There are no silver bullets in education, but the Multiplication Speed Ladder may be the closest thing to being a howitzer! The Multiplication Speed Ladder takes a different approach for learning multiplication facts and students, for some reason, buy into it. I have used the MSL at the 3rd, 4th, and 5th grade level and continue to be surprised at the focus and success of my students. I was a Title One teacher for years before I retired.
There is a challenge and a learning curve for teachers because they will have to model multiplication facts up to 12 on the fly. The results are rewarding!
