Unit 3: Annotated Lesson Plan National University TED 621A November 13, 2013 Unit 3: Annotated Lesson Plan I. Lesson Description Date: November 13, 2013 Content Area: Math Topic: Percents, Fractions, Decimals Title: Relate Percents to Fractions and Decimals Grade: Fifth Makeup of classroom: 18 students, nine boys, and nine girls. Two ESL students, one from Mexico and one from Russia. Both students are classified as higher end, they have been here for a couple of years and understand most concepts. II. Goal and Objectives Goals: The goal of this lesson is to have students interpret percents as part of a hundred. Also to find decimal and percent equivalents for common fractions and explain how to change a fraction into…show more content…
First the teacher will explain to the students the definition of percent. Percent means per 100. Percent compares a number to 100. The symbol is %. Next, the teacher will hand out the math notes, so the students can follow along. Having math notes that students can keep in a binder and refer back to is real helpful in math. Next the teacher will ask the students to think about how many problems are on their normal math test, this number will be the bottom of the fraction. Then the teacher will ask the students for a number to put in the numerator place. Now that we have a fraction the teacher will show them how to find the percent by making an equivalent fraction. The equivalent fraction MUST have a denominator of 100, since percent means per hundred and they are comparing the number to 100. Next the teacher will review how to make an equivalent fraction. By multiplying the bottom of the fraction by 5, you will get the new denominator to be 100. If you multiply the bottom of the fraction by 5, then you need to multiply the top of the fraction by 5. Your new fraction will be 75/100. The teacher will then remind the students that percent means per 100, so if the bottom of your fraction says 100, then your percent is the numerator. If students do not have a denominator of 100 then they will not have the…show more content…
To change this denominator to 100 you will have to divide by 10 and if you divide the denominator by 10 then you will have to divide the numerator by 10. Example: Denominator 1000 divided by 10 = 100 Numerator 375 divided by 10 = 37.5 Your new fraction will be 37.5/100 The last step will be to write your fraction as a percent. Example: Since your denominator is 100 your percent will be 37.5%. Activity 2 The teacher will go over a few more problems on the board with the students following along and asking questions along the way. Once the teacher feels the students have a grasp on the concept the teacher will realease the students to work on some of their problems in the book. This is not a group assignment and students should work on the problems themselves. V. Reflective Assessment and Evaluation Asessment: Students will work on preselected problems out of the book while the teacher and instructional aide walk around and make sure they are on task. At this time students may ask for help if needed. If there is several questions on the same problems it’s a good idea if the teacher gets the attention of the class and works that problem on the board with the students following
