Day 117: MAD / Compare Rates / Appropriate Use of Statistical Measures

Today in Math 6: 1 & 3°, students continued their work with mean absolute deviation. Mr. Giomini created a table that might better help the students organize their work when creating working with several data values and calculating their mean absolute deviation.  

During Math 6 - 2°, students used the knowledge attained from Lesson 10.1 and 10.2 to now advance into Lesson 10.3: Compare Rates.  Students extend their knowledge and fluency when working with unit rates to begin looking for better deals by comparing multiple rates.  


Math 6+ students determined the most appropriate measures of center and variability to describe a given data set based on the context in which the data were collected.  

  
Today's Learning Target(s): The student will be able to...
  1. understand the concept of a unit rate a/b associated with a ratio a:b with b not equaling 0. (2)
  2. use ratio and rate reasoning to solve real-world and mathematical problems. (2)
  3. give quantitative measures of center (median and/or mean) and variability (interquartile range and/or mean absolute deviation). (1, 3, & 7)
  4. recognize that a measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation described how its values vary with a single number. (1, 3, & 7)
For Evening Practice, the student is expected to complete:
1.     Math 6(1&3°): 
o    Complete page 801 and 802.
o    Work towards 75% mastery on Khan Academy (6th Grade)
2.     Math 6(2°): 
o    Complete page 491 (1 - 3) and page 492 (10).  
o    Work towards 75% mastery on Khan Academy (6th Grade)
3.     Math 6+: 
o    Complete page 795 and 796.
o    Work towards 50% mastery on Khan Academy (7th Grade)
4.     All Classes: > 10 minutes meaningful practice at Khan Academy.
