Small Bead Frames: Numeration Based on Position

Age
6-9.

Materials

 * Small bead frame form for each child.

Presentation

 * 1) Moving one unit bead to the right, the directress counts one and writes the digit on the form.
 * 2) The numeration continues: move a bead, say the number, write it down.
 * 3) As the tenth unit bead is moved forward change these ten units for one ten bead forward. Write the digit 1 on the blue line.
 * 4) Move another ten bead forward- 2 tens and write a 2 in the column.
 * 5) The numeration continues in this way up to 90, changing 10 tens for 100.
 * 6) Finally the numeration ends at 1000.
 * 7) This is controlled by 28 lines on the form.
 * 8) At the end fill in all of the zeros to bring into focus the passage from one hierarchy to the next by the placement of one more zero each time.

Control Of Error
Directress.

Points Of Interest
Each time the child forms a number he will recall the formation 10.

Purpose

 * To recall the concept of changing from one hierarchy to another from the decimal system operations.
 * To help the child to fix the places which correspond to each hierarchy.
 * Familiarization with the bead frame
 * Knowledge of the passage between hierarchies

Variation
Formation of Numbers 1) The teacher forms a number on the frame. The child reads it. 2) The child reads a number from prepared cards and forms it on the frame. 3) The child forms any number on the frame, reads it and records it on the left side of the form used earlier for the presentation.
