Presentation of the Lesson The School Library In a school library, there are 576 Mathematics books, 324 English books, 476 Filipino books and 967 other books. - A library They read books and research for their assignments . Books Newspapers and dictionaries. - How many mathematics books are there in the library? - How many were English books? -     1. 2. 3. - Filipino books? - Other books? Here are the number of books again and study  576 mathematics books  476 Filipino books  324 English books  967 other books Since, we have already discussed about Giving the place value of each digit in a 3-digit number. I hope that you have learned to read and write 3digit numbers in symbols and in words and now familiarize yourself to another way of writing numbers. - In 576, how many hundreds are there? - How many tens are there? - How many ones? - And what is the value of 6? The number 576 maybe written in this way: 576= 5 hundreds, 7 tens, 6 ones - It can also be written as: 500+ 70+ 6= 576 Write them in the place value chart. And write them in expanded form. 476 324 967  In writing numbers in expanded form we are expressing the number as the sum of the values of its digit. - In the different examples of numbers we have discussed, what is common among them? - What were the three values taken up? - Does the value affect the - - Hundreds 4 3 9 There are 576 books in the library 324 English books 476 Filipino books 967 other books 500 or 5 hundreds 7 tens or 70 tens 6 ones or 6 Tens 7 2 6 -400+ 70+6 -300+20+4 -900+60+7 - All were three digit numbers - Hundreds, Ones 6 4 7 value of a number? - tens, ones Yes Remember : The expanded form of a number expresses the number as the sum of the values of its digit. It gives the value of D. Learning Activities for Developmental Activities - Group activity Group the class into 4 smaller groups. Each group will be given a different activity sheet. After answering every group will choose a leader and report their work. 1.
