4th Grade Lesson Plan for Expanded Notation

4th Grade Lesson Plan for Expanded Notation Students will create, read, and decompose large numbers. Class 4th Grade Duration One or two class periods, 45 minutes each Materials: paper or large note cards numbered 0 - 10 (enough for the whole class)chalkboard, whiteboard, or overhead projector Key Vocabulary place value, ones, tens, hundreds, thousands, ten thousands, hundred thousands, expanded notation (or expanded form) Objectives Students will demonstrate their understanding of place value to create and read large numbers. Standards Met 4.NBT.2 Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Lesson Introduction Ask a few volunteer students to come to the board and write down the largest number that they can think of and read aloud. Many students will want to put endless numerals on the board, but being able to read the number aloud is a more difficult task! Step-by Step Procedure: Give each student a sheet of paper or large note card with a numeral between 0 - 10.Call two students up to the front of the class. Any two students will work as long as they are not both holding a 0 card.Have them show their numerals to the class. For example, one student is holding a 1 and the other is holding a 7. Ask the class, â€Å"What number do they make when they stand next to each other?† Depending on where they are standing, the new number is 17 or 71. Have students tell you what the numbers mean. For example, with 17, the 7 means 7 ones, and the 1 is really 10.Repeat this process with several other students until you are confident that at least half of the class has mastered the two-digit numbers.Move on to three digit numbers by inviting three students to come to the front of the class. Let’s say that their number is 429. As in the above examples, ask the following questions:What does the 9 mean?What does the 2 mean?What does the 4 mean?As students answer t hese questions, write the numbers down: 9 20 400 429. Tell them that this is called â€Å"expanded notation† or expanded form. The term â€Å"expanded† should make sense to many students because we are taking a number and expanding it into its parts. After doing a few examples at the front of the class, have the students begin writing the expanded notation down as you invite students up to the board. With enough examples on their paper, when it comes to more complex problems, they will be able to use their notes as a reference.Continue adding students to the front of the class until you are working on four-digit numbers, then five-digit, then six. As you move into the thousands, you may want to become the comma that separates thousands and the hundreds, or you can assign the comma to a student. (The student that is always wanting to participate is a good one to assign this to - the comma will be called upon often!) Homework/Assessment You can give your students a choice of assignments  - both are equally long and equally difficult, though in different ways: Have students write 987,654 in expanded notation OR the largest number that they are able to.Have them write 20,006 in expanded notation (Be sure to go over this one in class the next day.) Evaluation Write the following numbers on the board and have students write them in expanded notation:1,78630,551516

Free Essays on Ordinary People

The book I did my report on is called Ordinary People, by Judith Guest. It is a very well written novel about a boy’s battle with depression, suicide, the loss of his brother, and communication gaps with his parents. The story starts by not telling you much about the situation, and the more the book ropes you in. The boy in the story starts out being 17, his name in Conrad Jarrett. Conrad had an older brother who died in a boating accident, he drowned. Conrad idolized his older brother, and never really came to terms with the loss, and about 1 year later, Conrad tried to take his own life. After that, his parents sent him to a hospital for the depressed, he spent 8 months there, and fell a year behind in school, and grew apart from his friends. This story starts when he is back in school and repeating his Jr. year. Throughout the story you see his ups and downs and recovery. Also, one of his main problems is communicating with his parents. His father feels tremendous guilt and just constantly tries to make him happy, but his mother on the other hand, resents him for trying t take his own life. In the end Conrad finally comes to terms with his loses, and faces his problems head on. He regains the friendships that, in his mind are worth it, and lets go of the ones that really weren’t. Conrad is the main character in this story. Throughout the story he undergoes many changes, good and bad. At first he goes through many low points, where he feels he has nothing, no friends no family, and no one to rely on. Until he finds a psychiatrist named Dr. Tyrone C. Berger. Mr. Berger helps Conrad to come to terms with his problems and face them. Conrad doesn’t develop any close relationships with anyone throughout the story until Berger comes along. Then he becomes involved with a girl named Jeannie. He develops a good relationship with her, and they are still going out at the end of the story. I think Conrad is a good kid that just tries t... Free Essays on Ordinary People Free Essays on Ordinary People What exactly makes a world and it’s people ordinary? In the spellbinding novel Ordinary People, Judith Guest gives readers a taste of life after having to deal with a terrible crisis, and introduces us to an ordinary family living in an ordinary world. The novel’s descriptive nature highlights the main character, Conrad’s, struggle in maintaining sanity in an ordinary world. Conrad Jarrett is a precise description of a teenager, having to deal with things every teenager his age has to go through daily. The internal conflicts he struggles with, especially his need for affection, and his sense of wanting to belong is what deepens the plot and intrigues readers even more. We see conrad’s point of view on life, of the world in which he lives, and where he sees himself fitting into. "†¦.Your sense of identity is what seems to have been misplaced. No. Wrong. You don’t lose what you never had." (pg.24) Readers can take his point of view and compare it with their own observations. The next issue is that the affection he is searching for, he gets from the wrong person, his father, while he really needs it from his mother. "†¦.She loves my father, I know that. She loved my brother, too. It’s just me."(pg.188). Trying to get his mother’s affection and approval is what in some ways intensifies his struggle, as well as affects h is parent’s marriage. The descriptions Judith Guest gives throughout the story, regarding all the different issues, that come up, make the book even more realistic, and in some instances even humorous. The descriptions given, depend of Conrad’s mood at that time. Although it may seem like it is a bad thing it’s not! The variety in the descriptions (which resemble his moods), add excitement to the novel, and make the story flow a lot better. The reader will know what to expect from a chapter, just from the descriptions given at that moment. For example, will it be humorous? Depressing? Touching? ...
