Description of Activity

 Students will assemble and answer equations that
produce negative and positive solutions.
 Students will be able to realize that the sum or addition of
two positive integers is positive.
 Students will be able to realize that the sum of two
negative integers is negative.
 Students will be able to find the sum of a positive and a
negative integer by finding the absolute value of each
integer and then subtract these values. The result takes
the sign of the integer with the greatest absolute value.

Extension Ideas

This tri-fold center can be changed around by changing the
numbers that are stationary on the board or even by not having
any numbers to begin with and the student is having to roll for
both numbers to add or subtract.

Supplies Needed
Construction Ideas

Tri-fold, cardboard box, 4 foam dice, border, felt, colored
paper, art paper, die cut letters, glue, staples, markers, plastic
