We have learned that on a horizontal number line, the positive direction is to the right and the negative directions to the left. On a vertical number line, the positive is up, and the negative is down. We can use subtraction of a positive number to represent a decrease. To subtract a positive rational number on a number line, we start at a point for the first number (minuend) and draw an arrow moving in the negative direction for the second number (subtrahend), to the left. Adding a negative is the same as subtracting a positive. We show examples of using a number line to find the difference for subtracting a positive number. We show how we can draw our number line to fit the equation. We review how the Commutative Property does not work for subtraction. 7th Grade Math Course https://www.youtube.com/playlist?list=PLKi4WTp6PRGWxBDwfqly2mFnLNfpAU8UV This video and its contents are the property of JoAnn's School and is protected under U.S. copyright law.

A pattern is an ordered set of numbers or objects; the order helps us predict what will come next. Each number in the pattern is a term. A pattern will have a rule that will help us to find an unknown term. A sequence is an ordered list of numbers. So, a numerical pattern is a sequence. We can identify the relationship between two numerical patterns. We find a rule to write the first few terms in each sequence. Using the two sequences, we can write number Pairs and then find a rule that relates one sequence to the other. The rule for a pattern may contain addition, subtraction, multiplication, or division. Some patterns may even contain a combination of these operations. If the terms of a pattern of increasing, the rule may involve addition or multiplication. If the terms of a pattern or decreasing, the rule may involve subtraction or division. We complete sequences and find the rule for each sequence, then we find the rule that relates the sequences to each other. We see how we can use division of a whole number and multiplication of a fraction to equal the same value. 5th Grade Math 9.1, Line Plots & Fractional Averages https://youtu.be/_V83UezEyPw 5th Grade Math 9.2, Ordered Pairs, Identify & Plot Points on a Coordinate Grid https://youtu.be/viC3uKc1BU8 5th Grade Math 9.3, Graph Data on a Coordinate Grid https://youtu.be/rbUK_DdJRNs 5th Grade Math 9.4, Line Graphs https://youtu.be/Ua3CmWiFZKI 5th Grade Math Playlist https://www.youtube.com/playlist?list=PLKi4WTp6PRGX8NtQpzliTlMceQT1ua24f I'm using the Houghton Mifflin Go Math! 2015 copyright textbook for this playlist.
