2 Pack -10 to10 Double Sided Dry Erase Number Line Board for Students，Teacher Supplies, Number Line for Classroom and Desk, Math Manipulatives for Math Center，High Quality Durable 12 x 4 Inch 0 to 20

Very sturdy. Great value for the money. Very easy to clean.

I use to this in my special education classroom and it is such a helpful tool. It helps the students remember the steps and work more independently.

Comes as a two setter front and back perfect for learning number lines same on both sides just make sure you clean if we’ll with cleaner soap or water paper towel or dry erase spray or it will stain with the blues or colorful markers . But perfect tool easy to learn and help a child

We use these for homeschool math practice with some washable dry erase markers. They clean easily, are very durable, and do the job! They are also a great size, especially for kids!

I've used smaller versions of these in my classroom and wish I'd had this excellent product. Space to write a number sentence, larger numbers BENEATH the line, and kids rapidly learn to "jump" backward and forward to + & -. So much help building understanding from the concrete to the abstract! And being able to write that equation is imperative.

Great for kids.

These are not boards like you would think for the classroom. They are made of thick-ish plastic and arrived slightly bent. My students won't care but it kinda bothers me. Will update to see how they hold up in my resource classroom.

I am retired and use these for tutoring. The kids really like them. Of course, expo markers still leave a stain but that's to be expected. I highly recommend these.
