TITLE:  ADDITION AND SUBTRACTION GAME

AUTHOR:  Kaye Miller; Lincoln City Jr. Academy,

GRADE LEVEL/SUBJECT:  Appropriate for grades 2-8

OVERVIEW:  A group activity that provides review and drill
in the format of a game for learning facts in subtraction
and addition. Appeals to multilevel and multigrade
situations. The Students get so caught up in the game they
consider it an exciting challenge rather than a drill or
review.

OBJECTIVE(s):
1. Practice addition and subtraction facts and processes.
2. Use accuracy in adding and subtracting.
3. Develop speed when adding and subtracting.
4. Understand the concepts of adding and subtracting.

RESOURCES/MATERIALS:
  1. A die
  2. Lined paper
  3. Pencil

ACTIVITIES AND PROCEDURES:
1.  Draw on the board three parallel lines then two
intersecting lines.  Place a "+" or "-" sign next to the
second parallel line.  What you have made is a grid of empty
boxes, with three boxes in each of the three rows.
2.  Have the students copy this onto their papers.
3.  Explain to the students that you are going to roll a die
and the number that is rolled is to be placed into one of
the squares in the top two rows. The bottom row is for the
answer.  The die will be rolled until the empty boxes in all
the rows, except the bottom row, are filled.
4.  They are then to work the problem.
5.  The object of the game is to get the highest number if
adding or the lowest number if subtracting.
6.  While the students are putting their numbers onto their
paper you are also playing by putting your numbers into the
squares on the board.
(I found this to help the slower students, and the quick
students try to beat you.)
7.  Then ask if anyone beat your answer.  The best answer is
written on the board and anyone with that answer receives a
point.
8.  Create smaller or larger grids to adapt to your students
level.

TYING IT ALL TOGETHER: This should be a group "fun"
activity.  Not only does it give them a relaxed environment
to practice the skills they've learned but it gives you a
chance to evaluate their progress.
