In class, Dr. Heyman discussed research on "the min strategy." This strategy is:

a. The tendency to ignore the smallest number when estimating the answers in addition problems (for 30 + 2, ignoring the 2 and estimating that there are 30) b. the tendency to decompose numbers into smaller parts and then recombining them to make them easier to add (for 17+2, changing the problem to 10+7+2, and then to 10 + 9). c. the tendency to start with the smaller addend and then count the other addend (for 3 + 5, count start at 3 and count 4,5,6,7,8) d. the tendency to start with the larger number and then count up the number of times represented by the smaller number (for 31 + 2, starting at 31 and then counting 32, 33)
