Meet L.J. the Number LINE JUMPER!
I give out these little smiley erasers to my students for Number Line Jumping practice. If you can't find the ones with little faces, the plain ones work too. You can even change them out for seasonal erasers. I like these because they stand up and stay securely on each number spot for students to record their answers.
I use them throughout the year as a little gift or treat. Like in a Valentine's Card!
