Introduction (Focus Involve Transfer)
Discuss with students
¨ Addition is putting numbers together to find out how many.
¨ Finding out how many is called finding the sum.
¨ The (+) is called a plus sign. In a math problem, this means you add.
Instruction (Guided Practice, Procedures.)
Addition with manipulatives
¨ Give each student or pair of students a bag of manipulatives.
¨ Let them play with the manipulatives a minute or so before starting. (They will anyway.)
¨ Get students to count out a pile of five manipulatives. Put the others aside.
¨ Get them to count out a pile of two manipulatives, and a pile of 3 manipulatives from the pile of five. How many manipulatives are in each pile? How many altogether?
¨ Get students to practice this activity for all possible sums of five.
¨ Get students to practice this activity for all sums you wish to teach.
(Don't forget to practice 5+ 0 etc.)
Addition with paper and pencil.
¨ Copy a portion of the worksheet in suggestions
¨ Get each student to solve the problems on the work sheet.
¨ See directions in suggestions.
Summary Closure
¨ Get students to practice in pairs with flash cards.
¨ See suggestions for making flash cards.
¨ If you have skill and practice computer games, this is a good time to use them
Assignments (Independent Practice, Homework)
¨ Get students to take home work sheets and practice.
¨ Get the to practice with flash cards
Suggestions
Manipulatives. I like to use dried beans for this activity.
Fingers also make great manipulatives.
Fingers are probably the best manipulative for using if you are using manipulatives and work sheets at the same time.
Be aware that in some places "counting on fingers" has been traditionally frowned upon.
Worksheets. AVOID THEM IF PRACTICAL. Use the chalkboard instead.
This gives your students more practice in writing numbers.
Give students with limited attention spans or "attention deficit disorders"
a bright red ink pen or pencil to work with. This helps them stay focused.
Other bright colors work, but I've had the best luck with red.
You know your class better than anyone else. You may decide that you need worksheets at least sometimes.
Here's how to make them:
Select the rows of problems, which you want to use from the following work sheet.
Select one or two rows for Kindergarten, and two or three rows for first and second grade.
Copy and paste the rows you want to use into a worksheet.
Change the orders of the rows and you have a second work sheet.
Do this as many times as you like, using as many rows as you need.
Make as many worksheets as you need from this same set of problems.
Spruce up your work sheets by drawing a picture, or adding a bit of clip copy to them.
Let color the clip copy after they have finished solving the problems.
Print off your worksheets and race your colleagues to the photocopy machine.
Now here's how to type your own worksheets on the computer using your own problems. It is easier than it looks. First, go to the font and size you want to work with. Second, type a line of numbers on your page like this: 123456789. Third, type a line like this underneath that lines like this. +1+2+3+4+4+5+6 etc next, uses you mouse and your space bar and spread them out the way you want them. Finally, use your broken line to put the line under the problem. (The solid underline, is too far down the page.)
Math races are good way to get kids to do worksheets.
Recognize the winner each time with a reward or a cheer.
Here's how to make flash cards.
Get tag board if you have it or old manila folders if you don't.
Cut the Tag board into pieces approximately 2 1/2 by 4 inches.
Write the problem on the front and the answer on the back.
Make a set for each student.
Get an assistant or older students to do this.
Talk one of your fourth or fifth grade teachers into having his or her students
To take on a project of making flash cards for your kindergarten students.
Assessment
¨ This lesson plan can be used for as long as you are teaching one digit addition.
¨ Use it for three months in kindergarten
¨ Use it for four weeks in first grade.
¨ Use it for three weeks in second grade
