A binary-numbers lab for ages 8-13 explaining that computers count with switches that are off (0) or on (1). Bit Switches presents five switches worth 16, 8, 4, 2, 1 with a live decimal total, the addition spelled out, binary chips, Make-7/19/30 challenges, and a finger-binary hand that counts to 31. Decode the Number runs 10 binary-to-decimal rounds growing from 5 to 8 bits plus 4 build-it reverse rounds. Secret Letters encodes A=1 to Z=26 as binary groups; kids decode six words (CAT, DOG, SUN, CODE, HI, MAP) and encode their own short word.
