6.NS Apply and extend previous understandings of numbers to the system of rational numbers.

1. Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation.

2. Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with negative number coordinates.

a. Recognize opposite signs of numbers as indicating locations on opposite

sides of 0 on the number line; recognize that the opposite of the opposite of a

number is the number itself, e.g., –(–3) = 3, and that 0 is its own opposite.

b. Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes.

c. Find and position integers and other rational numbers on a horizontal or

vertical number line diagram; find and position pairs of integers and other

rational numbers on a coordinate plane.

3. Understand ordering and absolute value of rational numbers.

Page 2: Flipped Classroom Lesson Plan

a. Interpret statements of inequality as statements about the relative position of two numbers on a number line diagram. For example, interpret –3 > –7 as a statement that –3 is located to the right of –7 on a number line oriented from left to right.

b. Write, interpret, and explain statements of order for rational numbers in real-world contexts. For example, write –3 oC > –7 oC to express the fact that –3 oC is warmer than –7 oC.

c. Understand the absolute value of a rational number as its distance from 0 on the number line; interpret absolute value as magnitude for a positive or negative quantity in a real-world situation. For example, for an account balance of –30 dollars, write |–30| = 30 to describe the size of the debt in dollars.

4. Distinguish comparisons of absolute value from statements about order. For

example, recognize that an account balance less than –30 dollars represents a debt

greater than 30 dollars

7.NS Apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers.

1. Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram.

a. Describe situations in which opposite quantities combine to make 0. For example, a hydrogen atom has 0 charge because its two constituents are oppositely charged.

b. Understand p + q as the number located a distance |q| from p, in the positive

or negative direction depending on whether q is positive or negative. Show that a

number and its opposite have a sum of 0 (are additive inverses). Interpret sums of

rational numbers by describing real-world contexts.

c. Understand subtraction of rational numbers as adding the additive inverse, p –

q = p + (–q). Show that the distance between two rational numbers on the number

line is the absolute value of their difference, and apply this principle in real-world

contexts.

d. Apply properties of operations as strategies to add and subtract rational numbers.

Objectives: Students will be able to add and subtract integers on a number line; realize

that subtracting an integer is the same as adding its opposite, or its additive inverse;

recognize that the absolute value of a number is its distance from zero and that the

absolute value is always a positive value

Materials and Timing:

Students will be using Padlet app and Geometer’s Sketchpad app on an iPad. Students will

spend on an average 10 minutes video clip at home which is available on the class

website. For those who do not have internet access at home, send them a copy of the

video clip on a CD. Students will spend 60 minutes exploration activity in regular

classroom.

Scope and Sequence:

1. Students are expected to watch the video clip before coming to class.

2. With the use of Padlet app, the students are to this question: “How do you represent

real world situations using integers?" Have a whole classroom discussion on this

topic.

3. Ask students to consider the relationship between addition and subtraction of

integers as they work. As you are adding and subtracting integers using the

Sketchpad model, think about how adding and subtracting integers are

related. How are they similar? How are they different?

4. Assign students to computers and tell them where to locate Right or Left.gsp. Distribute the worksheet. Tell students to work through step 25 and do the Explore More if they have time. Encourage students to ask their neighbors for help if they are having difficulty with Sketchpad.

5. Let pairs work at their own pace. As you circulate, here are some things to notice.

In worksheet step 3 and for all activity questions, encourage students to write clear and detailed explanations using complete sentences. By clearly describing what they observe, students acquire a strong mental image of

Page 4: Flipped Classroom Lesson Plan

Flipped Classroom/BA Pearl

operations with integers. If time is limited, you might have students write their explanations for homework.

In worksheet step 8, have students predict what will happen in the Sketchpad model before pressing any buttons. What will the model of-6 + (-3) look like? Why? Try to get students to concentrate on the behavior of the model rather than on the numeric answer.

In worksheet steps 10 and 11, encourage students to explore these questions by dragging to change the values of the integers without pressing Reset. Students can quickly view several problems before making a conjecture. In worksheet step 12, students must interpret different parts of the Sketchpad model. As you walk around, observe students to be sure they understand each part and can model any problem they are given. When students successfully model all the problems, ask them to look for patterns. Students may notice that the sign of the answer is the same as the sign of the longer arrow. They may not recognize this as the integer with the greater absolute value; that’s okay. Students are focusing on the visual model at this time. Discuss absolute value later.

