This two-minute PowerPoint slideshow will help your students improve their mental addition skills, adding multiples of 10 (Common Core 3.NBT.A.2). Use this as a warm-up at the beginning of a whole-class math lesson or right before recess. Place it on student-computers for extra practice or as a rotation during Math Centers. 24 different addition problems within 1000. Each problem appears for five seconds and students say the answer aloud before the next slide appears with the answer. Quick. No prep. Just click and it runs itself (fully-automated).
