Paper packet. Every task here also exists on screen, where it is checked automatically; answers written on paper are not assessed by Nydus. When you are back at a device, enter your answers there.

1. What you will learn

Today we read 9 and 10, matching the entire numeral to the amount it names.

2. Written-number words

3. One amount, two digits

Nine is written 9. In this print it has a loop at the top and a line going down. Ten is written 10: a 1 followed by a 0. Read those two marks together as ten. Do not count the written marks to decide how many objects the numeral names. A label with two marks can describe ten objects.

4. Check with a frame

Nine fills five spaces in the top row and four in the bottom. One space remains empty. Ten fills both rows completely. Adding one dot to nine makes ten. When you write the label for ten, keep both digits in order. Leaving out the zero changes the number; turning 9 around does not keep its meaning either.

5. Ticket maker

Make nine pretend tickets and label the bundle. Add one ticket. Count again and replace the old label. Explain why a changed amount needs a changed label.

6. Name a full frame

1. 

   Count both rows.

   Five and five: ten.

   Every space has a dot.

2. Write its whole label.

   10.

   Both digits name this amount.

7. One empty space

1. 

   Count filled spaces.

   Nine dots.

   One box is empty.

   Write the matching numeral.
