NVACS: Operations and Algebraic Thinking (4.OA)
Multiplication, Division with and without remainders, Multi-step
Problems
Practice for 4th Graders
4.OA.1
Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 X 7 as a statement that 35 is 5
times as many as 7 as 7 times as many as 5. Represent verbal statements of multiplicative comparisons
as multiplication equations.
4.OA.2
Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings
and equations with symbols for the unknown number to represent the problem, distinguish
multiplicative comparison from additive comparison.
4.OA.3
Solve multistep word problems posed with whole numbers and having while-numbers answers using the
four operations, including problems in which remainders must be interpreted. Represent these
problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of
answers using mental computation and estimation strategies.
4.OA.4
Find all factor pairs for a whole number in the range 1-100. Recognize that a whole number is a multiple
of a given one-digit number. Determine whether a given whole number in the range 1-100 is prime or
composite.
4.OA.5
Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern
that were not explicit in the rule itself.
RPDP has searched the web for content quality practice for you to use with the students to implement
the NVACS Curriculum. Many of these sites have received grants and or “Race to Top” funding to create
the instructional materials. As a requirement for receiving this funding they have to/or want to make
their material available for other educators. Because philanthropists and our tax dollars have paid for
these practice materials we should consider these valuable and shareable resources. These resources
are free and available for use by teachers in the classroom. Please explore what we found!

This site provides practice in several content areas. Please locate the thinking blocks website based
version and select, multiplication and division, addition and subtraction, (to meet the standards
4.OA.3.5) or fractions to practice 4th grade tape diagram (bar models) word problems. Within the site
you can select what type of word problem and model you would like to use.

Practice balancing a scale to practice and apply the concept of equality in using a visual interactive
model. These types of experience build the understanding of algebraic reasoning. (4.OA.3.5)

This site provides practice and feedback for students at their grade level for all content areas.
Technology based practice. This is set up as an adaptive reasoning format which is how the SBAC end of
the year tests for students will be given.
