Dowling Magnets Magnetic Two-Color Counters (Red/Yellow, 1 inch Diameter Each), Set of 200. Item 732190. Counters for Kids Math/Math Counters for Kids/Magnetic Math Manipulatives/Montessori Math

These are fantastic to demonstrate working with integers. They do not stick to glass whiteboards - even the magnetic ones. The boards do not have enough metal for these to stick. They do work wonderfully on traditional whiteboards.

I wish they were slightly smaller. I wish they were slightly stronger. I wish they were slightly easier to pick up because they're so thin - but then they can't really be stronger because they're a little hard to pick up. We use them for loads of things. Chore chart you can just slap them over to mark what you've done. They're great for keeping score for things. Wouldn't do well trying to hold anything up, and great for counting, magnetic game pieces for connect four, and a good price for what you get.

I use these in the classroom when covering integers. The magnet is strong and the counters do not fall off the white board. They are a great quality and are built to last.

Working excellent for what I purchased for. I use for an ordering system. Yellow means to order, red means it is ordered. With the supply chain being messed up "from covid19," it's hard to remember what is on backorder this month. I just wish that the magnet was a little bit stronger.

The magnets are 2 sided and do stick. But the magnets are not very strong and do fall off easier than I would like.

These have worked very well for my kids with remote learning from school, since they are not allowed into the classroom because of the Pandemic. They have been a great visual aid and focus tool to help them with staying focused on the big white board in the wall and their personal smaller White boards they use to write on. Of course these are also great for other applications, like in the office meeting room or your cubicle.

These have worked great as visual manipulatives for my students (both middle schoolers and high schoolers) to teacher adding and subtracting positive and negative integers. They are magnetic so they work great while presenting to the class or I can let student individually use them while doing their indepedent assignments.

worked great for counting on a ten frame but the magnet is not strong enough to go through cardstock & laminate. I ended up adding sticky magnets to it.
