4.01 Collect and organize data as a group activity Display and describe data with concrete and pictorial graphs as a group activity. Mathematics Curriculum Grade K

4.01 Collect, organize, describe and display data using line plots and tallies Describe events as certain, impossible, more likely or less likely to occur. Mathematics Curriculum Grade 1

4.01 Collect, organize, describe and display data using Venn diagrams (three sets) and pictographs where symbols represent multiple units (2's, 5's, 10's) Conduct simple probability experiments; describe the results and make predictions. Mathematics Curriculum Grade 2

Mathematics Curriculum Grade Collect, organize, analyze, and display data (including circle graphs and tables) to solve problems Determine the number of permutations and combinations of up to three items Solve probability problems using permutations and combinations.

Mathematics Curriculum-Grade Collect, organize, analyze, and display data (including line graphs and bar graphs) to solve problems Describe the distribution of data using median, range and mode Solve problems by comparing two sets of related data Design experiments and list all possible outcomes and probabilities for an event.

Mathematics Curriculum Grade Collect, organize, analyze, and display data (including stem-and-leaf plots) to solve problems Compare and contrast different representations of the same data; discuss the effectiveness of each representation Solve problems with data from a single set or multiple sets of data using median, range, and mode.
