Livingston County Schools 3rd Grade Math Unit 2 Graphing/Using Linear Measurement Unit Overview Students demonstrate an understanding of measurement by justifying how to use tools to measure to the halves and fourths of an inch. Students analyze and construct data using line plots and graphs. Students problem solve using properties of operations. Students add and subtract whole numbers within 1,000. Students will understand quantities of fractions. Length of unit: 3 weeks KY Core Academic Standard 3.MD.3 Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one and two-step “how many more” and “how many less” problems using information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets. Learning Target K I can identify the parts of a graph (scale, data, title, labels, categories.) X I can explain the scale of a graph with a scale greater than one. X R S P Critical Vocabulary Scale Scaled Graph (bar/picture) Title I can analyze a graph with a scale greater than one. X I can interpret a bar/picture graph to solve one or two step problems asking “how many more” and “how many less.” X Label “how many more” and “how many less” (signal subtraction) data I can choose a proper scale for a bar graph or picture graph. I can draw a scaled picture graph to show data. X X Texts/Resources/Activities Coach Book Math book Brain Pop Jr. Graph paper Study Island Discovery Education I can draw a scaled bar graph to show data. Spiraled Standards: 3.NBT.2 3.OA.1 3.OA.7 3.NF.1 3.NF.2 X HOT Questions: 3.MD.3 – After completing a survey about favorite animals, colors, toys, etc. and completing a tally chart, Draw a bar graph to represent the results of your data. 3.MD.4 – Create a line plot where the horizontal scale in marked off in appropriate units ( whole numbers, halves, quarters, etc.).
