Procedure:

• Take the foam board: Begin by placing the foam board on a flat surface, ensuring it is stable and secure.

• Insert the small straw: Take the small straw and insert it vertically into the foam board, ensuring it stands upright and is firmly secured.

• Counting using small straws: Take the 10 beads you have and start counting them using small straws in groups of 5, with each small straw containing 2 beads.
  Follow these steps:
     a. Place the first small straw in the foam board.
     b. Add two beads to the first small straw.
     c. Insert a second small straw into the foam board next to the first one.
     d. Add two beads to the second small straw.
     e. Continue inserting small straws and adding two beads to each straw until all 10 beads have been counted.

  You should end up with five small straws, with two beads in each straw.

• Counting using medium straws: Repeat the counting process using medium straws, which can fit 5 beads each.
  Follow these steps:
  a. Remove the small straws from the foam board.
  b. Insert a medium straw into the foam board.
  c. Add five beads to the medium straw.
  d. Repeat the process by inserting additional medium straws and adding five beads to each straw until all 10 beads have been counted.
  You should end up with two medium straws, each containing five beads.

• Counting using long straws: Finally, count the 10 beads using long straws, which can accommodate all 10 beads in a single straw.
  Follow these steps:
  a. Remove the medium straws from the foam board.
  b. Insert a long straw into the foam board.
  c. Add all 10 beads to the long straw.
