math questions units 1 & 2
TRANSCRIPT
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?
