Teach Me Tuesday—When you were learning multiplication facts, did you have trouble remembering some of the bigger facts, like 6 x 8? Back in the ‘old days’, facts were learned through drill and kill. There was very little understanding involved. However, that is no longer the case. Students are now encouraged to use strategies to learn their facts. What exactly does that mean? It means that students use facts they know to help them understand facts they don’t. This Bump game focuses on the 2s, 4s, and 8s. These facts are all connected by the doubling strategy.
Students usually master their 2s facts fairly easily, because they are closely connected to addition. That is, 2 x 4 is the same as 4 + 4. The 4s facts are double the 2s facts. So if students know that 2 x 4 = 8, they can double that to find 4 x 4= 16. Extending it even further, the 8s facts are double the 4s facts, so 8 x 4 is double 16, or 32.
