(ex. milligram) if there is no prefix, then you are starting with a base unit. find the step which you wish to make the conversion to. (ex. decigram) count the number of steps you moved, and determine in which direction you moved (left or right). the decimal in your original measurement moves the same number of places as steps you moved and in the same direction. (ex. milligram to decigram is 2 steps to the left, so 40 milligrams = .40 decigrams) if the number of steps you move is larger than the number you have, you will have to add zeros to hold the places. (ex. kilometers to meters is three steps to the right, so 10 kilometers would be equal to 10,000 meters) that’s all there is to it! you need to be able to count to 6, and know your left from your right! 1) write the equivalent measurement: (.5 pt each) ￼￼￼￼￼a) 5 dm = _______m b) d) 9 mg = _______g e) g) 4 cm = _______m h) j) 7.02 ml = _______cm3 k) m) .32 m = _______cm n) 4 ml = ______l 2 ml = ______l 12 mg = ______ g .03 hg = _______ dg 38.2 g = _______kg c) 8 g = _______mg f) 6 kg = _____g i) 6.5 cm3 = _______l l) 6035 mm = _____cm the metric system of measurement is based on multiples of 10. prefixes are used to indicate what multiple of 10 the base unit is being multiplied by. centi- 0.01 milli- 0.001 base units will include the gram (g), liter (l) , and meter (m) and will have no prefix. unit i – chemistry for life – metric conversion worksheet page 2 of 5 2. one cereal bar has a mass of 37 g. what is the mass of 6 cereal bars? is that more than or less than 1 kg? explain your answer.

♥ at my school we teach an "activity class" or english corner where we have to play games or do activities with adult learners of all levels, mostly beginners (which makes it more difficult). i've been to all the esl websites and used those ideas, but we do this twice a day and we're running a bit thin. any suggestions?classification key to certain fish please help thank you?

♥ i'm 12 and in 7th grade i'm a girlwife wants to homeschool our preschooler?
♥ note: i do not have a problem with homeschooling, or the fact that she wants to homeschool our son. at this point, he's not even old enough for formal schooling. my son joseph is 3. my wife is a stay at home mom and she has decided that she wants to teach him herself for preschool. i have to work, so it would just be my wife and joseph. she's getting really into it, drawing up lesson plans and stuff. there is an example of one at the bottom of the question. she will be assigning him "homework" as well - which he would complete outside the lesson times with her help. honestly, it seems really intense for preschool for me. it's a full day of classes, which would mostly entail him sitting at the table and listening to my wife/doing worksheets. there's no space or time for him to play or take a nap. it's all very rigid. i want my son to get a good education, which is why i want him to learn to enjoy learning - i went to an ivy league and i noticed a big difference performance-wise between the kids who were honestly curious and loved to learn and the kids who just wanted a fancy degree and didn't give a rat's *** about what they were studying - not to mention that i want him to be happy. in short, it would be a damn shame if he's burned out by the time he starts kindergarten. what do you think we should do? personally, i would feel a lot better if it were more along the lines of "reading time, free play time, art time, play games outside, lunch time, nap time, go to the library/zoo/farm, etc." here's the sample lesson plan: 8:00 - reading (the giving tree). read once to him, once together, once by himself. 8:30 - math - practice writing numbers 0-9 9:00 - social studies - learn the following words: continent, country, ocean, north, south, east, west 9:30 - physical education - have him practice catching and throwing ball 10:00 - writing: practice writing the following words 10 times each: boy, cat, man, dog, toy, bed 10:30 - computer time - 30 minutes of jumpstart preschool 11 - art - practice cutting out shapes along dotted lines (circle, square, triangle, heart, star) 11:30 - science - learn the names of the planets 12 - music - learn "twinkle, twinkle, little star" on piano (right hand only) 12:30 - lunch time 1 - french - use tapes 1:30 - language arts - using pronouns (e.g. "i am happy" not "me happy") it's not that i don't think he should learn how to read - in fact, we have already started working on it. i just don't think 3 year olds are develomentally at the point where a schedule like that is needed - i mean, for christ's sake, language arts is on there.
