Essential Math Mapping

Number Sense Module

 


Lesson 1

Operations with Whole Numbers

                

7NS1.2 Add, subtract, multiply, and divide rational numbers (integers, fractions, and terminating decimals) and take positive rational numbers to whole-number powers.

 

MR2.1 Use estimation to verify the reasonableness of calculated results.

Lesson 2

Decimal Numbers

7NS 1.2 Add, subtract, multiply, and divide rational numbers (integers, fractions, and terminating decimals) and take positive rational numbers to whole-number powers.

 

MR2.1 Use estimation to verify the reasonableness of calculated results.

Lesson 3

Fractions

 

7NS 1.2 Add, subtract, multiply, and divide rational numbers (integers, fractions, and terminating decimals) and take positive rational numbers to whole-number powers. 

 

7NS2.2 Add and subtract fractions by using factoring to find common denominators.

Lesson 4

Operations with Positive and Negative Numbers

7NS 2.5 Understand the meaning of the absolute value of a number; interpret the absolute value as the distance of the number from zero on a number line; and determine the absolute value of real numbers.

Lesson 5

Exponents

7NS 2.3 Multiply, divide, and simplify rational numbers by using exponent rules.

Lesson 6

Square Roots

7NS 2.4 Use the inverse relationship between raising to a power and extracting the root of a perfect square integer; for an integer that is not square, determine without a calculator the two integers between which its square root lies and explain why.

 

MR2.1 Use estimation to verify the reasonableness of calculated results.

Lesson 7

Scientific Notation

7NS1.1 Read, write, and compare rational numbers in scientific notation (positive and negative powers of 10) with approximate numbers using scientific notation.

Lesson 8

Percents and Applications

7NS1.3 Convert fractions to decimals and percents and use these representations in estimations, computations, and applications.

 

7NS1.6 Calculate the percentage of increases and decreases of a quantity.

 

7NS1.7 Solve problems that involve discounts, markups, commissions, and profit and compute simple and compound interest.

Lesson 9

Mathematical Reasoning

MR1.2 Formulate and justify mathematical conjectures based on a general description of the mathematical question or problem posed.

MR2.4 Make and test conjectures by using both inductive and deductive reasoning.

MR3.3 Develop generalizations of the results obtained and the strategies used and apply them to new problem situations.
