Note for parents and teachers: Though this game helps children practice estimation, it does not teach strategies for estimation. Before having your child or student play this game, you should discuss estimation strategies with them. Read the section titled "Estimation and Children" for an estimation strategy children can use.
Guess It! is a game which will help children develop their ability to make approximations and estimates. In this game, Professor Puzzler will show the child a group of objects scattered randomly on the screen. The child will have a few seconds to look at the objects; there will not be enough time for the child to actually count the objects.
After a few seconds, Professor Puzzler will remove the objects, and then give the child a multiple choice answer selection. The child must click on the answer which best approximates what the child has seen on the screen.
For some questions, Professor Puzzler will scatter two or more types of objects on the screen (for example: red dots and blue dots) and ask the child to tell whether there is more of one kind or the other.
The child will also encounter objects of different sizes, which will add a bit of extra challenge to the question, since objects which are larger take up more area on the screen, even if there aren't as many of them.
