This is what I have on my list so far ... Sharpie marker, whiteboard, whiteboard markers, dice, poker chips – 4 colors to make place value chips, flat square tiles, index cards to make number bonding cards, and sticky notes. I'd love to find one set of base 10 blocks.
In addition I've been scouring the Internet for engaging learning activities that focus on number sense. I've collected several thanks to the many math bloggers!
I also created an activity - a simple hundred board counting activity where pieces of the board are broken and numbers are missing. Students simply fill in the missing numbers. The focus is on counting by ones but also +10 and -10.

What are your favorite manipulatives for helping children with number sense? Do you have an activity to share?
