The card game Oh No! 99! is a keeper! It gives practice with mentally adding one- and two-digit numbers and with adding and subtracting 10 from two-digit numbers.

Read about how the game was used with second and fifth graders. 
This blog post resulted from an email exchange I had with Jill Downing, a Title 1 Educator with the Helena Public Schools in Montana. My recent blog about using the children’s book 17 Kings and 42 Elephants included a link to an article I wrote, “Using Math Menus.” Jill read the article and was interested in more information. Her questions pushed me to reflect on some of the nuts and bolts I use when organizing math menus. Here I share what Jill wrote and how I responded.
