JKHA fourth grade students have started to learn double digit multiplication. After reviewing the partial products method, the teachers introduced the traditional multi-digit algorithm. Students are continuing to use their estimation skills to determine the reasonableness of their answer. In addition to small group work, practice and games in class, students are now using Xtra Math at home to strengthen their multiplication fluency. In order to track their progress, students are given a 50-fact timed multiplication quiz at the end of each week.
