Inv 1.4 - The Chip Model

Problem 1.4

Focus Question: How can you use a chip model to represent addition and subtraction?

In this investigation, we will be using chips to represent positive and negative integers. 

You may have heard the terms, "In the red" (meaning you owe or have a negative amount of money) and "In the black"(meaning have a positive amount of money)

In the image above, there are black positive chips and red negative chips on the board. Some red and black chips have already been put together in "zero pairs" that cancel each other out. Is this image "in the black" or "In the red"? How do you know?

Inv 1.3- Number lines

Problem 1.3 -

Focus Question: How can you write a number sentence to represent a change on a number line, and how can you use a number line to represent a number sentence?

Help Link to a site on number sentences and number lines.

In a number sentence, it is very important to have the following

• A starting value
• A change in value
• An ending value.

Example:                      112˚ F + n = 40˚ F

                                                               start            change    ending

Accentuate the Negative -Operations with Integers

Unit Goals:

In this unit, the focus is on understanding and developing systematic ways to add, subtract, multiply, and divide positive and negative numbers. Students will develop algorithms for computations and will use the order of operations, the Commutative Property, and the Distributive Property to solve problems.

Important concepts outlined below.
