Describe a calculator activity for computational estimation practice - ANSWERSThe Range Game. Where
you pick a start number and an operation. Students will take turns entering the start number times a
number of choice, and then the = sign to try to make the result land in the target range.
Describe one teaching strategy that is important to know when teach computational estimation. -
ANSWERSUse appropriate language of estimation. This includes words such as "about, close to, just
about, a little more(or less). etc." Do not use the word guess as a substitution for estimation.
Describe one teaching strategy that you would want to avoid in teaching computational estimation. -
ANSWERSFocusing on answers. Instead you should focus on the students' computational estimation
strategies and methods.
Describe one way that students can respond to a computational estimation exercise without having to
actually give an estimate. - ANSWERSYou can allow them to undergo an activity which requires them to
determine if a particular solution is over or under a specific number
Why would you want to use an approach that students can respond to computational estimation
exercise without having to actually give an estimate? - ANSWERSit allows students to see that estimates
fall in a range and that there is no single correct or best estimate or method.
Explain why it is not a good idea to expect a specific answer to computational estimation problem? -
ANSWERSIt may result in students trying to quickly calculate an exact answer and then round it, which is
common strategy especially among poor estimators
What are three types of estimation - ANSWERSMeasurement estimation
Quantity estimation
Computational Estimation
, What is measurement estimation - ANSWERSDetermining an approximate measure without making an
exact measurement. For example, we can estimate the length of a room or the weight of a watermelon
in the grocery store.
What is quantity estimation - ANSWERSApproximating the number of items in a collection. For example,
we might estimate the number of students in the auditorium or jellybeans in the "estimation jar."
What is computational estimation - ANSWERSDetermining a number that is an approximation of a
computation that we cannot or do not wish to determine exactly. For example, we might want to know
the approximate gas mileage in our car in we travel 326 miles on 16 gallons of gas.
How is computational estimation different from other types of estimation? - ANSWERSComputation
estimation is actually estimating the outcome of a problem whereas the other types of estimation are
just trying to determine a single variable.
What is a front-end estimation strategy - ANSWERSEstimation that focuses on the leading or leftmost
digits in number, ignoring the rest. After an estimate is made on the basis of only these front-end digits,
an adjustment can be made by noticing how much has been ignored.
What is an example of front-end estimation - ANSWERSEx: price tags (398,4250,2725)- 0+4+2=6; about
6000 → 3+2+7=12 (12000 +6000=about 7300)
What is a compatibles estimation strategy - ANSWERSLook for number that can be grouped to make
bench mark values (10,100, 500).
What is an example of compatibles estimation strategy? - ANSWERSprices on menu (14,11,8,6,2,2) → 14
+ 6 = 20, 8 + 11 = 20, 20 +2 0 = 40 ,+5=about 45
What is a clustering estimation strategy? - ANSWERSestimate is needed for a large list of addends that
are relatively close
What is an example of the clustering estimation strategy - ANSWERSsongs on itunes
(68,52,81,55,57,60,71,63) → cluster around 60 → 8 ×60=480
