  • Pick up a bottle with a 3-finger grip and remove it from the basket.
  • Place it on the table to the left. Continue removing the bottles one by one and arrange them in a horizontal line in front of you.
  • “Now let’s feel the thermic bottles.
  • Place the upper half of the inside of the fingers of both hands against either side of the bottle lightly.
  • Feel each bottle in a similar manner, pausing between each one.
  • Let the child feel the bottles.

  • Now let’s see if we can find a pair. Let’s find a match for this one.” Isolate the first bottle below.
  • Feel the control, then feel each of the bottles. Pause and bring hands together after feeling each one.
  • Move matching pair slightly out of line.
  • Feel the control again, then the matching bottle: “These two match, these are a pair.”
  • Move the pair to the left side and isolate a new control.
  • Randomize the bottles and then offer the child a turn.

  • After sorting the bottles into pairs as in the other Presentations, say to the child: “Let’s find which pair is the coolest. This pair is the coolest.”  Feel each pair and moves the coolest pair to the far left.
  • “Now which pair is the hottest? This pair is the hottest.” Feel each pair and move the hottest pair to the far right.
  • “This pair is warm.”  Move the remaining pair between the first two. Feel each again to check order. Offer the child a turn.
