Q. I was wondering, how come we don’t see children being educated that on Purim they should also do Matonos Laevyonim and give money to the poor as they do with Shalach Monos? They don’t seem to be thought that in Yeshiva either. Why?
A. Poskim disagree. Kehilas Yaakov (quoted in Orchos Rabbenu 3. p. 51 maintains that if they have their own money, they should contribute as complying with the mitzva of Chinuch. Kovetz Halochos (16: 8) is of the opinion that since they don’t own their mony before Bar Mitzva, there is no Mitzvaof Chinuch.
Horav Shlomo Miller’s Shlit’a opinion is that if they have reached the Onas Hapeutos or age of being able to donate, they can be given money to contribute to the poor.
