Bright Creations37 Piece Magnetic Number Line Set for Whiteboard, Teacher Supplies, and Classroom - Magnetic Number Line Whiteboard Pack (-40 to 120) - Numberline for Classroom

I was so excited to get this and put it up on my whiteboard but I the box was missing one of the magnetic boards with the numbers -1 to -5

As a middle school math teacher these were a fantastic addition to my classroom. I have two 8 foot whiteboards side-by-side these are mounted on, which fits the strips from -40 to 50 across the top. So plenty of number line leftover to hang as needed. The bright green seemed like it could be a turn-off, but once I realized that made them visible from every corner of the room I understood the color choice. The kids like how accessible and clear they are to read, I love that I can use them seamlessly while teaching since they're in easy reach.In addition, most of my peers use the traditional "poster strip" number lines hung around their rooms. When I shared my newest purchase several of them pointed out something I, as a new teacher hadn't realized: taking down everything off your walls at the end of the year is a huge pain, and since these are magnetic they go on and come down without the need for any staples or tape!

I am SO glad I bought these. My students really enjoy using them to help with addition and subtraction of integers.

Magnet for easy hanging to a board but letters are super small...

I have a student who struggles with adding integers. This has been a great tool. I just wish the negative numbers also went to 100. We use it on the electronic projector board and it doesn’t appear to cause any damage.

Great visual for student to see positive and negative intergers. I like the fact it's magnetic therefore can be placed whiteboard rather than taping on the wall. Also , it goes past 20 in the negatives.

Sturdy and large enough to be viewed across the room! Easy up and moveable!

Excellent product! Perfect size and I love the dry erase surface.
