Sea level and debt have what in common? How to introduce subtracting negative numbers to your learners! The video introduces word problems that relate to different subtraction situations. These problems create good scenarios to explain the double subtraction, such as removing debt. Each problem relates back to the number line to show that sometimes we have to add to subtract. This is the second video in a four-part series. Use other videos for more practice with subtracting integers.
A hard concept to teach is why a double negative becomes a positive. The number line in this video demonstrates how the minus sign relates to the distance between two numbers. Show your learners how subtracting a negative number means to find the distance between those two numbers which adds them together. Also shows the relationship between larger and smaller numbers and whether the answer will be positive or negative. This is the third video in a series of four about subtracting integers.
Have your mathematicians see how integer chips relate positive and negative numbers to different colors that "zero out". The video practices a variety of subtraction problems that show how subtraction can sometimes lead to addition. Have your learners create their own integer chips to follow along with the video and practice on their own. This is the first video out of a four-part series about subtracting integers.
Middle schoolers explore how to add and subtract integers. In this integer lesson students are broken into groups and participate in an activity that helps them investigate how to add and subtract integers.
In this subtracting integers worksheet, students complete problems and fill in charts that require them to subtract integers. Students complete 8 problems.
Middle schoolers use discs in order to add and subtract integers. There are manipulatives present so kinesthetic learners can access the curriculum. They also review the concept of the opposite of positive and negative numbers.
Students add and subtract integers. In this middle school mathematics lesson, students use two-color counters to explore the rules that govern addition and subtraction of integers.
Students solve subtraction problems using four operations. In this algebra lesson plan, students add, subtract, multiply and divide integers. The lesson plan focuses on negative numbers as they relate to subtracting integers.
Eighth graders brainstorm the differences between positive and negative numbers. They create a Venn diagram comparing numbers on an elevator to numbers used in a checkbook. Students watch a video from United Streaming to compare subtracting integers to elevators. They take notes during the film.
In this adding and subtracting integers worksheet, students review integer rules by completing 19 drill and practice questions. They work in pairs to compute the total left in a fictitious bank account after several withdrawals and deposits.
In this integer worksheet, students subtract integers to solve a set of 10 problems. Answers and hints are available on-line; a reference web site for additional resources is given.
For this subtracting integers worksheet, students complete 20 problems. Each problem includes three integers.
Students practice writing number sentences. After reading real world problems, they describe the same situation by writing a number sentence. Students use algebra tiles, or counters, to demonstrate the use zero pairs in solving equations. They use a building mat to model adding and subtracting integers.
Students add and subtract integers. In this algebra lesson, students discuss number sense as they sort numbers in the correct order. They analyze and label numbers differentiating between rational and irrational numbers.
Eighth graders add and subtract integers and solve real-life problems involving integers. They practice with many different problems in order to master this skill. They write expressions to help solve word problems.
Seventh graders explore the concept of adding and subtracting integers. In this adding and subtracting integers lesson, 7th graders use white and red beans to demonstrate adding and subtracting integers. Students play an on-line game where they must add the given numbers together to make zero.
Prealgebrarians use colored chips, stickers, and pencils to explore the world of integers. They discover absolute value, compare positive and negative integers, and apply operations to them. A detailed procedure for the three-part activity is provided, as well as pertinent worksheets with answer keys. Nice!
Review the concepts of additive inverses and adding positive and negative integers. Relate understanding to the subtraction of integers. This is done with either the use of "Algeblocks" (any square or tile manipulative should do) or a number line. The lesson calls for your class to sing a silly song as they walk the number line, which you could skip if your class is more mature. They also use calculators to grasp the skill. Worksheet links with practice exercises are included.
Using this instructional activity, your math class will review the rules for adding and subtracting integers. They decide whether the answers to addition and subtraction problems will be positive or negative and use the number line to help them visualize the solutions. There are 12 problems on this assignment that would be appropriate as homework.
Six pages prepare you to introduce your math stars to the addition and subtraction of positive and negative numbers. They drive a robot back and forth on an actual number line to represent the operations. If you don't have access to a robot, have your class imagine the scenario, or simply place a home-made representative on the appropriate place on the number line themselves. Sample problems and writing prompts are suggested to support the instructional activity.
