5-Division

1-Excellent pupils
A school distributed 56 books among 4 pupils who won the excellent pupils contest. How many books did each pupil take?
Complete:
    The number 56=5tens and .........units
    5 tens4=....ten and....tenis left
    Then, 164=.....So, each of the winners took ....books
    This could be witten as follows



p.16
and discusseing them about the solution of the example in this page.

56 4 number 56=5tens and 6 units
5 tens 4=1 ten and 1ten remainde, i.e. units becam 16 units
16 units4=4units

Then, 564=14, we can write this as follows:





And discusses with hem in the sam method the solution of the question number (1) page (18).



In grade 3 pupils studied dividing any number by 1-digit number, but in this lesson they learn how they divide any number by 2-digit number.
Time:4 periods Place: classroom
Instructional materials: blakbord, colore chalk, textbook, workbook.


*The goal of the lesson:

In the end of this lesson we rxpect that pupils will be able to do the following:

1-Dividing by 2-digit number easily.
2-Using division processe to solve arthmatic problems, which in need in to this.


*Steps of the lesson


*Modification:

-We give students some problems to divid any number by 1-digit number, for exampel 5055 and explaining division processe.
5 hundreds is divided by 5=1hundred
0 tens is divided by 5=0 tens
5units is divided by 5=1unit
So, it is:
505 5=101
, 1263
12 tens is divided by 3=4 tens
6 units is divided by 3=2 units
So, it is 1263=42

*Showing lesson: -Teacher asking the pupils to open textbook page(16),
page(21)



876618=487418623=182
744024=310798749=163
841545=187191191=21
And in the following prolems number:4,5,6,7,8 page(19) there are word problems of the life situations , the teacher must make sure that the puiples know the kind of the used process and the teasons of using , (It is noticed that puiples use division processe).
-Question number (4) page (19):
Number of floors in the hotel=20412=17
-Question number (5) page (19)It is better for the teacher when he discusses the solution ofthe problem mentioning to the pupils some touristic places in Egypt and the nesessary of tourism in Egypt, because it is very importand source of the national income.

76 tens is divided by 15 =5 tens and 1 ten remaind, 15 units is divided by 15-1 unit.
Then, 765 15=51
Then leave the pupils to solve the other parts of a question 1, and teacher follow up solutions of pupils, and corecting the mistakes at the same time.
and the right solutions of some parts of this question (1)are:
page(22)



*What the number which if multiply in 4 tens then the product is 108 tens?
Solution=27.
Then complet the division processe normal.

Too, this problem help you to confirmed of evaluation the goals of this lesson.
too,there are some word problems uding student to aplecation about what you learned in this unit in life stuation.and must be ateacher confirmed to knowing student type of processe.

_Question number (2) page (28) in the workbook part 3.
-Discusse pupils by giving them the following questions:
