Student Number Lines, -20 to 20

-20 to 20 Student Number Lines is a great tool for teaching students about integers. The number lines are clear to read, durable, has bright readable numbers, and can be used over and over. This is a GREAT purchase for teachers and guardians.

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

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

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.

Laminate these and they will last forever. My students love them.
