Name: Leah Garrett
Title: Subtraction Day 1
Summary: Students in this class have mastered addition and need to take that step farther and work on subtraction. I will use a visual PowerPoint to show this concept and give the students practice. Then we will move to manipulative and skittle math to continue practicing.
Primary Core Objective: Standard 2 Students will identify and use number patterns and properties to describe and represent mathematical relationships. Objective 2 Recognize and represent mathematical relationships using symbols and use number sentences with operational symbols to solve problems. a.Recognize that "=" indicates that the two sides of an equation are expressions of the same number. b.Recognize that "+" indicates the joining of sets and that "-" indicates the separation of sets. c.Write and solve number sentences from problem situations involving addition and subtraction d. Create problem situations involving addition and subtraction.
Materials Used by the Teacher: Power point presentation Skittles Handouts	Materials Used by the Students: Skittles Handouts Number lines
Technologies Used by the Teacher: Powerpoint presentation	Technologies Used by the Students: Students will help present and answer questions using the projector.
Intended Learning Outcomes: Students will learn that just like you can add two numbers together you can subtract or take some away from another. Students will be able to recognize the - sign and further understand the = sign. Students will be able to create their own subtraction problems.
Instructional Procedures: First I will write some addition problems on the projector and ask for some students to come up and solve the problems. Then after a review I will show on the projector a problem on the overheard using skittles and explain that this is subtraction because I am taking some away. Then I will pull up my powerpoint presentation and go through some more examples of subtraction problems. The powerpoint will put the problems up piece by piece so that they students can really learn about each part of the problem. The last few slides will have the full number sentence pop up with a blank where students will give the answer and it will pop up after the equal sign. When I feel they are comfortable enough with this idea I will give another skittle example or two on the projector and show how they are marking their answers on their worksheet. Then I will pass out their practice sheets and their skittles to use as manipulative.
Extensions: Students on the back of their sheet can write their own subtraction problems on the back using their skittles. Then they will find a partner and they will take turns solving each others problems.
Assessment Plan: Informally I will assess their understanding by how well they are able to participate in the lesson and the answers to the math problems they are providing. Formally I will review the answers on their handout and their own problems they have written to make sure not only is the math right but that they are showing an example of the notation like - signs and = signs.
