2. Content-
|
Multiplying and Dividing Decimals to Thousandths- Common Core: "Perform
operations with multi-digit whole numbers and with decimals to hundredths."
Stars' Distance Relative to the Sun- NGSS: "Space Systems: Stars and
the Solar System." |
| |
|
3. Goals: Aims/Outcomes-
|
1.Students will have developed a deeper understanding of how to
multiply and divide decimals.
2.Students will have developed a deeper understanding of the solar
systems stars' distance relative to the sun. |
| |
|
|
4. Objectives-
|
1.Students will be able to work collaboratively with a partner.
2.Students will be able to visit each planet in a mature and responsible
manner.
3.Students will be able to complete the problems efficiently on their
white boards. |
| |
|
5. Materials and Aids-
|
| Mini white boards, markers, worksheets, planet clue cards |
| |
|
6. Procedures/Methods-
|
|
A. Introduction-
| 1.Explain to students that they will be multiplying and dividing
decimals while working through an activity that is also related to
what they've been learning in science: the stars' distance relative
to the sun. |
| |
|
|
B. Development-
1.Review the solar system stars' distance relative to the sun.
2.Review multiplying and dividing decimals.
3.Explain that for the activity, there would be a solar system for
multiplying decimals and a solar system for dividing decimals.
4.Explain that there are planets taped around the room and that for
the activity, the students have to visit each planet and complete
either the multiplication or division problem that are written on
the planet.
5.Explain that since there are two solar systems, there would be two
of the same planets taped around the room; one planet for multiplying
and the other planet for dividing.
6. Pass out the worksheet and describe to the students how one side
is for multiplying and that the other side is for dividing.
6.Read through the directions and explain to the students that they
will visit each of the planets and work out the problem using mini
white boards.
7.Explain to the students that they would place their answer in the
box (on their worksheet) next to the picture that represented the
planet that they visited. |
| |
|
|
C. Practice-
1.Students will be grouped into pairs and will begin to visit each
planet and therefore, complete the multiplication and division problems.
2.Teacher will walk around the room, making sure the students are
on track. The teacher will answer any questions the students might
have.
|
| |
|
|
D. Independent Practice-
1.The teacher will observe the students working on the problems
to make sure they are completing the problems correctly.
|
| |
|
|
E. Accommodations (Differentiated Instruction)-
1.Students all had the same worksheet. It was expected of the students
that they would work together and help one another.
|
| |
|
|
F. Checking for understanding-
| 1.Teacher will review students' answers on the worksheet to determine
whether they were able to answer the problems correctly. |
| |
|
|
G. Closure-
1.The activity will end, students will pass in their worksheet,
and the teacher will ask students what skills they practiced during
the activity.
2.The teacher can also ask whether they learned anything new/whether
they enjoyed the activity and why. |
| |
|
7. Evaluation-
|
Teacher will review the students' worksheets and develop a score
for each one.
|
| |
|
8. Teacher Reflection-
|
| The students were eager to start the activity and they all seemed
to enjoy visiting each planet. All of the students worked collaboratively
with one another. The majority of the students were able to complete
the problems correctly. Only a couple of the students were having
some difficulties when dividing decimals. All of the students seemed
to be able to multiply decimals with little to no problems. The answers
on the worksheet reflect that the students have developed a true understanding
of how to multiply and divide decimals. However, the errors on the
worksheets were mostly related to the division problems so the students
might need a more direct explanation of how to divide decimals. |
