GIVEN UNIT/TOPIC:

            Mathematics

GRADE LEVEL:

            Second grade

LESSON TOPIC:

            Single and multi-digit subtraction

LESSON OBJECTIVES:

• The students will be able to correctly answer subtraction problems.
• The students will show all of their work on another sheet of paper to show their thinking and understanding of the subtraction process.

INSTRUCTIONAL TECHNIQUE:

•       A review of subtraction will take place before the students go onto the website
•    The students will get with a partner and begin to work on the computers
•       The students will work together on the problems by taking turns writing their subtraction process on the separate sheet.
•       The students will check their work with the website. If the answer is incorrect then they must try again by rewriting the problem on the paper and resolving.
•      The students will stop after level 3 of the game.

INSTRUCTIONAL MATERIALS:

• Computers (http://www.abcya.com/subtraction_game.htm)
• Handout
• Paper/pencils

THEORETICAL PERSPECTIVE:

It is important for the students to be confident with basic subtraction problems so they can move onto more complex problem solving. Subtraction is just the beginning of different mathematical processes that students must know. Students must know how to do subtraction problems for everyday life as well both at their age now and when they grow up.

PROCEDURE:

1. Intro: The teacher will have a review session of single and multi-digit subtraction problems. Students will write down notes to refer to while completing the lesson.
2. Step By Step:

i)        The teacher will pair the students into groups of two for the students to work on the computers.

ii)      The students will meet with their partners and grab one computer.

iii)    The teacher will give each set of partner’s one handout with the instructions of what to do for the lesson as well as loose paper to solve the subtraction problems on.

iv)    The teacher will read through the instructions and answer any questions that the students may have.

v)      The students log onto the computers and make their way to the given website.

vi)    The students will take turns writing the problems on the loose paper to solve them. (However the students will be working together to solve each problem.)

vii)   The students must show all work on their paper.

viii)            After completing the problem on the paper, the students will check their work on the website. *If students get the problem incorrect they must rewrite the problem on the paper and solve again. They must rewrite it so the teacher can see how many attempts it took for the students to get the problems correct.*

ix)    After completing the assignment the students will turn in all of their work into the teacher.

3. Closure: To end the lesson, the teacher will look at the students work to see which problems multiple students got incorrect and review them with the entire class.
4. Adaptation for Different Leaners: If there are ELL students the class, the teacher will have them work with the ESL teacher for this lesson. Students who struggle with math will have the option to work with the teacher in a small group and each will write the work out to work on their understanding or the students can work with a student who is more advanced in math so they can answer questions they may have. If the students choose to work with another student then the struggling student still must show their work separately from their partner.

EVALUATION:

1. Objective: The students will be able to correctly answer subtraction problems.

Demo: The teacher will determine if the students meet this objective by checking over their work that they wrote down on their separate sheet of paper. The teacher will also be walking around during the lesson to check on students and their work.

Objective: The students will show all of their work on another sheet of paper to show their thinking and understanding of the subtraction process.

Demo: The teacher will be able to document the student’s success of this objective by collecting the students work from the lesson.

B.     There are two concerns I have with teaching this lesson. I am concerned that the students will not write down all of their work, especially for the easier problems. I am also concerned that the students will click the balloons at random without even trying the problem until they get it correct and then they will just write the correct answer down on their own sheet.
