1 Hook/Attention Getter
Pull up Kahoot to introduce integers.
We are going to use Kahoot! to see what we already know about integers.
2 Direct Instruction
Open Kahn Academy to adding/subtracting integers. Watch video with class.
Discuss process and reasoning of signs in front of numbers. Show number line with positive and negative numbers and show how putting positive and negative numbers together change the value of the numbers.
Model adding/subtracting integers on smartboard.
Pass out white boards, have children solve problems while somone else is working on the smartboard.
Now we are going to learn how to add and subtract integers using Smartboard and white boards.
3 Guided Practice
Open FlipQuiz to integer game.
As students answer questions, ask them to tell how they decided on that answer.
Let's play a game and see what we know.
4 Independent Practice
Use Kahoot and use student's score to determine grade
We will use Kahoot! to see what you know
Write two sets of two problems on the board. Have students to break into groups of two. Use white boards and have one student explain to the other how to solve problems.
Have students switch places.
We are going to break into groups of two and show how to solve integer problems.

|HSN.RN: Extend The Properties Of Exponents To Rational Exponents.|
|HSN.RN.1||Explain how the definition of the meaning of rational exponents follows from extending the properties of integer exponents to those values, allowing for a notation for radicals in terms of rational exponents. For example, we define 51/3 to be the cube root of 5 because we want (51/3)3 = 5(1/3)3 to hold, so (51/3)3 must equal 5.|
|HSN.RN.2||Rewrite expressions involving radicals and rational exponents using the properties of exponents.|
|Use Properties Of Rational And Irrational Numbers.|
|HSN.RN.3||Explain why the sum or product of two rational numbers is rational; that the sum of a rational number and an irrational number is irrational; and that the product of a nonzero rational number and an irrational number is irrational.|
