Kelley Hall - Duff Elementary
This app found in the iTunes app store provides a variety of math tools to be used in the classroom. I teach 2nd grade, but this could be used for many different elementary grade levels. It includes a 100s chart, number lines, ten frames, arrays, money, a fraction kit, number houses, tether math, number tiles, and a math challenge game with many levels of difficulty. In my classroom, I was able to use this app for whole group instruction and guidance, partner activities, table activities, and independent work. I can quickly scan the room and see if the students are mastering the skills or if they require further instruction.
Oh, and it's FREE!
