We also utilize the iReady lessons as a remediation tool. The diagnostic discovers the gaps a student has in their math/reading learning and then assigns them lessons. It is a great program!

I'm interested in the current ideas on the following questions in Canada.. I'm a former primary school teacher in Australia and would like to understand the different positions in different countries.
What value is placed on Times Tables/Multiplication Tables in Canada? Are they studied in schools? Do you know if parents are doing them at home? For the first equation in the 12's, would you say 1 x 12 = 12 or 12 x 1 =12?
I'm looking at sales over 24 months. For the first 9 months, I sell 10000 units. In the following 7 months, I sold an additional 10000 units. In the final 8 months, I sold 20000 units for a total sales figure of 40000 over 2 years.
I'm trying to create a sales growth curve that's not linear (I'm sure I sold way less in month 1 than in month 8, so dividing 10000 units by 9 months isn't accurate.) Can anyone help with this? I'd GREATKY appreciate it because I'm pulling my hair out.
You start by deciding what kind of curve you want to end up with, and then do a curve-fitting to your data.
For example, suppose you want to end up with a simple exponential growth curve. You have three data points, so you might have to make it a little more complex. So let's assume you want an exponential growth curve PLUS a linear curve.
So your function would be:
f(t) = # units sold by time t months = a*10**(b*t) + c*t
where a, b and c are parameters to be determined.
You then plug in the data:
f(9) = 10000
f(16) = 20000
f(24) = 40000
a*10**9b + 9c = 10000
a*10**16b + 16c = 20000
a*10**24b + 24c = 40000
So now you have three simultaneous equations in three variables. Once you solve for a, b and c, then you'll have your curve.
So, take equation #1 and solve for c in terms of a and b.
Next, plug that value of c into equations #2 and #3.
Then equations #2-3 are simultaneous equations in two variables, a and b. Solve #2 for a in terms of b and substitute that value of a into equation #3. Then you have one equation in one unknown, b. Solve that for b, then substitute back to get the values of a and c, and you have your non-linear function.
This is a very general approach that you can use with any function f(t), provided that it has 3 parameters, since you have 3 data points.
Another approach would be to define a function f(t), and then use a least-square curve fitting algorithm on your data points.

My wife and I liked it so much that we bought our own copies. Later on TPTB finally woke up and got a site license for the school.
I used it to generate homework and major tests. It was not just a good program, it was as well done as I could have imagined with all of the flexibility and control you could want while keeping it pretty simple to use.
I'm not familiar with the other source cited upthread so I cannot comment on that.

Hi Just a bit confused about what the null hypothesis is in the following example: An estate agent claims that rent on housing in the city is not the same as rent in the country. Asked to state the null hypothesis, given that the average rent in the city is €800. What do you think? Maria
The alternative hypothesis is that rents are different in the city and the country.

There are 2 schools of thought whether the Null can have an inequality symbol with the = sign. That is >= or <= One says no, only a pure equal Another says the <= or >= are acceptable Nulls

My middle school has been using BI Advanced 1 and BI Advanced 2 in the 6th and 7th grades for the last two years. I have been very pleased with all the components including the activity lessons. I use only selected activity lessons due to the amount of class time they require. However, they are excellent.

I have some marbles. I give 25&37; to vic, 20&37; to Robbie, 10&37; to jules. I then give 6/20 of that remainder to my brother, and keep the rest for myself. If I end up with 315 marbles, how many did I have to begin with? please give a detailed answer
