Day Four: Dividing Decimals - Positive and Negative Decimals and Fractions

Students in Math 6 today continued their work from yesterday's lesson dealing with dividing decimals. Yesterday we hit some bumps with our multiplication fluency as it pertained to dividing. Friendly numbers were once again used to help us get a quotient quickly.

The last ten minutes of class was used to view vocabulary using the Topic One Quizlet.

Math 6+ students worked with adding and subtracting positive and negative decimals and fractions. This skill allowed us to still work on our understanding of how calculating with integers works and builds fluency.

Standards addressed in today's lesson:

• 6.NS.B.3: Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation. (M6)
• 7.NS.A.1.B: Understand p + q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing real-world contexts.
• 7.NS.A.1.C: Understand subtraction of rational numbers as adding the additive inverse, p - q = p+ (-q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.
• 7.NS.A.1.D: Apply properties of operations as strategies to add and subtract rational numbers.
• 7.NS.A.2: Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.
