The following power point has TWO activities for use on Pi Day! They are both fun and educationally enlightening for students!
* The first activity is a method I use for estimating the square root of a number by using a number line.
* Students begin the activity with a basic number to become comfortable with the process, and then they figure out the square root of pi using the same method of estimation.
* The lesson concludes with a third number to estimate the square root, simply for concept reinforcement.
* The second activity involves pi and a person's hat size. Yes, that's correct!
* The activity is followed by a series of 14 analysis questions that students answer individually, even though they work through the activity as a group.
* The analysis questions require students to write inequalities about their hat size as comparisons using "greater than", "less than", "at least", "at most", "no more than", "no less than", and "between".
* These are both fun and educational activities for students, and great activities for celebrating PI DAY, not to mention, reinforcing previously learned concepts!
* The lesson could most assuredly be concluded with a slice of pie from your local bakery!!!
Happy PIE DAY to you and your students!
