Finite word lengths introduce quantization error in fixed-point systems. Truncation quantization causes a larger maximum error and a negative bias compared to rounding, but is easier to implement in hardware. Similarly, wraparound overflow is typically worse than saturation, but also requires more hardware.
Students will identify how technology has changed in an occupation over time. This is also an introductory rounding/estimation lesson using addition of money.
Teachers can use this free online resource to help students discover how rounding is a process which produces another number that is close to the original number. The activity starts with an animated lesson showing how to round numbers up or down to the nearest rounding number. Students can then explore rounding with a virtual manipulative, and finally test their understanding with some questions.
