Students in 3rd grade today reinforced what they are learning in math with breadboards. A breadboard is a piece of plastic with holes in it that are electrically connected in a predicable pattern. This allows us to build a complicated circuit without any soldering. Today students demonstrated their ability to use the coordinate grid to layout wires and a 5v power supply.
Parents: as a check for math understanding from the lesson today you might ask your 3rd grade student “What is three times grey?” If your child replies “One Dollar and Fifty Cents” then they are correct. We had green wires that are ten units long and grey wires that are five units long. We used the green wire to represent one dollar. This lesson sets us up for more complicated circuits in future weeks.
