Summer SAVY Session 5, Day 4, Dive Into Design
Today, we continue measuring using nonstandard and standard units by measuring our strides. We discussed how measuring height with non-standard units can be more difficult than length. Ask your child what they can use for height. We started to measure our own height and other items for our pool.
Lesson 10: accurate measurements require identical units, precise starting and ending points, no gaps, or overlaps in coverage, and partitioning of left-over (non-whole) units (measurement accuracy), and using what you know about an object may be helpful in making an educated guess about the numerical approximation of an object (estimation).
Lesson 11: the larger the unit, the smaller the number of units needed to measure a particular object; the smaller the unit, the larger the number of units needed to measure a particular object (inverse relationship between size of units and number of units), certain units convey what is being measure better than others (appropriate units), and certain tools work better than others to measure the same attributes (appropriate tools).
