Kids learn to do things like cut apples, with a regular knife. At age 3. I will never forget one parent’s reaction. She was horrified and asked us “won’t they cut themselves?” My partner: “yeah, usually.” You could see her mentally nope out. That is a great viewpoint into Montesorri’s philosophy: that small kids are way more capable in many regards than adults assume.
There is also almost no need for a traditional gifted program because as kids finish materials nee ones are available. Grades are very fluid in a Montesorri classroom and kids have the freedom to explore everything. I think it works well for most children. Better by a lot for most kids compared to the traditional systems of public school.
So you give them a specialized environment and let them loose and then follow their interests, “follow the child” as Montesorri said. Then you guide them. The materials are designed to make it easier for kids to do on their own, but they also get plenty of help.
It is a very uncomfortable notion for many parents, but my daughter is a great example. She is 10 and easily doing work several grades ahead in topics that she excels at. No need for a gifted program really, the materials and support system is there to let all kids work at their own pace.
