication
Anna picked 54 flowers.
a) Anna will put 6 flowers in each vase. How many
vases does she need?
b) If Anna charges $10 for each flower
arrangement, how much money can she make from
selling her flowers?
Answers: a) 9 vases
b) $90

Activities to Try at Home
 Use flashcards to practice multiplication and
division facts. Stores such as Dollar Tree and
Walmart sell premade sets or you can make
your own using index cards.
 Practice multiplication and division by using
paper plates and counters (cereal, pennies,
buttons, dry beans, etc.). For example, if the
problem is 5 x 6, use 5 plates and put 6
counters on each plate. Have your child
determine the product (answer) of 30. For
division, ask your child to count out a certain
number of counters and then share it equally
on the plates. For 45  9, have your child count
out 45 counters and then divide them equally
on 9 plates.
 Incorporate division story problems into reallife situations. For example, if there are 8
pieces of pizza and there are 4 people eating,
how many pieces will each person receive? You
may even let your child physically act out the
problem such as allowing the child to pass out
the pizza to see each person would get 2 slices.
 Practice how much time is elapsed in everyday
situations. For example, if you start baking
cupcakes at 4:45 pm and it takes 35 minutes to
cook, what time will they be finished? If we left
our house at 10:35 am and arrived at
Grandma’s house at 12:15 pm, how long did it
take us to drive there?
