** 5th GRADE NUMBER ACTIVITIES: OPERATIONS AND ALGEBRAIC THINKING**

**Write and interpret numerical expressions****5.OA.A.1 **Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.**Sample Activities:**

Target Number Dash

Numerical Expressions Clock

**5.OA.A.2 **Write simple expressions that record calculations with
numbers, and interpret numerical expressions without evaluating them.
For example, express the calculation “add 8 and 7, then multiply by 2”
as 2 x (8+7). Recognize that 3 x (18932 + 921) is three times as large
as 18932 + 921, without having to calculate the indicated sum or
product.**Sample Activity:****Equivalent Expressions Match**

**Analyze patterns and relationships****5.OA.B.3 **Generate two
numerical patterns using two given rules. Identify apparent
relationships between corresponding terms. Form ordered pairs consisting
of corresponding terms from the two patterns, and graph the ordered
pairs on a coordinate plane. For example, given the rule “Add 3” and the
starting number 0, generate terms in the resulting sequences, and
observe that the terms in one sequence are twice the corresponding terms
in the other sequence. Explain informally why this is so.**Sample Activities:Patterns on the Coordinate Plane Task Cards**

** 5th GRADE NUMBER ACTIVITIES: NUMBER AND OPERATIONS IN BASE TEN**

**Understand the place value system****5.NBT.A.1 **Recognize that
in a multi-digit number, a digit in one place represents 10 times as
much as it represents in the place to its right and 1/10 of what it
represents in the place to its left.**Sample Activity:****Place Value Concentration**

**5.NBT.A.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.

+ 9 x (1/100) + 2 x (1/1000)**Sample Activities:**Hunt for Decimals

b.
Compare two decimals to thousandths based on meanings of the digits in
each place, using>, =, and < symbols to record the results of
comparisons.

**5.NBT.B.6** Find whole-number quotients of whole numbers with up to four-digit 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.NBT.B.7 **Add, subtract, multiply, and divide decimals to
hundredths, using concrete models or drawings and strategies based on
place value, properties of operations, and/or the relationship between
addition and subtraction, relate the strategy to a written method and
explain the reasoning used.

**5.NF.A.2 **Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + ½ = 3/7 by observing that 3/7 < ½.

**Apply and extend previous understandings of multiplication and division to multiply and divide fractions****5.NF.B.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.

**Sample Activity:Interpret Fractions as Division**

**5.NF.B.4 **Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.

a.
Interpret the product (a/b) x q as a parts of a partition of q into b
equal parts; equivalently, as the result of a sequence of operations
a x q÷b. For example, use a visual fraction model to show (2/3) x 4 = 8/3,
and create a story context for this equation. Do the same with (2/3) x
(4/5) = 8/15. (In general, (a/b) x (c/d) = ac/bd)

**5.NF.B.5** Interpret multiplication as scaling (resizing) by:

a.
Comparing the size of a product to the size of one factor on the basis
of the size of the other factor, without performing the indicated
multiplication.

b. Explaining why multiplying a given number by a
fraction greater than 1 results in a product greater than the given
number; explaining why multiplying a given number by a fraction less
than 1 results in a product smaller than the given number, and relating
the principle of fraction equivalence a/b= nxa)/(nxb) to the effect of
multiplying a/b x 1**Sample Activity:**

**5.NF.B.6** Solve real world problems involving
multiplication of fractions and mixed numbers, e.g. by using visual

**5.NF.B.7** Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions.

a. Interpret division of a unit fraction by a non-zero whole number and compute such quotients. For example, create a story context for (1/3)÷4, and use a visual fraction model to show the quotient. Use the relationship between multiplication and division to explain that (1/3)÷4 = 1/12 because (1/12) x 4 = 1/3.**Sample Activity:**

Divide a Unit Fraction by a Whole Number

b. Interpret division of a whole number by a unit fraction, and compute such quotients. For example, create a story context for 4÷(1/5), and use a visual fraction model to show the quotient. Use the relationship between multiplication and division to explain that 4 ÷ (1/5) =20 because 20 x (1/5 )=4.**Sample Activities:**

c. Solve real world problems involving division of unit fractions by non-zero whole numbers and division of whole numbers by unit fractions, e.g. by using visual fraction models and equations to represent the problem.
