- Presentation 1:

Two boards similar to the teen boards but with the numbers 10 – 90 printed on them.

Nine bead bars of 10

- Presentation 2:

The ten boards

A set of loose cards from 1 – 9

Nine ten bars

Ten unit beads

- Place all the beads at the top of the mat and then lay out the cards and boards in the same way as in the Teens Presentation.
- Read all of the numbers on the board with the child. (The child will probably say: 1 ten, 2 ten, 3 ten, etc.)
- Give the correct names (ten, twenty, thirty, etc) three at a time in a Three Period Lesson.
- Once the child knows the names for all of the numbers, read through them forward and then backward with the child.
- Emphasize that most of them end in “ty”. Look with the child at the numbers that do this: 20, 30, 40, 50, 60, 70, 80, 90. Tell the child that the “ty” tells us that there is a ten in the number. “40 tells us that there are 4 tens.”

Layout of the mat and materials ready tobegin the presentation: |

- Take out and place all of the beads onto the mat. Then place the 1 card to make 11 in the top slot.
- Place a ten-bar and a unit next to the cards. Have the child count and say how many there are.
- Ask if that is what the cards say. Yes.
- Have the child add on unit. Have him count the beads. (12) Ask if that is how many the cards say. No
- Have the child change the cards to read 12.
- Once you have made 14, show the child that we can simply point to the ten-bar and automatically know there are ten.
- Repeat until the child has formed 19.
- When you reach 20 (made by a ten bar and ten unit beads), have the child take a ten and exchange it for the ten unit beads bar to make 2 tens.
- Ask if the cards say 20. No. Take the 9 card out of the slot and ask if there is a place that says 20 (the second slot does).
- Have the child bring the two ten-bars down next to the second slot.
- Add a unit next to the two ten bars.
- Have the child count: 10, 20, 21.
- Ask if that is what the cards say. No. Have the child add the 1 card to the 20 to make 21.

Shows only half of the board - Repeat in this manner until 99.
