Data Management

Throughout this year the children will have lots of opportunity to explore the data management portion of the curriculum in math.  In Grade One this math strand focuses on sorting, taking surveys to gather information and using graphs to organize and explain the information gathered.  There are all kinds of ways sorting, survey questions and graphs are used in our world and your child would benefit from having these kinds of things pointed out to him/her as you come across them.  Talk to your child about what you see and what kind of information can be learned if you are looking at a graph. Authentic math experiences are always much more meaningful and help connect the learning we are doing at school to the real world.  

Sorting In The Real World:
-the utensil drawer in your kitchen
-how clothes are put away (sorted by colour to wash but then sorted by person who owns the clothes and often sorted again by type of clothing in the room where the person’s bedroom)
-items in a store (all the fresh fruit is in one part of the store, and it is sorted by type)

Ask your child “what would happen if we didn’t use sorting in our world in these situations?”

Surveys In The Real World:
I am constantly bombarded with survey questions:
-each time I buy a new app for my phone or the school iPad they want to know if I want to rate it
-on websites they want to know information about you before you proceed
-telemarketers often call with government surveys about different things
-people stop you in the grocery store with surveys trying to sell their product
-junk mail often arrives with lengthy surveys about products I purchase at the store

Ask your child “why do you think people want to know information about what kinds of products our family uses in our home?”

Graphs In The Real World:
-the weather page in the newspaper, the weather network and the weather app on a phone are filled with graphs 

-travel books and pamphlets often graph the sunny days on a month by month basis
-magazines are full of graphs to give information in an eye catching way

Ask your child “why did the author use a graph to share the information rather than a paragraph of writing?”

Data Management Vocabulary

Here is some of the vocabulary we will be using when engaged in data management experiences.  Using these words regularly in conversation with your child at home will help him/her understand the concepts being taught more clearly.

sort: grouping items together based on at least one similar attribute
survey: a record of observations gathered
graph: a visual representation of data
pictograph:  a graph that uses pictures and symbols to represent information
concrete graph: a graph that uses real objects to represent information
data:  facts or information gathered from a survey
tally: a mark (line) that is used to collect data (a tally counts information by 5’s; four lines with one across the middle representing 5)
many/most/more: greater in amount, how many more?
less/least: smallest in amount, how many less?
few, fewer, fewest:  a smaller number of
equal: the same amount of
