The Common Core State Standards (CCSS) videos are designed to support states, schools, and teachers in the implementation of selected math standards. Each video is an audiovisual resource that focuses on one or more specific standards through examples and illustrations geared to enhancing understanding. The intent of each content-focused video is to clarify the meaning of the individual standard rather than to be a guide on how to teach each standard, although the examples can be adapted for instructional use.

Adding and Subtracting Integers: Grade 7 Mathematics Module 2, Topic A, Lesson 7
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

In this lesson, students recognize that the rules for adding and subtracting integers apply to rational numbers. Given a number line, students use arrows to model rational numbers where the length of the arrow is the absolute value of the rational number and the sign of the rational number is determined by the direction of the arrow with respect to the number line. Students locate the sum p + q of two rational numbers on a number line by placing the tail of the arrow for q at p and locating p + q at the head of the arrow. They create an arrow for the difference p - q by first rewriting the difference as a sum, p + (- q), and then locating the sum.

Adding and Subtracting Rational Numbers Without a Calculator: Grade 7 Mathematics Module 2, Topic A, Lesson 8

Rating
0.0 stars

In this lesson, students use properties of operations to add and subtract rational numbers without the use of a calculator. Students recognize that any problem involving addition and subtraction of rational numbers can be written as a problem using addition and subtraction of positive numbers only. Students use the commutative and associative properties of addition to rewrite numerical expressions in different forms. They know that the opposite of a sum is the sum of the opposites (e.g., - (3 + (-4)) = -3 + 4.

Addition of Positive and Negative Integers: Grade 7 Mathematics Module 2, Topic A, Lesson 3
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

In this lesson, students understand addition of integers as putting together or counting up, where counting up a negative number of times is counting down. Students use arrows to show the sum of two integers, p + q, on a number line and to show that the sum is distance | q | from p to the right if q is positive and to the left if q is negative. Students refer back to the Integer Game to reinforce their understanding of addition.

In this activity, students will use the CelSheet App that multiplies the fraction by “1” to help determine the common denominator. Then they will use what they have learned to add and subtract fractions without the same denominators. As an extension, they will use the LCM command to quickly obtain the best denominator to complete the operations.

This task is appropriate for assessing student's understanding of differences of signed numbers. Because the task asks how many degrees the temperature drops, it is correct to say that "the temperature drops 61.5 degrees." However, some might think that the answer should be that the temperature is "changing -61.5" degrees. Having students write the answer in sentence form will allow teachers to interpret their response in a way that a purely numerical response would not.
