Mathematics Extra lessons Grade 8 to 12

😅😅😅😅😅
That's Maths for you.

😂😂😂

Great summary

Formulas in Solid Figures

You need to know when to use each of these laws.

And knowing that comes with continous practice.

Laws of exponents

Huuh. I see my self mad, when children forget the mathematics records book at home. I don't know why we teachers feel like this 🤔🤔. I think we Put too much passion into the teaching 🤔🤔. Personally I desire all my records with the leaners to be in one book, so that when children forget what I discussed before, there's apoint of reference.

The learners I teach know. I complain alot when they write my work in rough books. Actually I tell them to cut and paste the page they wrote on into the main book of records that they say they forgot home.

I’m cooked

Sharing is aimed at encouraging someone out there.

Do not let people project their fears on you . Go back to school if you want.

Word 🤔🤔🤔

The truth is, you don’t really know what your limits are. Keep going.

Nice examples

I loved this Qn: Required to Find standard deviation.
It was revision with some of the Gr 12's who showed up in the holidays . This is when the children who do not master formula and their usage are caught.

Qn: How do you tell if a number pattern/sequence is Quadratic?
Answer: It has the 2nd difference common(the same).
Meaning the general term/rule /nth term/formular of getting numbers of sequence takes on the form:
Tn =an² +bn +c
To find a , b and c.
We use the summary

●2a=2nd differences
(This helps you get a)

●3a+b= 1st number, in the set of 1st differences .(This helps you get b since you a earlier).

●a+b+c=T1
This helps you get c since you a and b earlier).
Note:
To find c you can also use any number of the sequence if you know its position by substituting in Tn =an² +bn +c .
Though the most convenient way to find c is to use a number in position one. I.e T1.
