Hang this large wall number line along the very top of your walls. The space above each number is for stickers or dots. I used a different color dot to represent skip counting by 2s, 5s, 10s. When it was time to introduce skip counting with my class I let them pick which color we were going to use (sticker) to represent counting by 2s, 5s, 10s. Some numbers will have 3 dots or stickers. For example, the number 10 (it is a 2, 5, and 10) so it would have 3 stickers above it. Includes numbers 1-120.
