Module 11: Integers: Intro and Addition Using 2-color counters to solve integer addition Zero pair- when you add negative and positive tiles together it is called a zero pair.Zero bank-when there are many zero pairs next to each other, the whole thing is called a zero bank. (it helps to demonstrate zero for students)We only create two rows if there are both positive and negative tiles. If they are all the same sign they can go in the same row. \https://youtu.be/GG5De8-ETFg?feature=shared

For each problem, it will depend on whether or not you need to build a zero bank. If you can subtract without using a zero bank, you do not need to create one. You are required to create one when you cannot do what the problem asks you to do. https://youtu.be/ZjiL7GfxgiI?feature=shared

Note: Hector's method does not work for subtraction. It only works for addition.

Module 13: Multiplying/Dividing IntegersShowing Integers: Multiplication https://youtu.be/K_tPbVPfHgk?feature=shared

Solving Integers: Multiplication/DivisionWhen multiplying or dividing, if the signs are the same, it's positive. If the signs are different, it's negative.

Building Integers: MultiplicationWe need to build a zero bank whenever we don't have what the problem is telling us to do.

Module 14: Order of Operations/ExponentsThe order of operations is the order in which we are required to do certain operations in order to get the same answer. Groups are identified by addition and subtraction signs, or numerators and denominators. https://youtu.be/dAgfnK528RA?feature=shared
