40 mins to an hour
Adding and Subtracting
Goals/ Objectives:
-The Student will be able to add and subtract numbers correctly
verbally or on paper 80% of the time.
-The Student will be able to list the turnaround facts 75% of
the time
-The Student will be able to create their own addition and
subtraction equations on paper and solve them 80% of the
time.
-The Student will be able to say aloud the addition and
subtraction facts 100% of the time.
- The student will be able to sketch math addition or
subtraction problems on the board or on paper 95% of the
time.
Rationale :
I feel that addiction and subtraction are the basis of math, if this is
taught correctly, these skills will be used throughout their math career
as a student and will be used in higher-level math.
Medium
I will first start at the board and start by writing the numbers on
the board that I would like to add or subtract. Then I will show the
students how to add not just with numbers but with symbols as well.
For example: I will write the problem on the board 2+3=___ then
above the 2, I will draw two stars, above the 3, I will draw 3 stars. I
will then have the students count with me the number of stars all

2. together and then put above the 5, the five stars added to make that
number.The I will do the same for a subtraction problem.

Teaching Strategies and Methods
Will ask the students questions along with the lesson I will
teach them. I will use the board and the computers.
Evaluation Methods: Assessment strategies:
I will give them a worksheet/homework and see how well they
do.
Resources/ Credits: the print material, electronic resources, and
websites you already found.
Kidspiration, the board with markers, smart board, online
textbooks and Powerpoints.

4.1.2B. Numerical Operations
Numerical Operations.Numerical operations are an essential part
of the mathematics curriculum, especially in the elementary grades. Students must be
able to select and apply various computational methods, including mental math, pencil-
and-paper techniques, and the use of calculators. Students must understand how to add,
subtract, multiply, and divide whole numbers, fractions, decimals, and other kinds of
numbers. With the availability of calculators that perform these operations quickly and
accurately, the instructional emphasis now is on understanding the meanings and uses of
these operations, and on estimation and mental skills, rather than solely on the
development of paper-and-pencil proficiency.
Technology NJCCCS
Standard 8.1 Educational Technology All students will use digital tools to access,
manage, evaluate, and synthesize information in order to solve problems
individually and collaboratively and to create and communicate

Teaching to different subjects:
Language arts: Get a book that has to deal with addition and subtraction (see
power point). Read them the book and then do the math lesson.
