Keyboard Shortcuts for typing math

Now that we have our homework help site up and running, information on the best way to type in math problems to send as questions would probably be useful to you. For that reason, please find below some keyboard shortcuts for math symbols as well as some links to great equation editors and other cool stuff.

Alt+b = ?
Alt+j = ?
Alt + o = ø
Alt+ p = ?
Alt + v = ?
Alt + w = ?
Alt + x = ?
Alt + z = ?

When to take Geometry.

The typical sequence is Algebra, Geometry, Algebra II with Trigonometry, and Calculus. Where a particular student gets in the sequence depends on when you start, but the further along you get the better. (Think college entrance exams here.) In order to work this sequence out you will need to start in the 9th grade with algebra. However, do not push too hard if they just do not get algebra. The biggest problem we see at the university level in students of calculus is not a weak calculus background, but a poor handle of algebra.

8th – Pre-algebra
9th – Algebra
10th – Geometry
11th – Algebra II with Trigonometry (also called Precalculus)
12th – Calculus

Geometry is best taken after ALgebra 1 as most geometry curriculums (The one at AskDrCallahan included) assume the student has had one year of Algebra, and therefore includes Algebra Reviews for the student. Now, thats not to say a student cant start with Geometry. It would mean that they would have to skip the Algebra Review sections in the book, but that is a parent-choice. Because it is generally easier to manage, most choose to take Algebra 1 then Geometry then Algebra II. (By the way, Algebra II with Trig and PreCalculus ARE the same course, but thats a subject for another post)

The reason a Geometry book has Algebra Reviews is because of the general sequence in which these courses are taken. The writers don’t want you to forget Algebra concepts while you are learning Geometry, so they have Algebra Reviews along the way to keep you “in the game”, as it were. Students should not take ALgebra II with Trig without having taken Geometry, but they can take Geometry before ALgebra 1. So Optional sequences include:

Geometry

Algebra 1

Algebra II with Trig

OR

Algebra I

Geometry

Algebra II with Trig

Just so you know, Geometry is the one course we offer which alot of students report having covered in one semester. Geometry is just set up to lend itself to a rapid pace, often it does not take students an entire year to complete the course. In a private or classical school, even potentially public schools, they give it a whole year because of scheduling reasons, etc, but the work tends to be heavy on the Algebra Reviews to take up time. At least, that has been my experience as a teacher. Often home school students are able to gather the concepts and complete the work rapidly. However, other home school students are quite comfortable taking a whole year and that should be viewed as completely appropriate. Don’t panic if your student needs more than 6 months, but also don’t panic if it only takes them 6 mos. Start the next subject mid-year. This is why we home school.

History of Saint Patrick

On March 17, 461 AD, the world lost a great saint. Saint Patrick, the patron Saint of Ireland.  In America and around the world, Saint Patrick Day is celebrated as a welcome beginning to Spring and a great reason to throw a party . In this issue, we will discuss the history of Saint Patrick and introduce you to some activities you can do at home to celebrate Saint Patrick’s Day.

When he was sixteen, Patrick was captured and taken to Ireland to be a slave. Eventually Patrick escaped and returned home, but as an adult would return to Ireland convinced of their need for Christianity. While he was there, he built schools and monasteries. Some think that he used the shamrock (the regular 3-leaf clover) to preach about the Trinity.

Saint Patrick’s Day occurs during Lent. In Ireland, it functions as a reprieve from Lent and a chance to eat and drink foods that would normally be restricted. The tradition became very popular.

After the potato famine in Ireland, the Irish moved to many different parts of the word, including America. While boiled bacon and potatoes was the traditional meal for Saint Patrick’s Day, in America they could get cheap beef, and started cooking it in cabbage. The dish took over as an Irish tradition and is still eaten today.

Some cool videos about Saint Patrick can be found below:
