Math Math Math What We Did Today

Today in Math class we:

• CORRECTED our get ready sheet I did pretty good 12 out of 13. Remember for 3. B) it says what is the area of the polygon? Then there is a rectangle with 11 m and 3 m. Read the question and don't put 33 cm2 it should be 33 m2 that got a few people ( area is just length x width)
• We also reviewed prime numbers not Optimus Prime from Transformers. Prime numbers are numbers that only have factors of one and itself. For an example I got, well these are just the numbers I can pull out of my head quickly OK here it goes 2, 3, 5, 11, 7 numbers like that there are also bigger ones to like 3571, 1429, 941, 41
• Factor Trees were what I thought were the hardest for some reason even though I got it right. Uummm lets see I cant really write a factor tree on the computer so I'll just add a picture. (waiting waiting waiting) OK its at the top left and for that factor tree if I had 18 but then I put 2 and 9 below it if I do every thing correctly it should end up as 2,3,3 and I think it can go backwards too. I cant remember little help Mr. O?
• Oh ya I got to do something for that Numbers Between number five. Say you have 49 and 87 and you want to find the number exactly in between. OK you take the 87 then minus 49 that equals 38 then you divide the difference by 2 (the difference is 38) then that will equal 19 then you add the 19 to the 49 that equals 68 and now that is the exact number between 87 and 49. Its 68 isn't that easy? If you have a number like 4 and 9 that will come out to be a decimal 6.5 that's the answer.

• Lets see what else do I got to explain? Oh yes equations that contain a variable like 4x + 1 = 13 im gonna tell you how I do questions like this. Here's my secret do the question backwards like so 13 - 1 /4 = x then it would be 12 / 4 = 3 so x=3 you can also break it into parts too but that's just the way I do it.

In an unrelated note give your parents the parent teacher forms. I hope everyone looks good in there pictures because you don't want to look like a potato some farmers think a potato is a beautiful thing but no not now you don't want to look like a potato.
