The dreaded 1.OA.4! The mystery of the missing addend has been causing my firsties some serious problems lately. I should say it WAS giving them problems. That is……until I searched for a solution on Pinterest. I searched and searched for an answer and I found one via Janet Wilkins. I have no idea who she is but she created a chant that made everything crystal clear for my class. My kiddos kept wanting to just take the two numbers and add or just guess at the missing number. Thank you so much Janet. Seriously people, here is what you need to conquer those dreaded missing addends. This will be a quick and easy center. I used counters, a part/part/whole mat, and this cute little chant that Janet Wilkins came up with.
