6th Grade Math - 1A

Here are the standards for 6th Grade 1A:

6.NS.1: Understand that positive and negative numbers are used 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 and compare quantities in real-world contexts, explaining the meaning of 0 in each situation.

• Idea: Number line activity. Prepare numbers on post-its and have the students place the numbers on a number line. Remember, it is the mathematical discussion that takes place that provides learning and understanding. Allow mistakes, and use them to promote discussion.
• Idea: Place numbers on construction paper from -10 to +10. Have students take turns do problems by coming up to the line and physically moving. Example. 3 - 7 = x. Student goes to the number 3 and moves 7 spaces to the left to arrive at an answer of x = -4. Students at seats could have a smaller number line copied and follow along with their fingers. Adding movement activates more of the brain, increasing retention!

6.NS.2: Understand the integer number system.  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. 

6.NS.8: Interpret, model, and use ratios to show the relative sizes of two quantities.  Describe how a ratio shows the relationship between two quantities.  Use the following notations: a/b, a to b, a:b.

• Idea: Bar models are great for solving ratio and showing the relationship between quantities.
