1) This tree is 1,547 years old. It's hard to be certain about the exact age, so as a good scientist you need to approximate (or estimate) an age that rounds to the hundreds place.
What is this age?_________________
2) Assume this tree is 1,298 years old. What is the place value for the digit 9?__________________
3) What is the age rounded to the nearest thousand?__________________
4) This tree is 554 inches around (in circumference). How much larger is the place value of the first digit 5 compared to the second digit 5?
5) This tree is 320 feet tall. How many tens is this?_________________
For an interesting exercise that anyone can do, measure yourself and use the chart found here to find out how many of you it would take to build a tree this tall. If you would like to share your answers via comments below please feel free. It would take 81 Julias and 71 Graces. Anyone else?
