<Tab/> <Tab/>I interviewed both my children separately with the conservation of number tasks. I used 14 pennies; 7 pennies in 1 row and the other 7 pennies in a row spaced farther apart than the first row of pennies. First, I interviewed my 4-year-old daughter; I asked her if there are the same amounts of pennies in both rows. She did not ask me anything she just began to count. …showed first 75 words of 502 total…

…showed last 75 words of 502 total…could tell me there was and that the glassed were shaped differently. Therefore my daughter had mastered conservation of number but not liquid and my son has mastered both. In conclusion, I could not asses a child on these tasks and give a correct and proven stage he or she is in according to Piaget. Piaget also cautioned that although all children pass through these stages, they do so at their own rate (text page 21).
