Lesson: Making Amounts Up to 50¢ Using
Pennies, Nickels, Dimes, and Quarters & Think, Pair, and Share
Objectives:
·
Students will realize that starting with the
coin with the largest value possible will mean that fewest coins will be used.
·
Students will be able to substitute smaller
value coins when larger value coins are not available.
Materials:
·
Class set of iPads
· Count Money Free app set to the appropriate level
·
Socrative Student app with a quiz on making
money amounts up to 50¢
·
Interactive white board
Lesson Time: 40 minutes
Procedure:
Before. The teacher sets up the iPad
apps so that the will be working on the right level. He/she sets the number of
problems the students will work through independently during the lesson. On the
day of, he/she sets up the interactive white board and makes sure the touch
screen feature is working.
During. The teacher introduces the class
to the lesson, stating that the class will be practicing how to make money
amounts using pennies, nickels, dimes, and quarters. The class starts out using
the app on the interactive white board first so they can see how it words. Students
make suggestions and the teacher drags the appropriate coins together for the
first problem. Together the class tries an alternate way to make the same
amount. The students then begin to work individually on their iPads. The
teacher circulates to check on students’ progress.
Once the students
have finished their problem sets, students divide into pairs. The teacher poses
a question through the app on the interactive white board and the individual
partners must first think of a way to make that amount separately, then share
their method with their partner. Each group must come up with two ways to make
this amount. Once the groups are
finished, the teacher asks several groups to demonstrate on the interactive
white board how they make the amount. Students explain the strategies they used
and the teacher may interject with questions to guide students toward noticing
patterns (starting with coins with high value means few coins used). Below are
some questions that are useful.
·
Why did you start with this coin?
·
How many coins did X use to make this amount?
·
Could you use more/fewer coins to make this
amount?
·
What if you started with a different coin?
For
each new amount the groups find several ways to make that amount and then share
with the class, offering explanations and demonstrating how to count up to the
amount. Throughout the process the students and teacher ask questions and make
suggestions. As the student become more proficient, the teacher will ask
students to identify the method that requires the few coins, the method that
requires the most, and what methods work when some coins are unavailable.
After. Students return to their
individual iPads to complete a quiz through Socrative. The teacher monitors
each student’s progress through Socrative, checking on students who are taking
longer than others and analyzing the results. Kids Coin Fun will be available
for students to use over the next few weeks.
