Advice please: My district sent out an end-of-year math test we will have to give next month. One of the questions says to write the following as a fraction: .88 I have not taught my students that you can write .88 as 88/100 or .9 as 9/10, etc. In fractions, I taught them that 10¢ is 1/10th of $1, for example (10 dimes equals one dollar), and that a dime is 10% of the dollar. However, I did not introduce the process of writing .10 as 10/100 or as 1/10. I looked in our district and state standards and found that third graders should be able to translate common fractions into decimals, e.g., .75 equals 75% and .25 is 25%. .88 is not common, I don't think? So, my dilemma: do I now stop the current unit long enough to tell them that .88 means 88 out of 100, or 88/100? And that .4 means 4 out of 10, or 4/10? Is there some relevant example I could use to teach them this? Or, do I just remind them before the test that they can skip whatever they don't understand because we may not have covered it? This seems the best idea because 1) my school is alternative and largely believe in developmental education and learning at one's own pace - hence my lessons involving relevant things like money, music, and time; and not practicing writing a number as a fraction, mixed number, decimal, and percent. And 2) everyone in the district uses Everyday Math except my school. The test is written with EDM conventions such as a circle with a Q in it meaning a quarter, or calling equations "names," as in, "Write two names for 7," with possible answers like 2+5 and 63/9. I'd have to translate all these conventions for them to make sense. My school philosophy does not emphasize standardized curriculum or tests, and I will not get in trouble for poor scores in my class. However, the kids stress out when they don't understand things on tests, and it's a waste of time to administer the test as written. Thoughts??
