## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Lovely
  

*by S***D on Reviewed in the United States on 26 September 2024*

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.

### ⭐⭐⭐⭐⭐ 







  
  
    Helpful and flexible
  

*by K***J on Reviewed in Canada on 6 January 2019*

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

### ⭐⭐⭐⭐⭐ 







  
  
    Very useful for integer operations
  

*by D***A on Reviewed in the United States on 24 September 2020*

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.
