Question

When do we estimation in general and why even when tools of measurement are available? support your answer​

Answer 1

Answer:

Measuring with a standard unit (beginning with an unconventional unit such as a toothpick) will give students a base for estimating measurement. Using the same unit to measure different things will help students begin to visualize how many “toothpicks” it will take to measure a length of something. When students are able to visualize in this way, they are able to make reasonable estimations. (Note: You’ll need to decide whether to use the term “estimate” or “guess” throughout this lesson, depending on the level of your students.)
