Lesson Plan : Fractional Parts
Teacher Name: | Sherry Howard |
Grade: | Grade 2 |
Subject: | Math |
Topic: | Introduction to Fractions. |
Content: | TEKS - The student is expected to name fractional parts of a whole object when given a concrete representation; and name fractional parts or a set of objects. |
Goals: | By performing this activity, students will become familiar with fractions by relating them to familiar objects. Students will gain a better understanding of fractions and be able to express them with numbers. |
Objectives: | Given a visual object, students will be able to identify and write the fraction of the object that is colored in. They will also be able to name the numerator and denominator in a fraction. After practicing in class, a test will be given to assess the students understanding of the lesson. |
Materials: | Teacher: White paper, colored paper cut in circles. Students: crayons. |
Introduction: | Imagine you had a pizza and you wanted to share it with 8 of your friends. How would you divide the pizza so that everyone got an equal amount? By learning about fractions today you will know how to divide something into equal parts. |
Development: | Teacher holds up peice of white paper and models how to fold it in half and then in half again. Teacher holds up a peice of colored paper cut in a circle and says that it represents a pizza. Teacher then asks someone to hand out peices of white and colored paper. Teacher anounces that students will need to get out their crayons. What is a fraction? (knowlege level) |
Practice: | Students are instructed to fold the white paper in half and then to color one side of the sheet of paper. Students are told to count the total sides of the paper and write that number on the bottom half of the paper. This represents the denominator. (down and denominator start with the same letter) Then they are instructed to count the colored parts of the paper and write that number on the top part of the paper. Teacher instructs the students to get a clean sheet of white paper and do the same procedure only this time folding the paper into fourths. How many parts does the paper have? Identify the two parts of a fraction? (knowlege level) What do you think will happen if we fold the paper again? Can you compare and contrast fourths and eighths.(comprehension level) |
Checking For Understanding: | Have students to use siscors to cut the paper fractions and then reconstruct the whole object. (Analysis level). Draw a picture of 2 other objects you can think of that could be diveded into equal parts, and write the fraction that represents part of the whole object. (Synthesis level). A test will be given to the students with several different objects having fractions shaded in. Students will write the fraction and identify the numerator and denominator with 90% accuracy. |
Closure: | Ask students to explain how the pizza can be divided into 8 equal portions. (Analysis level). |
