If you did not finish the test today, you may have more time after lunch on Monday. I will come to your classroom. Do not go to the library.

Well done 8th grade! You are rocking the Pythagorean Theorem. Tonight and tomorrow work on a study guide for the Pythagorean Theorem section. We will have the exam on Friday.

On HW #4 complete up through #4. Ideally, try #5-7 also.

Reminder: we will have an exam on Pythagorean Theorem before break. Perhaps F 12/12 or T or W of the following week.

Finish HW #3 for Friday. You may begin HW #4 if you would like.

Finish Group Worksheet #3 if you haven't already, including the challenge.

Homework #3 - Questions #1-2

If you weren't in class today, work on Pythagorean Theorem Group Worksheet #3.

Finish Pythagorean Theorem Homework #2. I expect everyone to complete the challenge question - #7. You may work with your classmates to complete it. This problem will be collected as a separate homework.

Homework #2 - #1-4

On Group Worksheet #2 - complete #1, 2, 4, & 5. Save further work on #3 for class on Thursday.

Alternate assignment (Only do this if I assigned this to you specifically in class.)

Finish #4 on HW #1, complete #1 & 2 on Group Sheet #2.

Complete the homework we started in class today.

Complete Pythagorean Theorem Group Worksheet #1.

Part 1

Using the algorithm (method) we learned and practiced in class, find the square root of the following numbers:

0 a) 892.156

0 b) 643.1296

1 a) 613089

1 b) 1004.89

1 c) 71

If you do not find an exact answer round to three decimal places (this means, use the algorithm to determine 4 decimal places then round to three decimal places)....[read more]

Following the process we started in class, try to find the square root of 780.0849

Finish finding the square root of 7203856. In class we decide it had 4 digits, ends in a 4 or 6, and begins with 26. Using the method we did in class, find the final two digits and therefore the square root of 7203856.

Draw, label and cut two more 8 x 8 squares as we had done in class today. Use only whole number divisions.

From the work we did in class:

- Complete the table of X and X^2. Do this by hand - show your work - do not use a calculator.
- Then complete the 'n' and its square root digits table that we began in class.
- Then using the method we discussed and practiced in class, find the first digit of the square root of the following numbers. Show your...

Ponder the question below and try to come up with three ideas that could work for this. You must write it out, having it prepared to hand in, and you should be prepared to discuss in class.

- Given a certain number, how can we know exactly what the first digit of its square root is?

You did a great job on today's exam. Relax a bit tonight or catch up on other homework or class work.

You should be spending 15-30 min per day studying for the Number Bases test on Tuesday, November 4. Studying entails working through a variety of problems. The class created a list of areas and types of problems in class on Friday and Tuesday. Use that to guide your studying. You also created 4-6 example problems in class today and shared...

[read more]Bring in questions on areas or specific example problems for us to go over in class. You should be spending 20-30 minutes studying tonight.

Use the study guide we worked on in class today to start studying for our exam on number bases.

I will be in your classroom at 12:40 on Monday for anyone who needs extra time for Thursdays quiz and to answer questions.

What would you include in a study sheet?

Finish HW #7, if you have not already. If you have, start preparing for the Number Bases exam.

Finish Group Worksheet #7, if you didn't in class.

Finish #1-3 on HW #7. You may do more if you wish.
