OBJECTIVES:
1)  Given the White Sox averages, compute the batting averages
and earned run averages.
2)  Given general dimensions of the playing field and some
equipment, change to the metric system.
3)  To find the diagonal distance from 3rd base to 1st base.
4)  To find the diagonal distance from 40 ft behind 3rd base
to 1st base.

MATERIALS:
2)  prepared transparencies
3)  White Sox  average sheet from the Chicago Sun-Times (7-16-86)
4)  picture of a baseball field
5)  blackboard
6)  baseball
7)  bat
8)  calculators
9)  an official baseball rules handbook

STRATEGIES:
Does anyone know the nation's oldest active major league ballpark?
Comiskey Park

Fine-----Let's Play Ball
The league President appoints an official statistician to maintain an accumulative
record of all the batting, fielding, running, and pitch-ing records for each
player. This morning we are going to complete an abbreviated average table.  This
table was obtained from Wednesday's Sun-Times--July 16, 1986. (Figure 2)

Batting averages  =Hits  The percentage of times that a player gets
A.B.    a hit.

The headings for each column will be explained. The formula will be emphasized and
the students will now compute the batting averages of the names listed on their
table.

Earned Run Averages = (ER/IP)9  The average number of runs a pitcher
allows his opponents to score.

The headings for each column will be explained. The formula will be emphasized and
the students will now compute the earned run averages.

Certain dimensions are given of the playing field and equipment.
(Figure 3) Change standard units to the metric system.

Using the baseball field:  Find the distance from 3rd base  to 1st.
Draw the distance. Compute.
Pythagorean Theorem       OR                  45-45-90 Rt Triangle
d2 = 902 + 902                                Leg times the sq rt of 2
d = 127.28 ft.                                d = 127.28 ft.

The left fielder catches a bouncing ball 40 ft.
behind the 3rd base. How far would the out-
fielder have to throw the ball.  Draw the
distance. Compute
Pythagorean Theorem
d2 = 1302 + 902
d = 158.11 ft.

BRAINTEASER
There are 100 seats available at the baseball game. These seats may be divided in
proportion to men, women, and children.  However, the cost of the tickets for
these seats must equal exactly \$100. The cost for a man is \$5.00, for a woman
\$2.00, and for a child \$.10.  Determine the number of men's, women's, and
children's ticket to purchase.
