![]() ![]() Example: my son tells me he is having trouble understanding how to do matrix multiplication. But now we are back to the same problem with Alg2. This was a big boost for his self-esteem and all of his schoolwork has improved substantially this year as a result. He worked hard and got a B+ for the class and he was able to get back on track with Alg 2 as a junior. It was expensive and it was intense, but he wanted to catch up to his classmates. This past summer, he took an entire year of geometry in 6 weeks at Piedmont High School. and he told me in order to get credit for Alg1, there was no other alternative but for my son to sit through the same boring class again, day after day for a second year - a pointless and frustrating waste. He had to retake the entire year of Alg1 as a sophomore. Though he did OK on tests, he stopped doing homework and taking part in class and he got a D the second semester. ![]() He did not like doing math in a group, it was too slow, and he complained that the class was boring. My older son as a freshman didn't pass the second semester of CPM Alg1. I'm not that familiar with the different rankings and terminology, so please excuse my ignorance here! Neither of my kids is on the math "fast track" - i.e., they didn't take Algebra 1 in 8th grade. The approach no doubt works for some kids, but it is failing my kids miserably and there does not seem to be any alternative but to watch them fail and suffer at math throughout their time at BHS. The math my kids are taking is called "CPM Math", which I believe stands for "College Prep Math". They may be graded as a group, and they are encouraged to turn to their group for help, not to the teacher. They work in groups, reading text and then working problems. What is the most effective way for a parent to give the school feedback about math textbooks and teaching? Who actually makes the decision about how math is taught? Do other high schools in the area use the same approach for math that BHS uses? I'm asking because math at BHS isn't working for my kids at all, and I am trying to figure out what to do about it.Īs I understand it, the approach at BHS is for the kids to learn math on their own and from each other, with little or no instruction from the teacher. CPM Math isn't working for my kids at allĬPM Math isn't working for my kids at all.It's risky for the publisher, though, because they have to rely on the advertiser's ability to monetize the traffic. ![]() Then you pay for the actual traffic you're getting and it's up to you how much value you'll extract out of it.Įven less risky is the CPA (cost per action) model, where the advertiser pays every time the user performs an action (registers, makes a purchase, etc.). You get a bit closer if you're basing the remuneration on clicks (the CPC - cost per click model). It's hard to tell how well the traffic will convert and no CPM calculator will tell you that. ![]() It's loosely tied to value, so advertisers can't be sure how much value they're getting. The CPM model has the virtue of being very simple (in all regards – how easy it is to understand, implement, and bill) and clear to all parties. What may interest you more is one of the reversed equations:įor impressions (how many impressions you're going to get, given your budget): So the CPM formula is CPM = 1000 × cost / impressions. Since CPM is the cost per thousand impressions, then you simply divide the cost by the number of impressions divided by a thousand. The formula for CPM is as simple as the concept behind it. ![]()
