Spindle Box

The Spindle Box is introduced to the child once they are able to identify the numbers from 1-9. This activity is used primarily to show the child that numbers can represent a collection of separate objects. It is also where the quantity of “zero” is first introduced and where the realization comes that “0” to “9” are all the symbols needed for arithmetic. The Spindle Box brings the concept of numbers from an abstract place to a more concrete one, where the child can see and touch and truly internalize their meaning.

Addition With Number Rods

As an extension of the Number Rods activity, the child may be introduced to addition using the rods. The child adds two quantities together by physically placing the corresponding rods end to end. The child then counts out the quantities to arrive at the answer.

Skip Counting

The child begins by placing one of the chains from the bead cabinet, its corresponding tickets, squares, cube, and counter on their math tray. This activity allows the child to visually see what it looks like when skip counting. Indirectly, the activity prepares the mind for multiplication, squaring, and cubing.

The Mathematical Mind

Math is a life-long skill. We count objects, place rings of multiple sizes on dowels, sort objects into 2, 3, and 4 compartments, notice pairs of objects, and insert coloured pegs into numbered math boards. As the children differentiate patterns and notice sequences, we start to quantify objects, building the logical mathematical mind that will be further developed in Casa.

Math: The Dot Game

The Dot Game is one of the most advanced Casa math materials. The child must be very familiar with the hierarchy of the decimal system in order to process various mathematical operations. In particular, carrying over becomes visual and manual, which solidifies the child’s understanding.
