Day 47: Dividing Decimals / Rational Numbers on a Number Line / Adding and Subtracting Mixed Numbers

Today in Math 6: 1 & 3°, students completed a Quick Check dealing with adding and subtracting positive and negative decimals.  This is a skill that was assessed yesterday and practiced for several days.  

The focus for today's lesson was dividing decimals when a decimal was present in the divisor and dividend. Students learned how to multiply to eliminate the decimal in the divisor and mirror that calculation in the dividend.  

During Math 6 - 2°, students completed a Quick Check dealing with integers.  Once that was completed, Mr. Giomini introduced placing and ordering rational numbers on a number line.  Students arranged various rational numbers on a number in order from least to greatest.  

Students in Math 6+ completed a Quick Check dealing with multiplying mixed numbers that were both positive and negative.  Adding and subtracting mixed numbers was then introduced and practiced in class. 

Today's Learning Target(s): The student will be able to...

1. fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation. (1 & 3°)
2. use a rational number as a point on a number line. (2°)
3. understand that positive and negative numbers are used together to describe quantities having opposite directions or values. (2°)
4. recognize opposite signs of numbers as indicating locations on opposite sides of 0 on the number line.  (2°) 
5. use positive and negative numbers to represent quantities in real-world contexts. (2°)
6. solve word problems involving addition and subtraction of mixed numbers of fractions by fractions.  (7°)
7. fluently add, subtract, multiply, and divide numbers using the standard algorithm for each operation. (all classes)
