QUESTIONS AND ANSWERS:
I love you activity. Just a quick question. For enrichment, I wanted to change the numbers to a higher value and it will not let me. Why is that? I was looking for an activity to use on three different tiers. Thanks you!
I locked in the number line because I used a font that most people don't have.
Ok I just made another page that you can edit the numbers on. If you go to My Purchases and download the file again you will be able to edit the number line. You will have to unlock each number to do it though. If you need any additional help you can email me at firstname.lastname@example.org
