Ch8-math A Refresh     Ch10-math B Refresh

From now on,

you are going to work specifically 

on Chapters of your choice of Maths!

Math A pupils...

Start doing Ch 8 STATISTICS now.

Later there will be a LessonUp part for you.

First the Math B pupils get a short Introduction to 

Ch 10 Refresh, p.90/91.

Introduction for Ch 10 REFRESH, p.90/91

-math B:

QUESTION:

What MATERIALS do you need to do the

REFRESH?

Watch the next slide and give your answer on the slide thereafter!

These MATERIALS:

Quite a lot! (If you forgot anything, make sure the coming lessons you bring everything!)

Among others:

+ pair of compasses                + Casio

+ pencil                                          + geo triangle

+ geo triangle                              + Workbook 3B, etcetera...

Question about R4.

Watch the next slide and fill in your answer in the slide after that one.

'identical' triangles means that they ....
Choose the best answer!

1. have the same angles.
2. have the same sides.
3. have the same angles and sides.
4. are almost the same.

Answer the question, that follows the next slide!

The question is about the meaning of the words:

proposition, properties, proof and theorem.

The words: proposition, property, proof, theorem
mean in this text: .........

1. bewering, bezit, bewijs, stelling
2. bewering, eigenschap, bewijs, stelling
3. voorstel, bezit, bewijs, theorie
4. voorstel, eigenschap, proef, theorie

So....

The short paragraph Refresh, p.90/91 may seem pretty simple, but in fact it has a rich content!

Do your best, working out R1  up to and including R5.

Math A pupils, pay attention now!

A little information about:

percentages!

See next slide. 

This is question R1d:

Answer (with explanation):

The way to solve this is:

+ express the New amount in the Old amount, or:

+ do: Old/New x 100 % 

+ see next slide!

Mistake in R2e:

'mean' should be : 'median'!

You may correct this in your paperbook, but ...

only with a pencil!! (avoid financial problems when turning in your books, at the end of the year).

In R2d you are asked to make a 'frequency table', but...

what is that?! Also see next slide!

In 2 colums there is some information:

+ on the left you see the marks that were scored

+ on the right you see how often (frequent!) they were scored.

Homework time.
