LAC 28:CXLII.509. Data Analysis and Measurement

A. Measure lengths indirectly and by iterating length units. 1. Apply knowledge of “longer than” and “shorter than.” a. Order three objects by length. b. Compare the lengths of two objects indirectly by using a third object. 2. Express the length of an object as a whole number of length units by laying multiple copies of a shorter object (the length unit) end to end. a. Understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. B. Tell and write time. 1. Tell, write, and represent time in hours and half-hours using analog and digital clocks. C. Represent and interpret data. 1. Use tally marks and t-charts/tables with up to three categories. a. Create bar graphs and/or picture graphs to represent data precisely with accurate scaling within a scale of 1 or 2; and b. Interpret data represented in a chart or graph by asking and answering questions about the total number of data points, how many in each category, and how many more or less are in one category than in another. D. Work with money. 1. Determine the value of a collection of coins up to 50 cents. Pennies, nickels, dimes, and quarters in isolation; not to include a combination of different coins.
