If you told a class that your sister was 3 metres tall, would they believe you?
This set of statements about measurements is intended to help classes consider what's reasonable and what's not. They're intended to be discussed as a class, rather than worked on individually, and provide a great focus for discussion.
We spend a lot of time teaching measurement in math and, even with our best intentions, students can sometimes feel bogged down in numbers and abstract concepts. These sheets are a way to:
a) Take a break from students doing calculations and providing numerical answers,
b) Bring the subject firmly into the real world, and
c) Provide a little light relief and humour.
While students work on their understanding of measures, a critical aspect is to be able to spot a measurement that is clearly wrong. A calculation error leading to an answer of the school being 124 cm high should make them realize that something is not right, and these worksheets are to help students to recognize these situations.
Each sheet in the pack covers measures of length, volume, capacity, mass (weight) and time. The most common measures are used more than once. The pack includes four sheets:
Metric Measures - SI units, plus standard measures of time.
Imperial Measures - Measures are approximate enough to be applicable in either Imperial or US versions of units.
Mixed Measures - A mix of the most commonly used measurements from both systems.
Mixed Measures 2 - Includes some additional measures such as area, and compound measures such as kph (kilometres per hour)
These sheets are interesting and fun, and include answers and teachers' notes. The .zip file contains both a .pdf file and a word format (in a very old version of Word)
