Standard(s)
Standards for Mathematical Practice
1. Make sense of problems and persevere in solving them. Students
solve problems by applying their understanding of operations with
whole numbers, including the order of operations. Students seek
the meaning of a problem and look for efficient ways to solve it.
2. Reason abstractly and quantitatively. Students demonstrate
abstract reasoning to connect quantities to written symbols and
create a logical representation of the problem at hand. Students
write simple expressions that record calculations with numbers and
represent numbers using place value concepts.
3. Construct viable arguments and critique the reasoning of others.

Students construct arguments using concrete referents, such as
objects, pictures, and drawings. They explain calculations based
upon models and properties of operations and rules that generate
patterns. They explain their thinking to others and respond to
others’ thinking.
4. Model with mathematics. Students use base ten blocks, drawings,
and equations to represent place value. They interpret expressions
and connect them to representations.
5. Use appropriate tools strategically. Students select and use tools
such as estimation, graph paper, and place value charts to solve
problems with whole number operations.
6. Attend to precision. Students use clear and precise language
(math talk) in their discussions with others and in their own
reasoning. Students use appropriate terminology when referring to
operations with whole numbers.
7. Look for and make use of structure. Students use properties of
operations as strategies to add, subtract, multiply, and divide with
whole numbers. They explore and use patterns to evaluate
expressions. Students utilize patterns in place value and powers of
ten and relate them to graphical representations of them.
8. Look for and express regularity in repeated reasoning. Students use
repeated reasoning to understand algorithms and make
generalizations about patterns. Students connect place value and
properties of operations to fluently perform operations.
Standards for Mathematical Content
5.NBT.2 Explain patterns in the number of zeros of the product when
multiplying a number by powers of 10, and explain patterns in the
placement of the decimal point when a decimal is multiplied or divided
by a power of 10. Use whole-number exponents to denote powers of 10.
5.NBT.5 Fluently multiply multi-digit whole numbers using the standard
algorithm.
5.NBT.6 Find whole-number quotients of whole numbers with up to fourdigit dividends and two-digit divisors, using strategies based on place
value, the properties of operations, and/or the relationship between
multiplication and division. Illustrate and explain the calculation by using
equations, rectangular arrays, and/or area models.
5.NF.3 Interpret a fraction as division of the numerator by the
denominator (a/b = a ÷ b). Solve word problems involving division of
whole numbers leading to answers in the form of
fractions or mixed
numbers, e.g., by using visual fraction models or equations to represent

the problem. For example, interpret 3/4 as the result of dividing 3 by 4,
noting that 3/4 multiplied by 4 equals 3, and that when 3-wholes are
shared equally among 4 people each person has a share of size 3/4. If 9
people want to share a 50-pound sack of rice equally by weight, how
many pounds of rice should each person get? Between what two whole
numbers does your answer lie?

conversions to solve multi-step, real world problems.
I am learning to…
 Represent powers of 10 using whole number exponents

multiplying a number by powers of 10.
 Fluently multiply and divide decimal numbers by powers of ten and
explain the reasoning using the Base-Ten number system.
 Fluently multiply a 4 digit factor by a 2 digit factor using the
standard algorithm
 Find whole-number quotients of whole numbers with up to four-digit
dividends and two- digit divisors
 Use strategies based on place value, the properties of operations,
and/or the relationship between multiplication and division to solve
division problems.
