Last call for HOTM conference


You still have time to sign up for Heart of The Matter virtual homeschool conference. It starts next week.

The price for this is $29.95.

I will be speaking on Sunday the 3rd, on the topic of "Teaching Math in Homeschool". That is a really general title, and so I will be looking at some broad ideals and goals of teaching math in a homeschool setting, such as:

What goals should you have when teaching mathematics in a homeschool setting? What about choosing the right homeschool math curriculum? What is important, what is not?

After each talk, there's t! ime for questions and answers session. It all happens online using a online conference software.

Go here to register for the conference, see the list of speakers, etc.
Please mention that I referred you.

Lviv .NET User Group: My presentation on NHibernate

Hello, as many of you know yesterday I spoke to NHibernate at local .NET User Group.

I won 20 beers, because we've got > 30 attendees

It was group's 4-th meeting and it went extremely well. Above 40 people participated and for me it was biggest audience I ever had to talk to during one hour or so. For another speaker - Derik Whittaker - I'm sure that this is not biggest audience he had, but maybe the biggest foreign language speaking audience. If I'm wrong please correct me.

Audience asked questions

People were asking me lot of questions and I tried to answer quickly and easily, but keeping in mind that I should continue and be in time, since it is bad practice to overtime speech.

I asked questions

To my own surprise flow of delivering this presentation was so smooth and harmonic with audience. Asking people simple questions, making them shaking their hands and keeping attention, because maybe another time I'll ask exactly someone from them.

I'm proud for my presentation skills

From day to day I become better in my ability to talk easily to technical audience. This time I've got the most sophisticated audience I ever had. They all had good experience working on different projects. So it was not like talking to university guys, who are very "green" in their understanding of technology and how things should look like.

Presentation itself

You could take a look at my presentation below.

Not enough time to finish my second demo

For my second demo I allocated about 20 minutes, but it turned out, that I got about 10 and also talking to it and coding takes longer than sitting with my own keyboard and typing it at light speed. So sorry guys for not showing what I planned there.
What was planned and I did not show is: demoing lazy loading, chasing, complex Criteria API, and maybe the interesting - implementing own UnitOfWork and NHibernate repositories, approaches to build domain model with NHibernate.
BTW: I'm also going to have another blog post on NHibernate itself.


Really looking forward to get your feedback! Please leave your comments!

  • Graphing Calculator Resources
Dh ! and I ne ver used a Graphing Calculator in India even though we had to learn much more advanced Calculus than the AP Calculus courses here. There were memorization and manipulations involved in solving advanced Calculus problems without having to resort to a calculator of any sorts. I am not sure if Graphing Calculators are used these days in India by all high school kids. We very much doubt that it would be practiced considering the prohibitive cost of these calculators to be able to afford by all Indian high school kids. We have exposed dd to both the version of learning with and without a graphing calculator, although the latter learning is not necessary to do so here in the US. She loves her Graphing Calculator although she enjoys working without them too.

Dd uses the above pictured Graphing Calculator for advance mathematics, mathematical programming, 3D graphing, along with numerous other tasks. There are numerous resources on the web regarding Graphing Calculators. I have listed a few below.

Interactive Numberline

Ambleside Primary has done it again! In addition to their hundreds chart and their multiplication chart, they also have an interactive number line. The number line comes with 7 colored squares that you can use to cover the numbers so that students have to calculate what number is missing. This would be great on a Promethean board, too! Notice at the bottom of the s! ite, there are blue buttons with options for different types of number lines: 1's, 10's, 100's, 0.1's, 0.5's, -5 through 5, or create your own under the section entitled "Make a line". Just specify the number you want the line to begin at and the increments to count up by and click "Go". You end up with your own personalized line! If it the site allowed you to display more than 11 numbers at a time, it would be even better.

The Math Worksheet Site has a number line generator, but instead! of it being a digital, interactive image, it creates a worksh! eet that you can print out. The site does not limit the values you can put into the number line, so some number lines may print out very small. This is a nice option for teachers to know about who use number lines to teach basic math. If you have a Promethean board, you can generate the number line, and then use "Annotate Desktop" to write over the number line at the board.

Intercept calculator

x intercept calculator

Find x & y intercept for the line equation 4x + 5y = 9
Solution:

Step 1: Given equation

4x + 5y = 9

Step 2: Find x intercept

To find x intercept, plug y = 0 in the given equation 4x + 5y = 9 & solve for x

4x + 5y = 9

Plug y = 0,

4x + 5(0) = 9

4x = 9

Divide both side of the equation by 4, they get

x = 2.25

Therefore, the x intercept of the equation 4x + 5y = 9 is (2.25, 0)

Step 3: Find y intercept

To

4x + 5y = 9

Plug x = 0,

4(0) + 5y = 9

5y = 9
Divide both side of the equation by 5, they get

y = 1.8

Therefore, the y intercept of the equation 4x + 5y = 9 is (0, 1.8)

Step 4: Solution

X intercept = (2.25, 0)

Y intercept = (0, 1.8)

Graphing Linear Functions

Just recently I was working with a student on graphing linear functions during a tutoring session. She asked if there was anything she could work on to continue with her practice. This prompted me to get on the computer and do a search for some lessons and interactives that might help her.

I started my search with Hippocampus.org. The full Algebra 1 class has an entire chapter devoted to graphing linear functions. This is a wonderful place for students to start if they are having trouble with the concept or need a refresher.

I also came across some great interactives that can really help students. The first is an online graphing utility that I have used in the past called GCalc. This will allow students the ability to graph any function, including linear functions.

The second is a Shodor Interactive that will also allow students to graph linear functions. You may ask why give students an opportunity to graph functions with technology instead of with paper and pencil methods. I am a huge proponent of doing both. Students need to know the mechanics of graphing functions on their own, but we should also expose students to the technology that is available to them.

I also found two sliding interactives. Students are able to move a slide that changes the slope and y-intercept of an equation and they can see how these changes affect the graph of a linear function. One of these interactives can be found at mathsnet and the other at id.mind.

Finally, I found a site that offers free graph paper. I think that is also important when students are practicing these skills.
