Math Q4 Review

• I can draw scaled graphs (picture and bar) to represent a data set.

• I can compare the perimeter of polygons.

• I can compare the area of polygons.

• I can solve word problems involving perimeter and area of rectangular figures.

We can recognize data in a tally chart or frequency table.

• A picture graph uses different pictures to display or show data.

  Usually the picture is a representative of what you are tallying.

• A pictograph, or scaled picture graph, uses one picture or symbol

  to represent more than one tally. A key is needed to show what

  each symbol represents.

A bar graph shows data using bars that are different lengths or heights. You read a bar graph by finding the number that represents the length or height of each bar.

• The perimeter is the distance around the outside of a figure or shape.

• To find perimeter, add the lengths of the sides.

The number of square units needed to cover a figure without overlapping is called area.
