Total Duration: 
31 to 60 Minutes 
Materials and Resources: 
Pencils Notebook Paper Rubik's Cube and website to help https://www.rubiks.com/ Small cube blocks  enough to have 100 blocks for each group of 4 students Handheld calculator if 1to1 technology is not available Videos from the website “Khan Academy” Worksheet for Acceleration Activity Worksheet for accelerated students to be copied  http://www.commoncoresheets.com/SortedByGrade.php?Sorted=8ee2 Worksheet to be copied for all the students  Rational and Irrational (see attached document) Worksheet to be displayed on the interactive whiteboard  Bell Ringer Squares and Cubes (see attached document) Worksheet to be copied for all students  Equations with Roots (see attached document) Worksheet to be displayed on the interactive whiteboard  Exit Slip Radicals (see attached document) 
Technology Resources Needed: 
Desktop computer with interactive whiteboard and wireless internet iPad, Chromebook or MacBook for each student Khan Academy video for introduction to rational and irrational numbers: https://www.khanacademy.org/math/algebra/rationalandirrationalnumbers/alg1irrationalnumbers/v/introductiontorationalandirrationalnumbers Khan Academy video for introduction to squares and cubes: Calculator 
Background/Preparation: 
Teacher: The teacher will need to preview the video and other materials that are listed in the resource section. The teacher will need to make sure that he/she has enough blocks for the entire class. The blocks do not have to be the same color, but they do need to be the same size. Having blocks of identical sizes will prevent students from becoming confused.
Student: The student will need prior knowledge of changing decimals to fractions. The student will need to know that a repeating decimal is a rational number. Rational numbers are those numbers that can be written in the form of a fraction. The video will explain the concept briefly. The student will need experience in solving equations using inverse operations. 
Before: Bell Ringer:
During:
After: The teacher will display the document, “Exit Slip Radicals” on the interactive whiteboard. The students will complete the exit slip on their own paper. The students will turn in the exit slip as they leave the classroom. If the accelerated students finish early, then the teacher will assign work from the website "Common Core Sheets”. The website is http://www.commoncoresheets.com/SortedByGrade.php?Sorted=8ee2. The teacher should have created the assignment in advance. 
Attachments: **Some files will display in a new window. Others will prompt you to download. 
Assessment Strategies 
Informal: The teacher can ask questions while reviewing the classwork worksheet "Rational and Irrational". The teacher will check for student understanding with the worksheet "Equations with Roots". Formal: The teacher will check for mastery using the Exit Slip while taking into consideration the student's comprehension of the mathematical concepts observed during the lesson. 
Acceleration: 
If accelerated students finish early, then they can work on a more challenging equation worksheet with radicals "Challenging Radicals". ( http://www.commoncoresheets.com/SortedByGrade.php?Sorted=8ee2) 
Intervention: 
The intervention students can be placed in groups with a manipulative and peertutor. The students can be given more time to complete the assignments and oneonone help.
