Regarding Michael Alison Chandler’s May 16 Metro story, “Lessons are multiplying,” on Montgomery County’s changing math curriculum:

I’ve been dismayed at how it is working out for my youngest child, an 8-year-old who routinely comes home discouraged by how easy his math problems are. Recently, he again was doing very simple problems such as “What is 14 - 9?” I inquired as to why, and I was told it is because the children need to learn how to better articulate how they know that 14 - 9 = 5.

I strongly encourage the county to revisit whether its new approach is working and to look for ways to consistently provide challenging materials to all of our children, including those with a natural affinity for math.
