Grade 2 – MathematicsCurrent TEKS: Probability and Statistics Revised TEKS (2012) Supporting Information Notes2(11)(A) Probability and statistics.The student organizes data to make it usefulfor interpreting information.2(10)(B) Data analysis. The student appliesmathematical process standards to organizedata to make it useful for interpretinginformation and solving problems.The student is expected to organize acollection of data with up to fourcategories using pictographs and bargraphs with intervals of oneor more.The number of categories has been constrainedto four.Intervals may be one or more.+The student is expected to constructpicture graphs and bar-type graphs.2(11)(B) Probability and statistics.The student organizes data to make it usefulfor interpreting information.The student is expected to drawconclusions and answer questions basedon picture graphs and bar-type graphs.2(11)(C) Probability and statistics.The student organizes data to make it usefulfor interpreting information.2(10)(A) Data analysis. The student appliesmathematical process standards to organizedata to make it useful for interpretinginformation and solving problems.The student is expected to explain that thelength of a bar in a bar graph or thenumber of pictures in a pictographrepresents the number of data points for agiven category.2(10)(D) Data analysis. The student appliesmathematical process standards to organizedata to make it useful for interpretinginformation and solving problems.The student is expected to drawconclusions and make predictions frominformation in a graph.2(10)(C) Data analysis. The student appliesmathematical process standards to organizedata to make it useful for interpretinginformation and solving problems.The student is expected to write and solveone-step word problems involving additionor subtraction using data representedwithin pictographs and bar graphs withintervals of one.Specificity has been added in how students areexpected to be able to explain theirconstruction of a picture graph (pictograph) ora bar-type graph (bar graph).Specificity has been added regarding the typesof questions. The questions for this SE willfocus on making predictions.Pairing this SE with revised SEs 2(10)(A) and2(10)(B)shows that the graphs are pictographsand bar graphs.Specificity has been added regarding the typesof questions students are expected to answer.Specificity has been added regarding intervalson the graphs.Students are now expected to write problemsinvolving addition or subtraction using datarepresented within the stated graphs.–The student is expected to use data todescribe events as more likely or lesslikely such as drawing a certain colorcrayon from a bag of seven red crayonsand three green crayons.This skill is not included within the RevisedTEKS (2012).©2013 Texas Education Agency.
