This pdf includes one center for multiplication. I used this in correlation with the NYS Module 3, which is about multiplication and division. These word problems are applicable for the lessons where two-digit numbers are being multiplied by two-digit numbers. It is a continuation from my previous center which began multi-digit by one-digit multiplication. These are aligned with the common core state standards 4.NBT.5, 4.OA.2, and 4.OA.3. These could be used in other grades as well to increase fluency, challenge students in younger grades, or to help students who struggle in higher grades.
In this center, students need to read through a word problem and determine how to solve it, using multiplication. There are challenging ones, which are differentiated based on a lighting bolt so that students can easily find the difficult ones.
This center has 20 cards, which are numbered.
