Mark, Recapture, Sampling
Learners conduct a simulation to explore how scientists estimate the size of animal populations. They analyze a random sample and then extrapolate those results to a larger population. Additionally, they will apply the principals of...
Balanced Assessment
Fermi Length
How long does it take to get to the end of a toilet paper roll? Pupils use their estimation strategies to find lengths of common items. For example, knowing the area of a roll of toilet paper, scholars determine the length of the full roll.
Balanced Assessment
Fermi Area
Discover creative ways to use surface area formulas. In the assessment task, scholars apply estimation strategies to determine surface area in non-routine problems. They consider surface area of kitchen sponges, rock salt crystals, and...
