Materials
4 sets each of small, medium, and large nuts and bolts
3 pieces of 2" x 4" (5 cm x 10 cm) wood, each 16" (40 cm) long Super glue RulerInstructions
1. Glue the top of a large bolt 2" (5 cm) from the end of one of the 2" x 4" 
boards. 
2. Glue three more large bolts to the board, at 4" (10 cm) intervals. 
3. Repeat this procedure on another 2" x 4" board, using four medium-size 
bolts. 
4. On the last 2" x 4" board, repeat the process again using four small bolts. 
5. Allow the boards to dry. 
6. Provide a board and the correct size and number of nuts to a child. Consider 
the child's fine motor abilities when choosing a board for her to use the 
larger the bolt, the easier it is for a child to manipulate. 
7. Show the child how to manipulate the nut and bolt together and encourage 
her to practice her fine motor skills. 
More to do 
Make a board with assorted bolt sizes. This will challenge children to problem 
solve as they locate and match the correct nut and bolt combinations.
