Ok, we ran out of time today because of the Curriculum Fair. Below, you will find the example problems I would have given you in class today along with my own made up practice problems.

Aim 1: to find the sum of the first "n" odd integers

Make your own term and value chart. Label the top row "# of odd integers". Label the bottom row "Sum". Then, calculate the sum by completing the following:
1
1+3=?
1+3+5=?
1+3+5+7=?
1+3+5=7+9=?

# of odd integers 1 2 3 4 5 n
Sum 1 4 9 ? ?

Complete the conjecture:
The sum of the first n odd integers is __?__

Practice Problems:

1. Find the sum of the first 80 odd integers.
2. Find the sum of the first 90 odd integers.
3. Find the sum of the first 100 odd integers.
4. 1+3+5+...+253=?
5. 1+3+5+...+987=?
6. 1+3+5+...+1269=?
7. 255+257+259+...+757=?
8. 339+341+343+...887=?
9. 551+553+555+...+1111=?

Aim 2: to find the sum of the first "n" even integers

Make your own term and value chart. Label the top row "# of even integers". Label the bottom row "Sum". Then, calculate the sum by completing the following:
2
2+4=?
2+4+6=?
2+4+6+8=?
2+4+6+8+10=?

# of even integers 1 2 3 4 5 n
Sum 2 6 ? ? ?

Complete the conjecture:
The sum of the first n even integers is ____?____

Practice Problems:

10. Find the sum of the first 250 even integers.
11. Find the sum of the first 700 even integers.
12. Find the sum of the first 1000 even integers.
13. 2+4+6+...+500=?
14. 2+4+6+...+1000=?
15. 2+4+6+...+1600=?
16. 450+452+454+...+988=?
17. 234+236+238+...+1290=?
18. 886+888+890+...+2000=?

Aim 3: to find the sum of the first "n" consecutive integers

Complete your own term and value chart. Label the top row "# of consecutive integers". Label the bottom row "Sum". Then, calculate the sum by completing the following:
1
1+2=?
1+2+3=?
1+2+3+4=?
1+2+3+4+5=?
1+2+3+4+5+6=?

# of conescutive intergers 1 2 3 4 5 n
Sum 1 3 ? ? ?

Complete the conjecture:
The sum of the first n consecutive integers is ___?___

Practice Problems:

19. Find the sum of the first 20 consecutive integers.
20. Find the sum of the first 100 consecutive integers.
21. Find the sum of the first 1600 consecutive integers.
22. 1+2+3+...+500=?
23. 1+2+3+...+950=?
24. 1+2+3+...+4280=?
25. 450+451+452+...+921=?
26. 263+264+265+...+900=?
27. 567+568+569+...+789=?
28. 678+679+680+...+1616=?

Please post your completed conjectures first. It takes 3 out of 4 people in your group to establish a rule. Since we're not in our groups, we'll have to do something else to establish our conjectures as rules. Let's say that your conjecture isn't a rule until 6 other people have agreed with you. Once 6 people have agreed on the conjecture for Aim 1, then that's the rule we will use to solve the practice problems for Aim 1. We will use the same process for Aims 2 and 3.
Good Luck! I know they're hard. Struggling isn't a bad thing. It builds character. Who knows? You might even surprise yourselves tonight. If not, you know I will help you out of the hole tomorrow. I promise.

Please post any comments, questions, or concerns here. PG-13 only! I will check the blog periodically to help. Have fun!!!!!!!!!!!!!!

Welcome!

WELCOME!!!

You have entered the danger zone. Warning! Warning! Warning! (sirens blaring in the background....woop! woop! woop!) You have just arrived at your new blog site. This is the place where I will post your homework assignments, news events, and notices of upcoming tests. It is also a place where you can communicate with your fellow geometricians as you make that slow, treacherous journey through my Geometry Honors class. I LOVE this course and take great pride in teaching it. It is my hope that you will eventually develop the same passion for it that I have. If not, at least gain enough knowledge to perform at a very high standard on the SAT or ACT.

Anyhoo, use this blog as a means of communicating with your fellow classmates. For instance, if you don't know how to do problem number 11 tonight, then you can post it. Hopefully, someone will read your posting and respond with a hint or an explanation of how to arrive at the answer. Use this blog to your benefit.
Also, there are helpful mathematical links on the left hand side. Click on each of them to see what they look like. Every now and then, I will offer extra credit for logging in to some of these sites.

Until then, happy blogging!!!!
Ms. Chan
