Unit Topic: Math

Grade: 1

Lesson Topic: Addition

Lesson Objectives: The Student will be able to answer correctly 8 out of the 10 addition problems on the worksheet with or without the use of base 10 blocks.

Instructional Technique: Lecture, online activity, worksheet.

Instructional Materials: http://www.sheppardsoftware.com/mathgames/popup/popup_math_addition.swf

Base 10 blocks, Instructional sheet, worksheet

Theoretical Perspective: Everyone needs to know how to add.  We add every day, such as when spending money in a store.  If you buy a couple items from a store, you need to know how to add up the prices of those items in order to make sure you are getting charged the correct price!

Procedure:

Introductory Activity: Start by having the students sit in groups of 2-3 at tables.  The teacher will lecture the students on how to use base 10 blocks when adding.  Once the lecture is over, write two addition problems on the board, and have the students solve these two problems in groups using the base 10 blocks.  Go over the answers once students have completed the two problems.

 Step-By-Step: To further improve the students addition skills, have them go to http://www.sheppardsoftware.com/mathgames/popup/popup_math_addition.swf and have them follow the directions and answer the addition problems on the website.  While solving the addition problems online, make sure they are following all instructions and filling in all areas of the instructional sheet. 

            Whichever addition problems the student got wrong on the website, have the student try to answer the problem again, but this time using the base 10 blocks to help solve the problem. 

            At the end of class, have each student individually complete a worksheet with ten addition problems.  While solving the problems on this worksheet, the students can use base 10 blocks if they feel more comfortable using them.

Closure: Ask the students if they found it easier to add with or without the base 10 blocks.  Ask the students if they have any questions. 

Adaptations for different learners: To plan for learner variability, the students have the option of using the base 10 blocks for the worksheet.  Everyone has strengths and weaknesses.  Some students may be better visual learners, and may benefit from the use of base 10 blocks, while others may learn more effectively without the use of base 10 blocks. 

Evaluation:

Our objective was “The student will be able to answer correctly 8 out of the 10 addition problems on the worksheet.”  We will find out if our students met the objective once we grade the worksheet.  The worksheet will be graded during our prep period or at home.

One concern we have about teaching this lesson is the student forgetting to write an “x” next to the problem they got wrong on the website.  We just have to make sure we clarify that they write an “x” right next to a problem that they got incorrect.
