Estimation

This week we worked a lot on our estimation skills.  Estimating is taking a thoughtful guess and it should be close to the actual number, but it doesn't have to be exact.  We learned that you can use a referent to help you.  A referent is when you look at what 10 or 100 of the object looks like and then use that to make your estimate. 

Mrs. Braybrook read us a couple of books to help us understand how helpful estimating is and how to make good estimates.

We also watched a short video and used a pretty cool website: http://www.estimation180.com/  So far, we've tried the activities from day 6, 7, 25, 26 and 27. 

When we estimate, we use our "Estimation Station" poster. 

Once everyone puts their estimate up, we can see who has the highest and lowest estimates and then once we find out the real number, we can see who is close.



It's really hard to make a good estimate, but with practice it will get easier!

We were wondering...

What strategies do you use for estimating?  Have you seen the books or website we showed you?

Happy estimating!
