I recently attended a presentation on open middle math. I loved it. and looking through the kindergarten problems this is the kind of stuff I will be working on with my daughters. they have quickly grasped the ideas of addition and subtraction and would find this a little more challenging before introducing regrouping.
Thanks for sharing this Heath. Glad you loved it.
where can I locate continued online education courses for kindergarten 5th grade and 10th grade for Ellsworth public schools? I have three grandchildren that need to continue their education during the school shutdowns.
4+6=10
2+3=5-5
i ment 2+3=10-5
2+2=5-1
5+3=9-1
it was good practices for my kids of all grad.Thank you !
4+4=9-1
4+2=9-3
2+6=9-1
4+2=9-1
