Description: In this deck, students will practice putting 18 and 19 in their heads and count back on their fingers to find the difference. I have a free Google Slides to go with these Boom Cards available for download on my Facebook Page "Engage and Inspire with Mrs.Schneider" or on my Linktree. There are 20 cards.
