About Accuracy and Approximation
How accurate are robots? Groups draw lines by moving robots backwards and forwards by one rotation of the wheels. Using the appropriate formula, they determine the percent error in the length of the lines in relation to the calculated...
Curated OER
Length
In this estimating lengths learning exercise, students observe problems with pictures and lengths and choose the length that gives the best estimate. Students solve 9 problems.
Curated OER
Estimating and Measuring
In this math worksheet, student estimate the lengths of a variety of objects. Then, students measure the actual length of each object.

Standard Units of Measure
Learners explore linear measurement. They choose appropriate measuring tools, measure three classroom items, and record their results. A class discussion ensues in which everyone decides the best way to present their data.
Curated OER
Estimate Length
Without measuring, can estimators determine which string is the longest? The shortest? There are two sets of strings here for learners to evaluate, circling the shortest in the first set and the longest in the second. Next, they eyeball...

Measurement: Finding Areas of Rectangles
Gardening geometers construct the formula for the area of a rectangle by viewing a video revolving around two young people, their lawn mowing business, and their need to charge by the square meter. A relevant real-life application lesson...
Curated OER
Length
Without using a ruler, learners estimate the relative length of various lines in these three scenarios. The first two are set up as maps, with learners determining the shortest and longest distances from one position to another. The last...
