Final Project Lesson Plan

7 December 2011

Unit Topic: Adding and Subtracting Decimals

Grade: 4

Lesson Topic/Theme: Adding and Subtracting Monetary Amounts

Lesson Objectives:

Students will be able to interpret and solve word problems accurately.

Students will be able to add and subtract decimals as it pertains to money.

Students will be able to answer the word problems from the website correctly when provided with scratch paper.

Instructional Technique:

            During one class period, students will log onto the website and play through the questions.  They will be provided with scratch paper and a sheet on which to fill out correct answers as proof they finished the game and got the right answers.

Instructional Materials:

            Computers

            Scratch paper

            Answer sheet (attached)

Theoretical Perspective: It is important for students to understand the concepts of adding and subtracting money because it is a skill they will need for their future. Also this activity helps students to recognize the importance of charity and donations and how they can help others who are less fortunate. 

Procedure:

Introductory Activities with learning the different types of money and coins, including adding and subtracting different values using money and decimals.

Step-by-step

First we will cover the basics of currency and how it is involved with mathematics. This will include covering what kind of bills and coins there are and working with adding and subtracting decimals.

We will then do multiple problems with students in the classroom, until a general understanding of adding and subtracting with money has been met by all students.

We will then incorporate word problems into the lesson and prepare students again for their interactive computer game!

On the day we use the interactive website, students will be handed out their answer sheets and given a computer to work on.

Students will then be responsible for answering each question and finding the correct answers using their answer sheets to show their work and final answers on.

We will close the entire lesson with a class discussion asking students what they have learned about addition and subtraction with money and how they enjoyed working on the computers. This should give us enough feedback so that we can alter any problems within the original lesson.

Adaptations: Learners who have problems with reading or mathematics will be able to work with a partner. Teachers will also always be available for any extra help students may need if they do not understand the problems.

Evaluation:

Objectives:

Students will be able to interpret and solve word problems accurately.

            - This can be shown by the amount of students who may raise their hands for help on questions. The less questions they have, then we will know that they understand their word problems.

Students will be able to add and subtract decimals as it pertains to money.

            - This can be shown by the accuracy of answers students provide on their given answer sheets.

Students will be able to answer the word problems from the website correctly when provided with scratch paper.

            - We can observe students while they work on the interactive website, and our best results could be that all students are using their scrap paper to work out the problems.

Concerns/Questions

            - Our only concerns with this lesson plan are that students will struggle with the decimal placement or the wording of some of the word problems.
