Connecting Subtraction to Addition

Written by Donna Boucher

Donna has been a teacher, math instructional coach, interventionist, and curriculum coordinator. A frequent speaker at state and national conferences, she shares her love for math with a worldwide audience through her website, Math Coach’s Corner. Donna is also the co-author of Guided Math Workshop.

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!

      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!
