Snake Game for Addition
Snake game for addition, learning to calculate with Montessori material
Including bead material and storage boxes
The snake game is a popular Montessori bead material for children to practice addition. Especially the transition between tens can be shown tangibly by simply counting and swapping.
The numerical values 1 to 10 in the form of coloured number bars are initially placed next to each other as an addition problem. Then the swapping begins. For every full 10 counted, the child puts the coloured individual sticks aside and replaces them with a golden ten stick. It proceeds in this way until no 10 is full and replaces the remaining individual rods with black and white exchange beads. When there are no more coloured pearls in play, the task is finished.
Use, advantages, areas of application for this Montessori material:
-
- Simple addition problems with any number of numbers, also with the transition to tens
-
- Memorization of the number combinations that add up to 10 (2 + 8, 3 + 7, 6 + 4 ...)
-
- Montessori material from 5 years
-
- Logical representation of the addition with the pearl material
Scope of the Montessori learning material:
1 wooden tray, approx. 33 x 12.5 x 4 cm
, 1 wooden box each red, black, gold, approx. 10 x 10 x 4.5 cm
5 coloured pearl stairs (5 x pearl sticks 1 - 9)
23 golden 10-pearl rods
1 pearl staircase black/white
pearls: diameter approx. 7 mm
Instructions for addition with the snake game
The snake game is provided, and the black and white exchangeable pearl staircase is laid to the side. Then the adult assigns any task (in a queue) with coloured bead sticks. For example, he lays the following row: 3 + 8 + 2 + 4 + 6 + 7 = in the direction of writing a 3-bead bar, next to it an 8-bead bar, a 2-bead bar, etc.
Now the individual beads are counted aloud one after the other until the value 10 is reached:
one, two, three, four, five, six, seven, eight, nine, ten, STOP. Ten coloured pearls are exchanged for a golden ten-pearl rod. This is placed in the place of the 3 and 8 rods. Now there is still one pearl left of the 8-piece. The 3 and 8 rods are put aside (possibly in a bowl) and a single pearl is placed in the line from the black and white exchange pearls. Now the counting continues (the single bead, the 2 bar, the 4 bar and the 6 bar). Every single pearl is counted out loud until the value 10 is reached. The coloured pearl rods are put aside again and replaced by a gold 10 rod. The remaining 3 pearls of the rod of 6 are replaced by a rod of 3 of the exchange pearls.
The result of the calculation can now be read off easily using the 10 bars.
If there are any pearls left over from the last pearl
bar, e.g. 8 + 5, the remaining 3 pearls are replaced by the black and white exchange pearls.
