Diagrammatic Approach to Teaching English

     I've recently watched a number of videos in which Rupert Lezemore, an independent language consultunt to the EFL industry, talks about a so called 'diagrammatic approach' to the teaching of grammar. Here is a link to the original videos.
       Inspite of the seemingly complicated terminology, the idea is rather simple: using chart, tables and flowcharts makes teaching English grammar and vocabulary more effective, especially for visual learners. It is also important to use variuos colours for presenting language items.
        Personally I love using colours in teaching English. Here is the way I colour the numbers' table to help my students remember the numbers' spelling.

0	zero (nought)	10	ten
1	one	11	eleven
2	two	12	twelve	20	twenty
3	three	13	thirteen	30	thirty
4	four	14	fourteen	40	forty (no "u")
5	five	15	fifteen (note "f", not "v")	50	fifty (note "f", not "v")
6	six	16	sixteen	60	sixty
7	seven	17	seventeen	70	seventy
8	eight	18	eighteen (only one "t")	80	eighty (only one "t")
9	nine	19	nineteen	90	ninety

Another example is introduction of a sentence stucture. Whenever we learn a new type of sentence we use the same colours for painting the same parts of a sentence. Subject is always red, main verbs are blue, auxiliary and modal verbs are green. Thus my students know that in every question there has to be something green before the subject, while in positive sentensces green is either follows the subject or is absent from the sentence.
What's your name? My name's Mary. 
Can you swim well? - Yes I can. I swim really well.
