68 Pieces Giant Magnetic Number Bonds Line Math Magnetic Counters Place Value Math for Kindergarten,Teacher Aid Dry Erase Whiteboard Accessories, Suitable for Children Over 5 Years Old

I use these in my first grade classroom to support our Ready Math program. As easy as it is to draw them, the magnets are a much nicer presentation. However, the material is flimsy and I would imagine it could tear very easily, especially if children used them. The small black circles are also hard to remove from board unless you have long nails. I would not purchase this product for child use, but it Is perfect for teacher usage.

Helpful to teach my 1st grader number bonds.
