Abstract
Students will find the effectiveness and usefulness of using
decimals, fractions, and percents in our lives.
Lesson fundamental understandings:
Essential
Questions: How would your daily life be different if
we did not have decimals, fractions or percents?
Standards
National Standards Number and Operations
Compare and order fractions, decimals, and percnets efficiently
using approximate locations on a number line.
State Standards Nevada Mathematics
content Standards and Indicators of Progress- Grade 7 1.7.6 Compare
and order groups containing a mix of fractions, percents, and
decimals (e.g., on a number line)
Lesson
Prerequisite Skills
Students will have prior knowledge of how to work with fractions,
decimals, and percents in daily life.
Teacher
Information/Situations/Setting/Time Ask, “How would
your daily life be different if we did not have decimals, fractions
or percents?”
Lead a short discussion on fractions, decimals
and percents. Briefly cover the use of these number representations
in daily life.
After initial discussion, students will write
a paper to explain differences and give reasoning.
After the
writing process is complete, the class will discuss if a new number
system would be created.
The teacher will decide whether
students will work on this activity individually or in
groups.
Setting/ Time
This lesson will take one 90-minute
or two 45 minute periods.
Assessment
Assessment will be continuous through out the lesson based on
questioning, discussions and modeling.
Papers would be graded
according to a rubric based on differences created with examples of
those differences.
Student Activity/Tasks -Students will
discuss as a class what fractions, decimals, and percents are and
how they are used in daily life.
- Students will discuss as a
class or small group the life difference example.
- Students will
share their methods and process of reaching the solution.
-
Teacher will monitor student progress and guide as needed.
-
Teacher will help students as necessary.
- Students will
demonstrate and explain possible solutions. Class will discuss
possible methods.
- Students will explain logic.
Enrichment/Alternate Activity:
Research might be done on how fractions, decimals, percents were
dealt with in early civilizations.
Cross-Curricular:
Social Studies- Early civilizations had number systems, but not
based with numbers less than zero. Students will discover how these
were used.
Technology
Requirements/Tools/Materials
Websites will be used to research early civilizations as well as
when fractions, decimals, percents were introduced into
life.
