writing the numbers in order on the board seems to suffice to give the idea of what Rebecca and I going to teach. I'd say:"Let's count". This will give them me the idea of what I am going to teach.

With putting some guide lines on the board elve/teen/ty/hundred/thousand , students would distinct the differences more specifically...

Use titles as "elve","teen","ty","hundred","thousand" group on the board. This way would seperate 11 and 12 on the "elve" group, 13-19 on the "teen" category and "ty" 20-90 and so on. I chose this categories since students who are "false beginners" confuse the "teen" and "ty" group.

On a piece of paper, already fi(ai)v, fi(i)fteen, and fi(i)fty is printed. There will be given some WC and S drills on that. Second card is "th" sound plus the "teen" emphasis of "teen" group numbers.

I will now give individual examples on numbers. I'll write some digits on the board and they'll read it out loud.

Some matching sheets will be handed to the Ss. One example is already done which makes the instruction easy. Students do individually and the will be asked to check it in pairs. The answers will be checked by the teacher.

Students are given "cards" which includes some questions for numbers? ei: "How old is your mum/dad? What year were you born in? What's your favorite No.? Students will walk around asking their friends?
