Lesson Plan
Multiply the fun with this lesson that can be used to reinforce multiplication of 2- and 3-digit numbers. For example:
52 x 29 = 1,508
381 x 66 = 25,146
408 x 164 = 66,912
Begin the lesson by printing a sample multiplication format on a board or chart. For example, you might share this format for multiplying a 3-digit number times a 2-digit number.
____ ____ ____
X ____ ____
-------------------------
Show students a deck of cards that has been shuffled after removing the aces, 10s, and face cards. (All that remain are cards numbered 1 to 9.) Select the top five cards from the deck. Use the cards drawn to create a multiplication problem. For example, if the five cards drawn are the 4, 7, 2, 2 and 9, then use those cards to fill in the spaces in the format pictured above.
__4__ __7__ __2__
X __2__ __9__
-------------------------
Invite a student(s) to come to the board to perform the multiplication operations.
__4__ __7__ __2__
X __ 2__ __9__
---------------------------------
4 2 4 8
9 4 4 .
---------------------------------
1 3, 6 8 8
Provide some additional sample practice for students. Then you might divide the class into two teams or arrange students into pairs. If you arrange students into pairs, give each pair of students a deck of playing cards. Have them remove the aces, 10s, and face cards and shuffle the remaining cards. Then instruct them to draw four, five or six cards and solve problems on their own.
Depending on the skill you want to reinforce, students might solve 2-digit x 2-digit problems (draw four cards), 3-digit x 2-digit problems (draw five cards), or 3-digit x 3-digit problems (draw six cards) – or a mix of the three formats.
Students might take turns solving problems; while one student solves the problem by hand the other can use a calculator (or an online calculator) to check those calculations.
Assessment
Provide five similar sample problems for students to solve on their own. Students who get at least four of the problems correct will have mastered this skill.
