Webelos Scouts that earn the Mathematics
Belt Loop while a Webelos Scout
also satisfy requirement 7 for the
Scholar Activity Badge or
requirement 10 or the
Engineer Activity Badge (but not both).
Complete these three requirements:
- Do five activities within your home or school that require the use of
mathematics. Explain to your den how you used everyday math.
- Keep track of the money you earn and spend for three weeks.
- Measure five items using both metric and non-metric measures. Find out
about the history of the metric system of measurement.
loop, and complete
five (one from each of the five areas below)
of the following requirements:
- Geometry is related to measurement but also deals
with objects and positions in space.
- Many objects can be recognized by their distinctive shapes: a tree,
a piece of broccoli, a violin. Collect 12 items that can be recognized,
classified, and labeled by their distinctive shape or outline.
- Select a single shape or figure. Observe the world around you for at
least a week and keep a record of where you see this shape or figure and
how it is used.
- Study geometry in architecture by exploring your neighborhood or
community. Look at different types of buildings-houses, churches,
businesses, etc.-and create a presentation (a set of photographs, a
collage of pictures from newspapers and magazines, a model) that you can
share with your den or pack to show what you have seen and learned about
shapes in architecture.
- Calculating is adding, subtracting, multiplying, and
- Learn how an abacus or slide rule works and teach it to a friend or
to your den or pack.
- Go shopping with an adult and use a calculator to add up how much
the items you buy will cost. See whether your total equals the total at
- Visit a bank and have someone there explain to you about how
interest works. Use the current interest rate and calculate how much
interest different sums of money will earn.
- Statistics is collecting and organizing numerical
information and studying patterns.
- Explain the meaning of these statistical words and tools: data,
averaging, tally marks, bar graph, line graph, pie chart, and
- Conduct an opinion survey through which you collect data to answer a
question, and then show your results with a chart or graph. For
instance: What is the favorite food of the Cub Scouts in your pack
(chart how many like pizza, how many like hamburgers, etc.).
- Study a city newspaper to find as many examples as you can of
- Learn to use a computer spreadsheet.
- Probability helps us know the chance or likelihood of
- Explain to your den how a meteorologist or insurance company (or
someone else) might use the mathematics of probability to predict what
might happen in the future (i.e., the chance that it might rain, or the
chance that someone might be in a car accident).
- Conduct and keep a record of a coin toss probability experiment.
- Guess the probability of your sneaker landing on its bottom, top, or
side, and then flip it 100 times to find out which way it lands. Use
this probability to predict how a friend's sneaker will land.
- Measuring is using a unit to express how long or how
big something is, or how much of it there is.
- Interview four adults in different occupations to see how they use
measurement in their jobs.
- Measure how tall someone is. Have them measure you.
- Measure how you use your time by keeping a diary or log of what you
do for a week. Then make a chart or graph to display how you spend your
- Measure, mix, and cook at least two recipes. Share your snacks with
family, friends, or your den.
