Assignment 5: The Black and Red Chips Model
In class, the black and red chips model was used to illustrate positive and negative
numbers. Each black chip represents +1, each red chip represents -1, and a black and red
chip together equals 0. With this model, we saw that there are infinitely many possible
ways of illustrating each number.
1) For the following numbers, sketch four different types of sets of black and red
chips to represent each number:
a. 0
b. 8
c. -4
In class, we also used the black and red chips model to represent operations of signed
numbers.
2) Illustrate the following computations and answer using the black and red chips
model. Remember that there is more than one way of representing each number.
Do NOT alter any of the operations (making subtraction into addition or reversing
the order of multiplication).
For each illustration, include the numerical answer using typical methods of
computing signed numbers:
a. 11+ି7
b. ି 9 + 6
c. 13 − 5
d. ି8 − 4
e. 5− ି3
f. 7 ∙ ି2
g. ି3 ∙ 6
h. ି4 ∙ ି 3
i. 12 ÷ 4
j. ି12 ÷ ି4
k. ି12 ÷ 4
***BONUS***
Create your own method to show 12 ÷ି 4
