Model of Project Given to Students Comparing • Create number line first. There are sample number lines in classroom. If you would like to use one of these please ask for one. -2 -3/5 -0.2 ½ 0.6 • If you count on this number line there are 10 marks from 0 to 1. Because of this each mark represents 0.1. • Once number line is created, comparison of numbers is very easy. The further to the right, the greater the number. • Two negative numbers: Use any of your two negative numbers to compare -2 __<__ -0.2 *ALL of this work would go in the Comparing Section of your poster or electronic presentation. Absolute Value • Remember that the absolute value is the distance from zero, and distance can only be measured in positive values. Use your 5 rational numbers and show the absolute values of each. Model yours from the examples below. −2 = 2 −0.2 = 0.2 1 1 = 2 2 The distance from -2 to zero is 2 units. Number Problems • Read the directions carefully. They describe exactly how the problems should be set up. Remember “like signs” means problems where both numbers are positive or both are negative and “different signs” or “unlike signs” means that one number is positive and one number negative. • You may use any of your 5 numbers as long as you match the directions. You may use each more than once. • I would suggest making blanks and filling them in. ____ + _____ = ____ + _____ = Review for Operations with Decimals: Below is a link of multiple videos that walk you through adding, subtracting, multiplying, and dividing decimals. Watch these if you need a reminder! https://www.khanacademy.org/math/arithmetic/decimals Review for Operations with Fractions: Below is the link to the online modules we used to review operations with fractions. http://mathtechyblog.blogspot.com/2014/07/fraction-review-withthinglink.html Real-life Problems • Think of real world contexts where positive and negative rational numbers are used and base your examples from these. • Temperature, money, elevation, sports, etc. are just a few that we have looked at in class Rules and Misconceptions • Misconceptions mean common mistakes that are made with operations with rational numbers. Think of mistakes that you have made, have seen friends and classmates make, or that you remember me pointing on during class.
