Uncanny Slate Mystery by Abbott’s(c. 1938)
The performer shows a slate, on which are drawn four horizontal chalk lines. The performer writes a prediction, places it a sealed envelope, and hands it to a spectator at the beginning of the routine. He then has four sets of numbers called by the audience and has a fifth spectator add up the total. When this figure is read, he asks the spectator holding the prediction to read it, and it is found to be the same figure as the total on the slate.
Easy to do and a different result is shown each time.
