Students will learn to collect, categorize, and represent data by using tally marks, tables, pictographs, and bar graphs with intervals of one, five, or ten.  They will interpret the data, including solving addition and subtraction problems.

B.E.S.T. Benchmarks:

• MA.2.DP.1.1 Collect, categorize, and represent data using tally marks, tables, pictographs, or bar graphs. Use appropriate titles, labels, and units.
• MA.2.DP.1.2 Interpret data represented with tally marks, tables, pictographs, or bar graphs including solving addition and subtraction problems.

Key Concepts:

• I can collect, categorize, and represent data using tally marks or tables.
• I can collect, categorize, and represent data using pictographs or bar graphs with scales limited to ones, fives, or tens.
• I can use appropriate titles, labels, and units when I collect, categorize, and represent data.
• I can represent data horizontally and vertically.
• I can interpret data represented with tally marks or tables.
• I can interpret data represented with pictographs or bar graphs with scales limited to ones, fives, or tens.
• I can interpret data to solve problems involving addition and subtraction limited to whole numbers with sums within 100 and related differences.
