Activity:Probing for Answers

One group begins by calling out the location of the 3 × 3 area they wish to probe, such as A-C, 1-3.

If the opposing group’s Master has a shaded square within the area called, they indicate this as a hit; if not, a miss. Draw an X in squares that are misses, and put an O in the squares that are hits.

It is then the opposing group’s turn to select an area to probe, which is then recorded as a hit or a miss.

Groups take turns trying to locate the opposing group’s shaded squares.


Do you believe they have gathered enough information to specify the exact shape(s) and

location(s) of the opposing group’s shaded object(s)?

What would help you define the shape and location of the opposing group’s shaded

object(s)?
