This is an interactive flipchart we used with our second grade classes to teach them how to use the hundreds chart to add and subtract quickly. This was a great activity to help our students explore moving up and down the hundreds chart by tens as well as laterally by ones. We used this flipchart to model whole group and then our students worked on completing the flipchart individually on their digital devices. The great thing about this flipchart is that you can always duplicate the pages to add more problems! Enjoy!
