In this error intervals worksheet, students are tasked with finding upper and lower bounds for rounded numbers and writing error intervals.
In Section A, students work with numbers rounded to different levels of accuracy, including: nearest integer, 100, 1 decimal place and 2 significant figures. For each rounded number, they must calculate the upper and lower bounds, then express the error interval in inequality form. This section involves several practical examples with varied levels of precision, reinforcing the concept of rounding and approximation.
Section B extends this skill by applying it to real-world scenarios, such as distances, altitudes, and measurements, where students must write error intervals based on given rounded values.
