Went over the practice assessment and then took the real assessment covering explanation of volume formulas, applying volume, modeling with geometry, density, and angles of elevation and depression. Then thought about the famous problem posed by a mathematician named George Polya regarding points on a circle to motivate some discussion about circles.
Homework
- Keep studying formulas ahead of the EOC (see quizlet here: link)
- Next assessment is Monday 2/29
- For next class, watch and take notes on the video posted here:
Passed back assessments from Monday. Started by finishing the Meatball task involving volume. Introduced circles unit by looking at human's use of circles in art, design, and religious history throughout the centuries. Practiced circle vocabulary using whiteboards. Explored circle area and sector area using the Pizza task.

Opened class with a problem combining radius-tangent perpendicularity to find radius, area, sector area, and then composite figure area. Then solved the problem of how much it would cost to tile our classroom in pennies. Looked at differences in pure vs applied mathematics and how applied real-world problems can be very fun and interesting, but pure math problems can also be quite fun. Finished class with a task regarding relative size and percentage.
Homework:
- Assessment pushed back to Thurs/Fri of next week
