Then rate your understanding of the success criteria in your journal. So, the opposite integer of integer ‘a’, is ‘-a’ on the number line, but on the other side of 0. Student loses 5 points is indicated as -5.įor any given integer ‘a’, the opposite integer is found at the same distance from 0 on the number line, but on the other side. Write a positive or negative integer that represents the situation.ĭebt is an amount of money borrowed by one party from another.Ī student loses 5 points for not showing work on a quiz. Two numbers that are the same distance from 0 on a number line, but on opposite sides of 0, are called opposites. They are written with a negative sign (−). They can be written with or without a positive sign (+). How else can you represent numbers less than zero? Provide an example. The thermometers show temperatures on a vertical number line. ( It essentially means, “It’s gonna be cold bring your mittens and a warm hat.”ĭ. When used by weather forecasters in the U.S., it means “below 0☏”. Temperature to be below zero means cold weather starts. Can you think of any other situations in which numbers may be less than zero? Maintain OversightHow does this exploration help you represent numbers less than 0? What does it mean for a temperature to be below zero? Provide an example. Measuring in degrees fahrenheit and ReadingsĬ. What do all of the temperatures have in common? Seattle, Washington – 40 degrees Fahrenheitī. Honolulu, Hawaii – 110 degrees Fahrenheitĭeath Valley, California – 80 degrees Fahrenheit Match each temperature with its most appropriate location. The thermometers show the temperatures in four cities.Ī. Think about what each term might mean and record your thoughts. The following vocabulary terms are defined in this chapter. Plot and connect the points to make a picture.Ĭreate your own “dot-to-dot” picture. Why might g-force, pressure, and temperature be important considerations for making your decision? Integers, Number Lines, and the Coordinate Plane Getting Ready for Chapter You will determine which of the three CubeSats is the best option for a mission. You will be given information about three different types of Cubesats that you can purchase. What would happen to a CubeSatthatcannot withstand a g-force of 6? a g-force of 0?Īfter completing this chapter, you will be able to use the concepts you learned to answer the questions in the STEAM Video Performance Task. Why can g-forces be as high as 6 during a rocket launch and as low as 0 in space?ģ. e table shows the g-forces on a CubeSat at three points in time. Tony says g-forces are a measure of how heavy you feel. For what fields of study do you think CubeSats can be used?Ģ. Watch the STEAM Video “Designing a CubeSat.” Then answer the following questions.ġ. Each CubeSat has the dimensions shown and a mass of no more than 1.33 kilograms. Integers, Number Lines, and the Coordinate Plane STEAM Video/Performance TaskĪ CubeSat is a type of miniature satellite that is used for space research.
