Multiplication Bingo: Two-Digit Numbers

Explicit Instruction/Teacher modeling

• Write a two-digit by two-digit multiplication problem on the board. For example, 13 x 11 or 15 x 10. Write the problem vertically.
• Model solving the problem using a few different methods. Some methods may include traditional, lattice, illustrations, repeated addition, etc.

Guided Practice

• Write another two-digit by two-digit multiplication problem on the board.
• Ask the students how they would solve the problem.
• Allow a few students to come up to the board to share strategies they would use to solve the problem. Student strategies may include illustrations, equations, the lattice method, arrays, or area models.
• Explain to the students that they will each have a whiteboard and a marker to solve the multiplication problems.

Independent working time

• Pass out the bingo boards, whiteboards, and markers.
• Shuffle the calling cards.
• Pick up a card, and read the equation. For example, "What is ten times ten?" Write the equation on the board.
• Give students a few minutes to solve the equation.
• Call on a student to give the answer. If the answer is correct, write the answer on the board. If the answer is not correct, help the student to solve the problem correctly. Students should find the answer on their boards and cover it with a counter.
• Continue calling out the equations until a student calls bingo.
