Today Aiden and I discussed the concept of volume as the idea of how much space a 3D figure can hold on the inside. We started by considering an aquarium with a trapezoidal base. Aiden and I had not discussed a trapezoid yet, so this gave us the opportunity to discuss it's properties and derive the formula for area. With visual support, I showed Aiden how if we cut off the trapezoid at one end, and added it to the other side, the figure would form a rectangle. We used the area formula for rectangle to the derive the trapezoid area formula. Then we took it back to the Aquarium and considered that in order to find the volume, we would need to multiply the area of the base times the height. We completed that problem, then I related what we did to all prisms. If we know the area of the base, then the volume can be found by multiplying the area of the base times the height. I showed him how this would be true for cylinders, cubes, and I even showed him a heart shaped box. We will practice more with this on Monday.
