In this Best Practices Weekly video, this teacher reviews an article from Teaching Children Mathematics on teaching measurement. Three strategies are reviewed: The Button Task, The Foot Task and the 1 inch Squares Task. This is a great resource to he...lp teachers improve their mathematics instruction in the classroom.

Learn how to use the concept of similarity to measure distance
indirectly, using methods involving similar triangles, shadows, and
transits. Apply basic right-angle trigonometry to learn about the
relationships among steepness, angle of elevation,... and
height-to-distance ratio. Use trigonometric ratios to solve problems
involving right triangles.[more]

Learn about the relationships between units in the metric system and
how to represent quantities using different units. Estimate and measure
quantities of length, mass, and capacity, and solve measurement
problems.

Investigate the difference between a count and a measure, and examine
essential ideas such as unit iteration, partitioning, and the
compensatory principle. Learn about the many uses of ratio in
measurement and how scale models help us understand r...elative sizes.
Investigate the constant of proportionality in isosceles right
triangles, and learn about precision and accuracy in measurement.[more]

Explore what can be measured and what it means to measure. Identify
measurable properties such as weight, surface area, and volume, and
discuss which metric units are more appropriate for measuring these
properties. Refine your use of precision in...struments, and learn about
alternate methods such as displacement. Explore approximation
techniques, and reason about how to make better approximations.[more]

Please make your comments on categories positive, and not just negative.

People work hard on educational categories, and we want to encourage them to make more!

Profanity (curse words), sexually suggestive remarks, and other such obviously inappropriate comments
will be deleted immediately, and are grounds for immediate expulsion. Remember, children use this website.

Personal criticism on project forums and in video content is not allowed and will be deleted immediately.
Any violations of this rule could result in expulsion from the project so please, no insults or other negative
personal remarks.

Very harshly-worded criticism of content will also be deleted promptly. Please use your vote to express your
harshest feelings. Repeated violations of this rule can result in expulsion. If you must criticize another
person's hard work, then be nice about it.