In worksheet step 14, students start subtracting integers. The concept of additive inverse is not explicitly named, but it plays a prominent role in the model. Ask students to think about why the second integer is flipped in a subtraction problem.

As students are creating new subtraction problems, ask them to predict what the model will do each time before pressing the action buttons. Can you predict what the model of this subtraction problem will look like? Why do you think it will act that way? Students can test their conjectures using the step-by-step buttons.

In worksheet step 24, ask students what patterns they see and how they could predict the answer from the two numbers being subtracted.

In worksheet step 25, students are asked to write an addition problem using the same first number and the same answer. Students can test their addition problems by going to page “Addition.” Switching back and forth between the two pages will reinforce the idea of using addition to rewrite a subtraction problem: To find the answer to a subtraction problem, you add the additive inverse (opposite) of the second number.

If students have time for the Explore More, they will investigate the behavior of addition and subtraction independent of specific values, and they will use special cases to identify the position of zero on the number line.

6. Gather the class. Students should have their worksheets with them. Begin the discussion by opening Right or Left.gsp and going to page “Addition.” Work through the different types of addition problems with the class.

Have volunteers model the problems they recorded for worksheet step 9. What happens in the model when you add two negative integers? Students may make this sample response: When adding two negative integers, the arrows both point left, so the answer is always negative. How does this compare to adding two positive integers? Students may reply that in both cases the arrows point in the same direction. With positive integers, the

Page 5: Flipped Classroom Lesson Plan

Flipped Classroom/BA Pearl

arrows point right. With negative integers, the arrows point l e f t . Next have volunteers model the problems in worksheet step 12. What happens in the model when you add a positive and a negative integer? Students may make the following response: If the negative integer is greater, the arrow pointing left will be longer, so the answer will be negative. If the positive integer is greater, the arrow pointing right will be longer, so the answer will be positive.

At this point, you may wish to introduce the term absolute value and the absolute value symbol. Absolute value is the distance a number is from zero. What represents the absolute value of a number in this model? Help students see that the length of an arrow is the distance from zero. What is the absolute value of -2? [2] What is the absolute value of 2? [2] Work through several problems with the class, each time focusing on the length of the arrow. Students should understand that opposites, or additive inverses, have the same absolute value. Can the absolute value of a number ever be negative? Students should realize that because distance is a positive value, the absolute value can never be negative.

When adding a positive and a negative integer, how can you look at the numbers and tell whether the answer will be positive or negative? Students may make the following responses.

The sign of the number with the longer arrow will be the sign of the answer.

The sign of the number with the greater absolute value will be the sign of the sum.

7. Go to page “Subtraction.” Have volunteers model subtracting two positive integers, a Negative and a positive integer, a positive and a negative integer, and two negative integers. How are adding and subtracting integers related? How are they similar? How are they different? Students may respond with the following answers.

When you subtract two integers, you flip the second number, so its arrow points the other way. You don’t do that with addition.

In subtraction, after you flip the second number, the model is similar to addition. The answer is where the second arrow ends.

Subtraction is just adding the second number flipped.

In subtraction you are adding the opposite of the second number.

8. If time permits, discuss the Explore More. Have students explain how they determined the position of zero.

9. Explain the different ways you can get a negative answer when you subtract two integers. You may wish to have student’s respond individually in writing to this prompt. Here are the possible ways: If both integers are positive, the second integer must be greater than the first one. If the first integer is negative and the second integer is positive, the difference will be negative. If both integers are negative, the second integer’s absolute value must be smaller than that of the first integer.

Evaluation of the lesson:

The whole activity is based on the objectives. The dynamic model (Geometer’s Sketchpad

software) helps students visualize integer addition and subtraction. The animation helps

the abstract concept easy to understand and remember. As long as the teacher circulate

and make sure the student grasp the concepts, I believe this lesson will be successful

along with routine and procedures already established in the classroom. The use of Padlet

app makes use of the time more efficiently than the regular post it notes.
