I also choose small steps to accompany my children to grow up healthily with real high quality. After all, many treasure moms say it is very easy to use. My child is almost three years old and has no idea about numbers. As a result, teachers patiently explained and guided by bottle caps, digital building blocks, various small peas in life and so on, and soon put those abstract numbers into concrete life. I can do some simple addition and subtraction slowly by myself.
