Specific Expectations 




Collection and Organization of Data 




–
demonstrate an ability to organize objects into categories by sorting and
classifying objects using one attribute (e.g., colour, size), and by
describing informal sorting experiences (e.g., helping to put away groceries)
(Sample problem: Sort a collection of attribute blocks by colour. Resort the
same collection by shape.); 




–
collect and organize primary data (e.g., data collected by the class) that is
categorical (i.e., that can be organized into categories based on qualities
such as colour or hobby), and display the data using onetoone
correspondence, prepared templates of concrete graphs and pictographs (with
titles and labels), and a variety of recording methods (e.g., arranging
objects, placing stickers,
drawing pictures, making tally marks) (Sample problem: Collect and organize
data about the favourite fruit that students in your class like to eat.). 




Data Relationships 




–
read primary data presented in concrete graphs and pictographs, and describe
the data using comparative language (e.g., more students chose summer than
winter as their single favourite season); 




–
pose and answer questions about collected data (Sample problem: What was the
most popular fruit chosen by the students in your class?). 




Probability 




– describe
the likelihood that everyday events will occur, using mathematical language
(i.e., impossible, unlikely, less likely, more likely, certain) (e.g.,“It’s
unlikely that I will win the contest shown on the cereal box.”).
