Unit 7 Problem Solving with Length, Money,
and Data Grade 2 Math 


Description: Unit
7 provides another opportunity for students to practice their algorithms and
problemsolving skills with perhaps the most wellknown, interesting units of
all: dollars, dimes, and pennies. Measuring and estimating length is
revisited in this module in the context of units from both the customary
system (e.g., inches and feet) and the metric system (e.g., centimeters and
meters). As they study money and length, students represent data given by
measurement and money data using picture graphs, bar graphs, and line plots.

Enduring Understandings: ·
Measurement
is a way to describe and compare objects or ideas. A specific process is used
to measure attributes. ·
Standard
measurement allows us to communicate with others to describe the physical
world. ·
Measurement
is a consistent duration and distance. ·
The
length of objects can be measured using customary units or Metric units. ·
A
reasonable estimate is one that is close to the actual measurement. ·
Line
plots are useful tools for collecting data because they show the number of
things along a numeric scale. ·
We
collect and use data to help us answer questions and make decisions. 
Essential Questions: ·
What
properties can be measured (length, height, volume, width, area, weight,
time, money and temperature)? ·
How
do we measure (unit, tool, and process)? ·
What
standard units are necessary? ·
How
do we use different types of measurements? ·
What
are tools of measurement and how are they used? ·
When
should you estimate? When do you need an exact answer? What makes a useful
estimate? ·
What
information can we gather from data, charts, and graphs? ·
How
do we conduct a survey? ·
How
can we gather and organize data? ·
How
can represent the data we gather?
