But my child is dyslexic and highly visual. But I know that for mine it opened doors that had been closed before. This is exactly the same thing.Ĭammie, I cannot say whether lattice method is a good or bad thing or even just another way to look at math for your child. That is virtually impossible with more than five kids to a teacher. The others are just as valid, but require students to understand the concept not just perform a process. Schools in the US usually only discuss maybe two. There are six different ways to explain adding. He will not be able to apply it late in algebra or pre algebra. If he does not understand that, then none of the methodology matters. The only thing that matters is if your son understands what he is doing when he is multiplying multi-digit numbers. Grunt labor to beat the Russians.Īs for the IB program, it doesn't matter. The algorithm we use as the standard was only implemented during the Cold War to produce citizens of a work force who could quickly churn out answers with no need of understanding. Many lattice kids are doing the same thing, by some feel it is more difficult because they physically have to cross and see the repetitions of the multiplication.
They are merely performing without understanding. The standard algorithm is being pulled away from by some schools because kids have NO idea what it means. It is a visual representation of the standard algorithm. What is the point of learning lattice multiplication if:Ī) it doesn't make the underlying concepts clearerī ) it doesn't require the student to have an understanding of place valueĬ) it's going to be dropped down the road in favor of the traditional algorithm anywayĪs a math teacher, I find nothing wrong with it. Everyone complains about homework assignments where students are required to use lattice, and problems (with the correct answer) are marked wrong if the traditional algorithm is used.Īpparently the middle & high school math teachers request that students use the traditional algorithm, because it is simpler and quicker so there is also a widespread feeling among parents that all those years of lattice worksheets were a waste of time. Parents of bright students seem to be less opposed to it, because their children do better at juggling multiple methods and keeping them straight. Parents of struggling students say that their children have trouble remembering all the steps and/or mix up the steps between lattice and traditional. There is universal disdain for lattice (and other fuzzy, alternative algorithms). Lattice is taught in our local schools (urban, affluent, highly educated area).
#Lattice multiplication how to
Once they know how to correctly draw the grid, all they have to do is simply multiply single digits and then write that answer in a box. Most children understand how to use a basic grid, and because of that children succeed with this method. Yes, it does!!! And for that reason alone I’ve taught my students to do it! Benefits of Lattice Multiplication How about, does it help children solve a problem. It in no way, shape or form builds number sense.ĭoes it prepare a child to do mental math? Nope!!! Lattice multiplication….my one and only reason for liking it is I’ve seen children that haven’t been successful with any other method take off with this one.
