What does this worksheet teach?
⌄
Tally each digit in the first 100 digits of pi and draw a bar graph of the frequencies. The directions on the page read: Go through the digits one at a time and make a tally mark for each one. Count the tally marks to get each frequency. Then draw each bar up to its frequency on the graph. An answer key is included.
Can I use this exploring pi worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade number theory, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
