Honors Math- Be prepared for your math exam this Monday(1/26/15) Go over your review that will be given to you on Friday (1/23/15). Make sure you go over all your notes and know how to find the whole/total, part, and percent in word problems. Go to my last blog for more examples.
We will begin to work with exponents, prime factorization, and Order of Operations (PEMDAS) this week. I know we have reviewed these 3 content areas but we will go more in depth for each category.
BELOW ARE EXAMPLES FOR EACH AREA AND A LINK FOR (PEMDAS)
Exponents are shorthand for repeated multiplication of the same thing by itself. For instance, the shorthand for multiplying three copies of the number 5 is shown on the right-hand side of the "equals" sign in (5)(5)(5) = 53 (so 5 to the 3rd power equals 125).
PRIME FACTORIZATION:
Example: 48
48 = 8 × 6, so we write down "8" and "6" below 48
Now we continue and factor 8 into 4 × 2
Then 4 into 2 × 2
And lastly 6 into 3 × 2
We can't factor any more, so we have found the prime factors.
Which reveals that 48 = 2 × 2 × 2 × 2 × 3
(or 48 = 24 × 3 using exponents)
ORDER OF OPERATIONS
GEOMETRIC CONSTRUCTION:We will finish working on our cubes created by straws. We will also test the bubble theorem with our cubes.
CLASS DISCUSSION: Why we learn about constructions.
REMINDERS:
PROGRESS REPORTS ARE AROUND THE CORNER SO STAY ALERT IN CLASS!
TRY YOUR BEST NOT TO BE ABSENT.
ALWAYS TRY YOUR BEST NO MATTER WHAT!
Below are some pictures of students working on their cube project made out of straws and fishing line.
