 
Mathematics Lesson Plans
Introduction to scales and map interpretation
 Interpreting pictures and scale 
 Working with ratios 
 Building a map of a known location 
 Calculating areas and perimeters of invaded marsh
(different shaped objects) 
 Calculating rates of expansion from measured data 
How fast is the
invasion?
 Using mapping
and scale to solve real world problems 
 Using measurements of
distance and time to calculate rates 
 Extrapolating
from an existing set of data to predict future trends. 
 Calculating
areas of regular shapes (rectangle, oval) in order to solve real world
problems 
 Calculating
percent in the context of a real world problem 
 Use of
critical thinking skills to assess patterns observed within a data
set 
Quadrat sampling
 Collecting data on species diversity and abundance in
a map of a series of model marshes 
 Working with averages (mean, mode, median), range and
percentages 
 Creating meaning for mathematical ideas like density
and rates 
Effective Graphing
Part 1 and Part 2
 Reviewing which graph to use in what context and why 
 Reviewing independent and dependent variables

 Applying this to determining which variable is X
versus Y 
 Assessing whether a variable is continuous or
discrete 
 Graphing data collected in previous day's classes
(rates, diversity, abundance, relationships)
Pie
charts
Bar
charts
Scatter plots
