Second project - I've been using this version of Whole Brain Teaching scoreboard for 2 years now and LOVE it! I needed some new gems for my points. Just hot glued some magnets to the backs of these and ready to go. Make sure your magnets are strong enough to hold them on your ten frame. My ten frames are card stock and thick laminate and some of the magnets would tend to slide.
Third Project - I've already shown you the board, but didn't really address the technique used for the border. It's super cheap (FREE! You know that roll of paper all workrooms have) and super easy. Simply cut your strips of paper into whatever size you want. I think mine were around 4-5 inches wide. I accordion folded them. (Make sure you fold several together at one time to save a lot of time!) Next, simply wad up like you're going to throw it away. Unwad (is that a word) it and start scrunching and stapling.
