Starry, a calendar.

Can we use it to practice the numbers?

Ok, what number is this?

5, f-i-v-e     

And what about this number Starry?

8,e-i-g-h-t.

What’s this number Starry?

10, t-e-n

And  this?

19, n-i-n-e-t-e-e-n

Now Starry, what’s this number?

You don’t know. This number is number 20, 2 and 0, 20, t-w-e-n-t-y

Look at these beads Starry! How many beads are on this string?

1-2-3-4-5-6-7-8-9-10, that’s 10 beads.

What about this string?

1-2-3-4-5-6-7-8-9-10, that’s 10 more.

Now let’s count to them together!

1-2-3-4-5-6-7-8-9-10-11-12-13-14-15-16-17-18-19-20.

So 2 tens is 20. Starry, 20 has 2 tens and 0 units.

Now look at these beads again, that’s 10 beads plus 10 beads and 1 single bead.

So 2 tens and 1 units. 2 and 1, 21, t-w-e-n-t-y o-n-e      21

Now 10 beads plus 10 beads plus 2 beads is 2 tens and 2 units. 2 and 2, 22, t-w-e-n-t-y t-w-o     22

Starry, these are 10 beads plus 10 beads and 3 single beads. 2 tens and 3 units, 2 and 3, 23, t-w-e-n-t-y t-h-r-e-e      23

And again 10 beads plus 10 beads and 4 single beads. 2 tens and 4 units, 2 and 4, 24, t-w-e-n-t-y f-o-u-r        24

And here are 10 beads plus 10 beads and 5 single beads. 2 tens and 5 units, 2 and 5, 25, t-w-e-n-t-y f-i-v-e     25

Next is 10 beads plus 10 beads and 6 single beads. 2 tens and 6 units, 2 and 6, 26, t-w-e-n-t-y s-i-x      26

What’s next Starry?

10 beads plus 10 beads and 7 single beads. 2 tens and 7 units, 2 and 7, 27, t-w-e-n-t-y s-e-v-e-n     27

Now how many beads Starry?

10 beads plus 10 beads and 8 single beads. 2 tens and 8 units, 2 and 8, 28, t-w-e-n-t-y e-i-g-h-t      28

And finally Starry, we have 10 beads plus 10 beads and 9 single beads. 2 tens and 9 units, 2 and 9, 29, t-w-e-n-t-y n-i-n-e        29

Now that you have learn the number from 20 to 29.

Let’s do an activity together!

Read out the numbers and spell them out.

2 and 5, 25 t-w-e-n-t-y f-i-v-e

2 and 1, 21 t-w-e-n-t-y o-n-e

2 and 7, 27 t-w-e-n-t-y s-e-v-e-n

2 and 3, 23 t-w-e-n-t-y t-h-r-e-e

2 and 9, 29 t-w-e-n-t-y n-i-n-e

2 and 2, 22 t-w-e-n-t-y t-w-o

2 and 5, 25 t-w-e-n-t-y f-i-v-e

And Starry, here are a set of numbers from 20 to 29 all the coaches of the train that are all jumble up, we have to put them in the correct order.

Shall we begin! Yes.

20-21-22-23-24-25-26-27-28-29

That’s was fast Starry?

There go the 20 trains.

Starry, the next time, you see the number 2 and 0 remember t-w-e-n-t-y

And what follows is 21-22-23-24-25-26-27-28-29.
