The purpose of this material is to associate the written symbol with the right quantity and to be able to build rods and/or numbers 1-10.
Number RodsMaterial: The Number Rods and one set of small wooden cards with printed symbols from 1-10.
Purpose: To associate the written symbol with the right quantity and to be able to build rods and/or numbers 1-10. Building up the different combinations to 10 gives an indirect preparation for addition. The taking away of rods gives the impression of subtraction.
In the first presentation, we build the rods from 1-10 in the same shape as the Red Rods and we also count each rod. In presentation number two, we let the child take the box with numbers/symbols and place them in order in front of the child. Then, we show a number and let the child chose the right rod from the shelf. In the extensions, we work with adding rods to each other by connecting them to make 10 and by taking away, we make 1.
