| The Divisibility Rules for 2, 5, and 10 |
| |
|
3. Goals: Aims/Outcomes-
|
1.Students will be able to tell the difference between an even and
odd number.
2. Students will be able to repeat the basic rules of divisibility
for 2, 5, and 10. |
| |
|
|
4. Objectives-
|
1. Students will be able to complete the 3 worksheets given to them
classifying whether the individual numbers are divisible by the one
given.
2. Students will be able to effectively name some real life examples
of how the divisibility rules for 2, 5, and 10 could be useful. |

|
5. Materials and Aids-
|
1. Computer for PowerPoint
2. 3 worksheets per child, provided by Teacher.
3. Pencil
4. Package of candies as covers for their worksheets.
5. Rules of Divisibility printout. |

6. Procedures/Methods-

A. Introduction-
(Anticipatory Set)
1. The teacher will begin the lesson by asking the students if they
like to take "shortcuts" with things in life. Prompt responses by
asking if they ever "cut off the corner of the street, to get to their
friends how quicker?" Once responses have generated interest in the
children, ask them if they knew that there are shortcuts to learning
division! And if not, we're about to learn them. |

B. Development-
1. The teacher begins the lesson by putting a PowerPoint onto the
overhead computer and begins to read the slides.
2. By slide 3, it asks the audience a question on if they could divide
this large number, by other smaller one digit numbers, regaining their
focus onto the task up ahead.
3. By the 9th slide, the children have been involved with the questions
on the PowerPoint and in their "divisibility packets," there is a
copy of slide #9, asking whether a few of these numbers are divisible
by 2, 5, 10. These will be done mainly by the teacher with the help
of voiced opinions from the students.

C. Practice-
1. Once the teacher has finished the last slide of the PowerPoint,
where it gives the children their take-home assignment, the teacher
will have them pull out their "divisibility packets" and turn to the
3rd page. They will work with their partners at their tables and read
the instructions and complete the task at hand.
2. The children will follow the same instructions for the worksheets
of divisibility by 5, and 10 as well.
(Check for Understanding) The teacher will walk around the room, checking
to make sure all students are understanding the concept of the divisibility
rules, checking their answers and listening to their debates of whether
a certain number is divisible by another.

|
|
D. Independent Practice-
1. The children will be asked to go home and find examples of how
they could apply the divisibility rules to their everyday lives.
2. They will also complete and turn in their worksheets on divisibility
of 2, 5, and 10.
3. Begin preparing themselves for the next days task of learning two
more divisibility rules, for the numbers 3, and 9! |

E. Accommodations (Differentiated Instruction)-
1. For children with special needs, we will partner them up with
one of the more helpful students to give them a better chance of understanding.
2. The children of specific disabilities will be given less numbers
to associate divisibility rules with.
|
| |
|
|
F. Checking for understanding-
Once back in class the following day, the teacher will take up their
"Real World of Divisibility" examples and evaluate how well they learned
these three rules by discussing them again before the next lesson
begins.

|
Teacher Reflection-
|
| Thought we had a great lesson and activity today and thought the
children related well to the examples of divisibility in the real
world. They understood why it was important to be able to quickly
evaluate if 3884 could be divisible by 2, just by looking at the units
digit. They know that it can come in handy from separating snacks
with your friends to planning where children will sit on their way
to a classroom field trip, even separating children to play certain
sports on the playgrounds! Everyday you can find a new example of
why knowing these rules make you and everyone around you, lives easier! |
