REQUIREMENTS FOR THE MATHEMATICS ACADEMICS BELT LOOP
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.
REQUIREMENTS FOR THE MATHEMATICS ACADEMICS PIN
Earn the
Mathematics beft loop, and complete one from each of the five areas below:
I.
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. CoBect 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.
II.
Calculating is adding,
subtracting, multiplying, and dividing numbers.
-
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 check out.
-
Visit a bank and have someone there

words and tools: data, averaging, tally marks, bar graph, line graph,
pie chart, and percentage.

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

-
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 ffip it 100 times to find

Interview four adults in different
occupations to see how they use measurement in their jobs.
