...OF LEARNING!
Today the Pythagorean Theorem was introduced, stating: a^2 + b^2 = c^2.
If you remember this (and remember for what a, b, and c stand ) then you can do great things!
New vocabulary word of the day: HYPOTENUSE. this is the leg of the triangle opposite the right angle. this is the leg we call "c."
Idea we don't ever want to forget: to "undo" a value which has been squared, take the SQUARE ROOT. example: If 16 = c^2, then (the square root of) 16 = c.
This is an idea that we will explore in greater depth in the future, but it is something I want you to have a taste of before the AMC 8 this coming Tuesday.
To ensure that you have at least a little bit of fun this weekend:
-finish LM 1.8B
-practice AMC (10 questions)
-read section 2.7
-record the properties from 2.7 on your properties chart
-complete section 2.7 (covering the ideas and review)
At first glance, this may seem like a lot. SPREAD IT OUT OVER THE COURSE OF THE NEXT FOUR DAYS. I may suggest tackling the LM one night, the AMC questions another night, the reading and notes one night, and the bookwork another night.
If you have questions, talk to each other. I know you all love to chat - don't stop chatting once you leave the classroom :)

ahhh.....miss hogan, i am totally confused about the polythagorm theorem! I am doing the lesson master 1.8 and i dont understand how to fingure out how long C is if we are given the lengths of a and b. Could i possibly come to school early on monday and talk about this theorem?
also.....i kinda forgot my AMC practice packet at school, so if anyone hasnt started theres, could you possibly fax it to me?
alright, here's the brief overview: you've worked with formulas before. the pythagorean theorem is a formula. ask yourself, "what is the first thing I do when given a formula and different values?" answer: substitute those values! then solve for the unknown!
Please do not come into school today to talk about this - but, you are more than welcome to come chat with me at 8 tomorrow morning! enjoy your day off!
rachel-
i was totally confused bu then i read over my notes and called mollie (it really helped !!)i have a question on 4 b and c i know that you have to find the square root of side a and b added together but i how do i know what a block is !! i am so confused i dont even think the question im asking makes ANY sence!!
o and rachel i will fax you it i have stated some of it but it not a bid deal. whats your fax???
sorry miss.hogan, thats what i meant. I wasnt going to come to school on mnday, i maent 8 on tuesday...oops!
hey guys!
i have a question....when we are showing are works and all of the steps, do we have to write out in words what we are doing for example:
do we have to write:
1. formula - a+b=c
or can we just write
1. a+b=c
?????????????????????
hey guys!
i have a question on the bookwork in section 2.8 #14. It says to solve the equation:
0y= 1/2,
but nothing times 0 will equal 1/2?
so we can not solve the equation!?!
