- Invite the child to work with the leaf-shape cabinet.
- Show the child where the leaf-shape cabinet is located on the shelf. When the child has made the selection of the material, begin with the third step after naming the material for the child.
- Indicate the procedure for removing and carrying the drawers: with thumb, index, and middle fingers, grasp the knob of the drawer and remove the drawer halfway. Then place a hand on each side of the drawer and remove it entirely from the cabinet.
- Carry the drawer to the rug. Place the drawer in the top left corner.
- Indicate the insets to the child saying, "These are the shapes that some leaves have. After I remove the insets, I will match the inset to the frame."
- Begin with the inset in the upper left and remove the insets proceeding from left to right. Grasp the knob of the inset with the thumb, index, and middle fingers of the dominant hand, and place them in a horizontal line below the drawer.
- With the subdominant hand, select the inset on the left, trace the edge of the inset with the index and middle fingers of the dominant hand.
- Select the matching frame and trace it with the dominant hand, moving clockwise. Place the inset in the frame.
- Continue in this manner with all the remaining insets until all the insest are returned to the drawer.
- Return the drawer to the leaf-shape cabinet in the manner described in step #3.
- Start the work in the manner described above through step #4.
- Carry the cards to the rug. Place them below the drawer.
- Select the cards of the solid figure and place them in mixed order in a horizontal line at the top of the rug.
- Select the inset in the upper left of the drawer and match it to the appropriate card. Note that the printed figure is hidded by the placement of the inset.
- Continue with all the insets, selecting insets from left to right, top to bottom of the drawer.
- Begin to the left, and move the card with the inset to the top and right of the drawer. Continue to move the remaining cards with the insets to the top in a horizontal row.
- Then return the insets to the drawer, moving left to right.
- Collect the cards by moving from left to right.
- Return the materials to the shelf in the manner indicated in #3.
