Unit/Lesson Topic: Multiplication/Multiplying 2- and 3-digit numbers
Bean Pot Multiplication
Objectives: TLW practice multiplication of 2- and 3-digit numbers.
TLW use a calculator as a tool.
Overview: This lesson will be used for practicing the skill, not teaching the skill. The students will work in groups of 4. The set-up and assessment can vary depending on the teacher. You may choose to have the students work with partners instead of groups. You may choose to just observe the students or to use a checklist to assess and possibly even have students turn in their work for a grade. This particular activity would work well in a math center for enrichment as well.
Materials: Deck of cards for each group (A-9 only)
Chalkboards and Chalk (to write problems) or Dry Erase Boards and markers or printed sheets set-up for mult. problems
Bean pot (cup with dried beans) for each group
TTW introduce the objectives and review the skill of multiplying 2- and 3-digit numbers.
TTW introduce the game and review the directions (see below).
TTW model how to play the game with the help of a few volunteers.
TTW divide the students into groups of four. (It is best to have a fair system for dividing students into groups, such as colored stickers. Also, you can assign roles for the students, such as leader, materials helper, reader, and card captain.)
TTW observe and monitor as the students proceed in playing the game.
TTW adjust the game as needed according to the students’ needs.
TLW follow directions of the game.
TLW proceed with his/her role in the group.
TLW record his/her answers and check answers using the calculator.
Bean Pot Multiplication Directions:
- The card captain shuffles the cards and places the stack face down in the center.
- The card captain turns over 2 cards and every player writes those two numbers anywhere on their chalkboard/paper (in any of the 5 spaces for the problem).
- Then the other players take turns drawing the next 3 cards and every player writes in those 3 numbers anywhere for that problem.
- Everyone finds the product of his/her problem (without the calculator).
- When everyone is finished, they use a calculator to check the product of the person on the left.
- Everyone who solves the problem correctly may take one bean from the bean pot.
- The person with the largest product may take one extra bean.
- Erase boards or move to next problem set-up on paper.
- Continue play. The winner is the one with the most beans at the end of the game. (If using the printed-paper, you might have a certain amount of problems set-up. If using the chalkboard, you might have a time limit).
For students having difficulty meeting objectives
*Have them work with only 2-digit multiplication
For students exceeding the objectives
*Have them work with 3-digit and possibly 4-digit multiplication
TTW observe the students as they play the game checking to see if they are able to solve the problems and use the calculator as a tool to check the problems.
TTW use a checklist to assess each student. (optional)
TTW collect the papers to check for accuracy and completion. (optional)
