“I Can” Help My Student
I can …
 understand that multiplication fact problems can be seen as comparisons of groups
(e.g., 24 = 4 x 6 can be thought of as 4 groups of 6 or 6 groups of 4). 4.OA.1

multiply or divide to solve word problems by using drawings or writing equations and
solving for a missing number. 4.OA.2

recognize that in multi-digit whole number, a digit in one place represents ten times
what it represents in the place to its right. 4.NBT.1

read and write larger whole numbers using numerals, words and in expanded form.
4.NBT.2

multiply two two-digit numbers. 4.NBT.5

find whole-number quotients and remainders with up to four-digit dividends and onedigit divisors. 4.NBT.6
Key Words to Know
 Algorithm - a step-by-step procedure for calculations
 Distributive Property - an algebra property which is used to multiply a
single term and
two or more
terms inside a set of parentheses.
 Digits – Any one of the ten symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9 used to write numbers.
 Dividend – The number that is to be divided in a division problem.
 Divisor – The number that divides the dividend.
 Division (repeated subtraction) – The number of times a number is subtracted from
another before no further rational subtraction can take place.
 Factors- A number that is multiplied by another number to find a product.
 Multiplicand- a number that is multiplied by another number multiplier. The number 2 is
the multiplicand in the statement 2 × 4 = 8. (the number of row)
 Multiplier –one of the factors in a multiplication equation. In the 9s equation, each of the
numbers that multiplies 9 is the multiplier. (the number of columns)
 Multiples –a number that is the product of a given number and any whole number.
 Partition division (fair-sharing/chunking) –division as the amount of shares to each group.
 Product –the answer to a multiplication problem 3 x 4=12, 12 is the product.

Parent Guide
What your student should know & do at home
Important Understandings and Concepts
What should my student already know before I begin…..
Your child should be able to :
Solve multi-step word problems using four operations
Fluently multiply and divide within 100 using strategies
Multiply one-digit whole numbers by multiples of 10
Multiply a whole number of up to four digits by a one-digit whole
number
Multiply two two-digit numbers
Divide up to four digit dividends by one digit divisors
Use number talks to reinforce properties of operations and mental
computation
Learning at a Glance
In this unit students will generalize place value to 1,000,000 and understand
relative size of numbers in each place. They will use models for multiplication
(equal-sized groups, arrays and area model), place value, and properties of
operations, in particular the distributive property, as they develop accurate
methods to multiply multi-digit whole numbers. They will select and
accurately apply appropriate methods to estimate and mentally calculate
products.
In addition, students will use deep understanding of the relationship between
multiplication and division to divide with up to four-digit dividends and onedigit divisors to find whole number quotients with remainders and determine
the meaning of the remainder within context of the problem. They will select
and accurately apply appropriate methods to estimate and mentally calculate
quotients.
Finally, students will solve multi-step word problems utilizing the four
operations and represent these problems using equations with a letter
standing for the unknown quantity.

Sample
Your class is collecting bottled water for a service project. The goal is to collect 300 bottles of
water. On the first day, Max brings in 3 packs with 6 bottles in each container. Sarah wheels in
6 packs with 7 bottles in each container. About how many bottles of water still need to be
collected?

Interactive Learning Lessons
The following are great interactive Math videos. Your student
can watch the videos alone or with you. Have your student
take notes while watching. Allow them to watch as many times
as needed.

Task
Robert and his family traveled from Atlanta, Georgia to Washington D.C. to visit the Martin
Luther King Monument. They traveled a total of 648 miles. It took them a total of 9 hours to get
to Washington, D.C. If they traveled the same route back to Georgia, about how many miles
would they drive? Explain your answer.
Recommended Children’s Literature
The use of children’s literature is equally important as problems and deserves some attention.
Use these books to integrate and enhance both language literacy and mathematical literacy for
an interdisciplinary connection during story time. These books can be checked out at your local
Atlanta-Fulton Public Library System www.afplweb.com
