Reply To: Lesson 1 – Which Is Bigger? – Discussion

[Kathleen Rushinsky]

Spatial thinking, or reasoning, involves the location and movement of objects and ourselves, either mentally
or physically, in space. It is not a single ability or process but actually refers to a considerable number of
concepts, tools and processes (National Research Council, 2006).

I was working with my 8th-grade Intervention students today on measuring angles. Many of them had difficulty figuring out which numbers to use on the protractor. We discussed how important is to decide on whether the angle is greater of less than 90 degress before we even put the protractor on the paper.
