Item 215

Teacher:

So, I want to know how many tiles will you get?

Let’s see your own clay-sculpted snakes, how many tiles do you get when you compare a length of the snakes with the tiles?

Item 216

Student-8

One, two, three, four. Four…but.

Item 217

Student-7

How many? (Student-8 ask together with re-counting the tiles that her snake is laid on.)

Item 218

Student-1

I have four, but Student-4 has four and a half, half more than midpoint and almost five.

Item 219

Student-4

I’m almost five.

Item 220

Student-1

If I could sculpt more than this, I will equal to Student-4. If Student-4 use my tale to connect her snake, it’ll be five.
