  2. The 2nd grade students from Monte Flor already solved the first problem, about the wheels.
    Most of the pupils reached the solutions and after that we discussed what they did and how they did it.
    Most of them drew the cars to answer the 1st question and counted the wheels, reaching 96 wheels. Some of them did 4 + 4 + 4 twenty four times and reached the same value.
    To solve the second part of the problem, most of them drew 96 wheels and then made groups with 2 wheels each. Then, they counted the groups and reached the value of 48 bicycles. One girl wrote: if a bicycle has half wheels a car has, then we only need to split 96 in half. She also reached 48.
    Thank for your problems, next week we'll solve the fish tank problem.
