This PowerPoint follows skills taught in Common Core (College and Career) kindergarten unit 4 (counting and comparing numbers). Activities also appropriate for 1st grade. I've included calendar review. This PowerPoint incorporates a lot of active participation. The technology research has been done for you. There are slides with hyperlinks to videos about counting by 1s, 2s, 5s, 10s, comparing numbers, and using a 10 frame. I have also included hyperlinks to videos appropriate for brain breaks as needed. This PowerPoint has enough lessons, review, and videos for 4 to 5 weeks (all of Unit 4). It's also easy to edit as you see fit.
