up for my newsletter OR to Math Mammoth email tour at the address below: Maria's Math News, Vol. 51, March 2011Hello again! Hope everyone is doing fine! This time I have some problem solving examples, and then all kinds of resources and interesting things I found in other people's postings on the Internet. 1. Math Mammoth news 2. Games 3. Seniors & juniors algebra word problem 4. A percentage problem and a video 5. Tidbits 1. Math Mammoth newsSomeone asked me about prealgebra, algebra 1, and Math Mammoth 6th grade."I am confused about what students should study between elementary (K6) math and Algebra 1. Most elementary math programs end after grade 6, then their seems (to me) to be some sort of ambiguity until Algebra 1. Do I understand correctly that if a student masters the K6 math concepts that the next step would be a year of PreAlgebra, then on to Algebra I? So in other curricula what they would call 7th or 8th grade math would be the same material as "prealgebra"? And specifically, when my children master the materials through 6th grade Math Mammoth that a year of PreAlgebra would next, then on to Algebra 1?" She is very correct. A student who has studied through Math Mammoth grade 6 can go on to prealgebra. Prealgebra is sort of an "inbetween" course that covers a lot of review (fractions, decimals, integers, percent), the basics of solving firstdegree (linear) equations, the Pythagorean theorem, and a few other topics. SOME "mathy" students may even be able to go directly to algebra 1 after Math Mammoth 6. In some curricula, this "prealgebra" may be strewn out to two grades (grades 7 and 8). Please see my recommendations for a prealgebra program here. Then, Homeschool Buyers Coop is running a GROUP GUY on Math Mammoth bundle products. Only for homeschoolers. The discount will be 20%, 30%, or 40%, depending on how many people will take part in the sale, but in the past it's always hit the 40%. The group buy ends the last day of March. The payments are collected and products distributed only after it ends (in early April). => Math Mammoth Group Buy at the Coop 2. GamesI just found several different games in the edition #35 of Math Teachers at Play (which has a great collection of mathrelated blogposts in its own merit, so go check it out).
3. Seniors & juniors algebra word problemHere's a word problem that someone sent me recently:The total number of girls in the combined junior and senior classes is equal to the number of boys in those two classes. If the senior class has 400 students and the junior class has 300 students, and if the ratio of boys to girls in the senior class is 5:3, what is the ratio of boys to girls in junior class?This problem gives a lot of information, and it sounds like it can be solved many different ways. But the first task is to notice what we are given and what we are asked.
4. A percentage problem and a videoCan you help me solve this question? No, the asker's method is not correct. In fact, it looks to me like she is randomly doing operations with numbers... To find 30% of something, a MENTAL MATH method I like is to first find 10% of that something. Read more & see the video 5. Tidbits
