For Number Talks, use 2 digit by 1 digit and 2 digit by 2 digit. You could use a 3 digit number by a 1 digit number also. You can show partial products and partial division strategies to help build understanding of the traditional algorithm. Refer to the NBT progression document to see these strategies. In addition bring in the area model if needed. Students can use several algorithms to show fluency with multiplication. However, stay away from lattice methods.
