I hope you are using the wonderful resources from The Math Learning Center. They offer innovative and curriculum based tools and resources for mathematics. Their tools are easy and fun to use and can be implemented into your lesson plans seamlessly. These resources are offered as Apps for IOS and web-based. Each App opens on a whiteboard background with the tools aligned across the bottom or side. There is an "i" on the bottom right that will give you step-by-step directions and explain what each icon does and how to use. I have listed just a few that are available. Click on "Open Web App" to go directly to the web-based app. For more apps, go to their website:
