3 Digit x 1 Digit Multiplication

Grade: 4

*This is a math lesson I taught during my student teaching internship.

1. Start by having the student write the expanded notation of the 3 digit number across the top of the base ten block sheet (123 = 100+20+3). Then have them write the one digit number on the side of the base ten block sheet.

2. Have the students work across the base ten block sheet completing each individual multiplication problem (100x6, 20x6, 3x6).
