**Great fun for second grade classrooms!!!
This is a powerpoint designed to be used with the whole class. Students should have their own 100 charts and a counter so they can follow along and be engaged. The powerpoint shows that counting ten more on the hundred chart always results in landing on the number directly below the square where you started. It progresses to adding +20, + 30, etc. For the last slides, students should have a paper copy of a 100 chart and a crayon. They are directed to color in various numbers (+10 or +20, etc.) and when finished, the squares they colored form a big number "10."
