I know, I know... the cardinal rule of blogging is not making two posts in a day. And I'm sorry! But I promise this is worth it!
I was outside reading more of my Debbie Diller Math Work Stations book and I came across an activity where students record 1 more, 1 less, 10 more, and 10 less for the day's number on a section of a 100 chart and I knew I HAD to make one for my calendar math board, as this is something that is always challenging... and I knew I HAD to share it with you lovely folks!
So, here it is! Please forgive me for making two posts today... I committed that offense many times last month before I realized what a taboo it is! Thanks for the comments too! :)
I've recently added a super fun way to practice place value to my TpT store... a base 10 block classroom or hallway hunt!
