Area: the number of square units needed to cover a surface
Perimeter: the distance around a figure
Distance: the amount of space between two given points
Estimate: a guess or rough calculation of worth, quantity, or size
Mass: a measure of how much matter is in an object
Measure: use of standard units to find out size or quantity in regard to length, height, area, mass, volume, time, perimeter
Standard Unit: a traditional unit of measurement from the metric or customary system. (inches, meters, pounds, etc.)
Scaled Bar Graph: a graph that uses bars to show data
Scaled Pictograph: a graph that uses pictures to show data
Volume: the amount of space occupied by an object

Share and discuss tables and graphs found in newspapers and magazines.
Conduct a survey among family members or friends and construct a bar graph or pictograph.
Make a physical pictograph using real objects (e.g., fruits, vegetables, cereal, kitchen tools). Record the graph on paper. Change the scale to create a new pictograph.
Make records of important times of the day (wake-up, dinner, going to school, getting home from school, etc.) and practice telling how long between activities.
Calculate elapsed time by finding out how long it takes to complete daily activities (soccer practice, homework, take a shower, etc.).
Measure the perimeter and area of the rooms in your home to determine which rooms are the smallest and largest.
Use grid paper to make rectangles with the same perimeters. Determine the area of each rectangle.
Fill a small box with blocks (e.g., sugar cubes) to determine its volume. Brainstorm multiple strategies to determine the volume.
