Carson Dellosa Education -20 to 20 Student Number Lines Misc. Supplies – Big Book, 15 January 2015

I had these laminated at my school and they are fantastic. My students got a lot of use out of them and it was a great tool for them to have.

My students used these so much and it meant they could all borrow a number line when they needed.

I bought these for my seventh grade students this year. We spend much of Unit 1 talking about the rules of signed numbers and this helps them visualize how numbers change when you add or subtract negatives and positives.Most useful is that it’s glossy and you can absolutely mark it with expo marker and it erases right off. When ordering numbers, many of my kids wanted to have out their lines.

I had mine laminated at school, my students are consistently making mistakes when they should not be. I am hoping these will help.

They are durable but could likely stand to be laminated. You can write on them with dry erase and it comes off pretty well. I love these manipulatives my high schoolers with disabilities who could quite fathom negative numbers being real, but this makes integers tangible
