Unit 1: Factors, Multiples and Arrays Can you draw all the possible arrays for this number? (eg: 20, 30, 50, 100) How do you know that you’ve found all the possible arrays? What are some of the multiples of (3,5,6,8,9)? How did you find the multiples? What strategies did you use to find those multiples? Can you find all the factors for (12, 24, 36, 48, 50)? How do you know that you’ve found all of the factors of that number? Unit 2: Describing the Shape of the Data How can you measure a person’s height accurately? How can you collect and organize a set (or sets) of data? How can you accurately represent a set (or sets) of data? From your table or graph of the data you collected, what do you notice about the data? What do you think would be a typical number? Why do you say that? Give proof from your data to support your thinking. What landmark numbers can you find to describe your graph? median range (highest – lowest number) mode Is the data close together or spread out? Are there any clusters or clumps of data? Are there any outliers? (Use the math dictionary on the class blog to help with this vocabulary) Create your own survey: Design a clear survey question. If you can, compare two different groups (eg: males/females, adults/children, Thailand/USA) Collect data and organize it clearly (eg: tally chart, table) Clearly represent the data (eg: line plot, bar graph) Describe the data (eg: range, median, mode, clusters, spread, outliers) Write a conclusion for your data. What did you find out?

   Unit  1:  Factors,  Multiples  and  Arrays  

• Can  you  draw  all  the  possible  arrays  for  this  number?  (eg:  20,  30,  50,  100)  

• How  do  you  know  that  you’ve  found  all  the  possible  arrays?  • What  are  some  of  the  multiples  of  (3,5,6,8,9)?  • How  did  you  find  the  multiples?  What  strategies  did  you  use  to  

find  those  multiples?  • Can  you  find  all  the  factors  for  (12,  24,  36,  48,  50)?  • How  do  you  know  that  you’ve  found  all  of  the  factors  of  that  

number?    

Unit  2:  Describing  the  Shape  of  the  Data  • How  can  you  measure  a  person’s  height  accurately?  • How  can  you  collect  and  organize  a  set  (or  sets)  of  data?  • How  can  you  accurately  represent  a  set  (or  sets)  of  data?  • From  your  table  or  graph  of  the  data  you  collected,  what  do  you  

notice  about  the  data?  • What  do  you  think  would  be  a  typical  number?  Why  do  you  say  

that?  Give  proof  from  your  data  to  support  your  thinking.  • What  landmark  numbers  can  you  find  to  describe  your  graph?  

-­‐median  -­‐range  (highest  –  lowest  number)  -­‐mode  Is  the  data  close  together  or  spread  out?    Are  there  any  clusters  or  clumps  of  data?    Are  there  any  outliers?  (Use  the  math  dictionary  on  the  class  blog  to  help  with  this  vocabulary)  

  Create  your  own  survey:  • Design  a  clear  survey  question.  If  you  can,  compare  two  different  

groups  (eg:  males/females,  adults/children,  Thailand/USA)  • Collect  data  and  organize  it  clearly  (eg:  tally  chart,  table)  • Clearly  represent  the  data  (eg:  line  plot,  bar  graph)    • Describe  the  data  (eg:  range,  median,  mode,  clusters,  spread,  

outliers)  • Write  a  conclusion  for  your  data.  What  did  you  find  out?
