**Represent and interpret data****3.MD.B.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.**Sample Activity:****Represent and Interpret Data **

**3.MD.B.4** Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show data by making a line plot, where the horizontal scale is marked off in appropriate units- whole numbers, halves, or quarters.**Sample Activity:**

**Geometric measurement: understand concepts of area and relate area to multiplication and to addition3.MD.C.5 Recognize area as an attribute of plane figures and understand concepts of area measurement.a. A square with side length 1 unit, called a “unit square”, is said to have “one square unit” of area, and can be used to measure area.Sample Activity:Square Units**

b. A plane figure which can be covered without gaps or overlaps by n unit squares is said to have an area of n square units.

Sample Activities:

Area on the Geoboard

Find the Area (N.B. When printing this activity you may need to specify no page scaling so that the exact size is maintained. Some printers by default print pages at the setting 'Shrink to Fit'. Ensure that your printer is set to print at 100%.)

**3.MD.C.6 **Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).**Sample Activity:**Rectangles with Color Tiles

a. Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths.

Find the Area of a Rectangle

b. Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving real world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning.**Included in** 3rd Grade Math Centers**Word Problems: Area**

c. Use tiling to show in a concrete case that the area of a rectangle with whole-number side lengths a and b + c is the sum of axb and axc. Use area models to represent the distributive property in mathematical reasoning.**Sample Activity:**Jack's Rectangles

d. Recognize area as additive. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real world problems.**Sample Activities:Find Areas of Rectilinear Figures (v. 1)**
