This video shows the most spoken languages in the world, between the years 1900 and 2023.

It is difficult to define what constitutes a language as opposed to a dialect. For example, Chinese and Arabic are sometimes considered to be single languages, but each includes several mutually unintelligible varieties and so they are sometimes considered language families instead. Conversely, colloquial registers of Hindi and Urdu are almost completely mutually intelligible, and are sometimes classified as one language, Hindustani, instead of two separate languages. Such rankings should be used with caution, because it is not possible to devise a coherent set of linguistic criteria for distinguishing languages in a dialect continuum.

There is no single criterion for how much knowledge is sufficient to be counted as a second-language speaker. For example, English has about 450 million native speakers but, depending on the criterion chosen, can be said to have as many as 2 billion speakers.

There are also difficulties in obtaining reliable counts of speakers, which vary over time because of population change and language shift. In some areas, there is no reliable census data, the data is not current, or the census may not record languages spoken, or record them ambiguously. Sometimes speaker populations are exaggerated for political reasons, or speakers of minority languages may be under-reported in favor of a national language.

Du kan lære at dele tal sammensat af forskellige cifre ved hjælp af standard algoritme.

Du kan ændre antallet af cifre i tæller og nævner.

Du kan vælge mellem mulighederne, fortsætte eller genstarte, hvis du begår fejl.

Fortæller kort om hvor vigtigt det er at have styr på sine 1 til 9 tabeller og at videreføre 'rester' i udregningen.
Filmen siger også, at selv om der er 4 metoder at dividere på, og sikkert flere end det, er det vigtigt at man finder den metode som man selv bedst kan finde ud af at bruge, og så holder fast i den ene metode fremover.

Multiply by 4 and learn the 4 times table with a tropical beat. Sing along to the 4's times tables by singing along with the multiplication fact the first time through. The second time through we delay the answer so students can give the answer and then the answer is reinforced. The third time we supply the 4's times table and leave the answer blank for higher order learning.
Multiply by 4's with this catchy tropical tune to help student's learn their 4 multiplication table in order.
This song goes through each table 1 through 12 three times to give your children a chance for lots of practice.
This song also has a gradual learning structure.

First time: I sing the multiplication table I give the answer.

Second time: I say the table I delay the answer, so children have a chance to answer before me.

Third time: I completely omit the answer so children can answer on their own.

This song on learning how to Multiply by 4 is a wonderful way for your children to learn and practice the multiplication tables.

Multiply by 4's

Four quarters in a football game
Four sides to a square are the same
Four wheels to a race car turn

4 x 6 is 24
4 x 7 is 28
4 x 8 is 32
4 x 9 is 36
4 x 10 is 40
4 x 11 is 44
4 x 12 is 48

Four quarters in a football game
Four sides to a square are the same
Four wheels to a race car turn
And the 4 times table I can learn

Now say the answer before me

4 x 1 is 4
4 x 2 is 8

0:00 Memorize Multiplication
1:03 The 1's
1:22 The 2's
2:38 The 3's
3:53 The 4's
4:49 The 5's
6:07 The 9's

When teaching a student to memorize the multiplication tables it is not as big of a challenge as it seems on the surface. The first reason is that the 1's and 10's are super easy. Any number multiplied by 1 is the number and any number multiplied by 10 you just add a zero to the number.

That is 20% of the table!

The 2's, 3's and 5's can be solved by teaching the student to learn to count by 2's, 3's and 5's. Also using the PLUS 4 and PLUS 4 strategy for learning the multiplication of 3's and 4's is helpful.

When memorizing the multiplication table you will also find some tricks like understanding that when a number is multiplied by 9 the answer adds up to 9. So 4 X 9 = 36 and 3+6 = 9.

The main thing when memorizing the multiplication tables really isn't to memorize them it is to learn the multiplication tables or to understanding the multiplication tables.

Watch this short animation to discover how castles developed during the middle ages. We trace their evolution from early motte and bailey castles in Norman times to the sophisticated structures of the late medieval period, and explain why castles were as much about status as defence.
