The lattice method can be tricky but this guide will help. Above all, this method improved self-esteem and self-confidence in the students. In third grade your child will be learning different methods of multiplying double digit numbers. Students obtained much higher scores in the test with the Lattice Method than with the traditional way of multiplication. Overall, statistically significant differences between the two tests were found on the pre-test (significant at the 0.01 level) and the post-test (significant at the 0.05 level) on the basis of the formula of Chi-square. There are also several practice worksheets that explain how to use the lattice method to solve multiplication problems. This page contains lattice grids of various sizes. In addition, the method was used to teach decimal multiplication to students with learning disabilities very effectively. Lattice multiplication is a fun way of solving long multiplication problems with a grid. It was also found that students were not able to multiply two or three digits in the traditional way, but they were able to multiply two or more digits with the Lattice Method in accuracy ranging from 90% to 100%. Proper instructions greatly reduced the repetition of student errors in multiplication. The method ensured that students with learning disabilities avoided misplacing place value and other errors in multiplying algorithms. Special education teachers who used the method to teach their students multiplication with whole numbers and decimals achieved great success in their classes. In the study, students with learning disabilities were able to do multiplication by the traditional way only with 15% accuracy, but they skillfully used the Lattice Method to multiply more than 2 digit numbers with more than 97% accuracy. The common errors made by learning disabled students in multiplication with whole numbers were analyzed. Any subset in a chain is a sublattice of it (not necessarily convex). The purpose of the study was to help teachers understand the importance of using the Lattice Method in teaching multiplication with whole numbers and decimals to students with learning disabilities. An example of a sublattice is any one-element subset of a lattice other examples are: an ideal, a filter and an interval.
