Van de Walle says it best: Subtraction as “think-addition” is extremely significant for mastering subtraction facts.
I just finished up a new product that promotes thinking of subtraction in terms of addition. It has cards like the one shown above for all the combinations for the numbers 5 to 10. I also made a freebie that has just the combinations for 5. Enjoy!

Thanks, Amy! Love in any and all locations is truly appreciated! Ha ha.
Thanks so much Donna! Great idea! Amy 🙂
My pleasure! 🙂
Loving this resource that helps my kiddos with such an abstract concept. Thanks a bunch for sharing.
Right, it’s really tough, but critical that they understand the connection. Lots of concrete experiences really help!
Thank you so much for the freebie! I just worked on this skill with my firsties and I think they got it…I think. 😉 Hopefully I got at least the foundation going. This freebie will certainly help my strugglers though. Thanks again!
