Please submit an electronic copy of your work!
The library has pdf scanners and can assist you with this should you have any questions. Or use your phone or tablet to take a photo and submit that as evidence of your work.
Peer Review!
We will be reviewing each others work for clarity and accuracy in class on the 2nd. Please note that we will be in the computer lab for this exercise.
You do need to be sure that your paper is submitted on time. Following submission, your assignment submission page will read: "Turned In!". On the 1st, Canvas will automatically assign a paper to you for review. You will need to return to the assignment submission page on the 2nd in class to complete this exercise. From there:
- Look for the words Assigned Peer Reviews and a link with the name of your peer-review partner below the "Turned In!" message on the assignment submission page.
- Click the link to your peer-review partner to access the peer-review page.
- Click the preview (magnifying glass) icon to view your review partner's assignment onscreen.
- Using the rubric below evaluate follow along in class as we evaluate 12 problems together. During this time it is your job to add comments to your partner's paper using the commenting tools and assess points.
- Ask questions as needed!
We will review this process in more detail in class so please do not worry if this seems complicated; I promise there will be a demonstration and this will be fun and easy!

8.EE.1: Work with radicals and integer exponents.
Know and apply the properties of integer exponents to generate equivalent numerical expressions. For example, 32 × 3–5 = 3–3 = 1/33 = 1/27.

8.EE.2: Work with radicals and integer exponents.
2. Use square root and cube root symbols to represent solutions to equations of the form x2 = p and x3 = p, where p is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that √2 is irrational.

8.NS.1: Know that there are numbers that are not rational, and approximate them by rational numbers.
Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number.

8.NS.2:Know that there are numbers that are not rational, and approximate them by rational numbers.
2. Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., π2). For example, by truncating the decimal expansion of √2, show that √2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations.
