12 Pieces Slide and Learn Number Line Positive Integers Number Lines 21 x 3 Inch Number Line Focuses on Numbers 0 to 30 for Kindergarten School and Home

The reviews on this made me giggle. I have a first grader, she doesn't have a hard time maneuvering the slider, it hasn't torn, etc. This is a great tool to use for at home schooling. It's hard to please everyone, they want the most flawless product - that doesn't exist. This is as good as it gets. Highly recommend.

Very flimsy the bear or cat that you put on the number line is very flimsy Can easily tears

I bought them and then laminated them, they are holding up for now. they are made of cardboard so if you do not laminate them the will get messed up.

I got this for my students. I let them choose how the set was. It worked great on helping them be independent on math worksheets

I had to return these. The quality was not good and they never would have held up in use.

I like this tool for learning math and thinking about addition and subtraction.

Very useful

These are great number lines that are for your tactile kiddos. The durability and sturdiness could be better, so I wouldn't leave them on desks, but rather...use them as needed.
