Peg Number Board
myminifactory
Children are taught how to link counting to the numbers displayed on a board. With 20% cubic infill, printing the boards used 67g of PLA, while each of the (15) pegs printed with 15% linear infill required only 22g. Since the cost per gram is $0.053, this print should amount to $4.72, significantly lower than the wooden version priced at $29.99 (https://www.discountschoolsupply.com/dummy-type-code/excellerations-peg-number-boards/p/15915?es=237530000ESC&gclid=EAIaIQobChMIiLfC8Pm-5QIV7R-tBh2omwHGEAYYASABEgIRQ_D_BwE). When counting objects, children are taught to say the number names in standard order. Each object is paired with one and only one number name, and each number name is linked to one and only one object. Children learn to understand the connection between numbers and quantities by relating counting to cardinality.
