Learning Objectives
Students will be able to quickly multiply two and threedigit numbers using multiplication strategies.
The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.
Introduction
(5 minutes) Pose an example multiplication problem on the board, such as 7 x 29.
 Ask students to name strategies for multiplying with their group.
 After 1â€“2 minutes, have students share out and make a list of responses on the board.
Beginning:
 Provide a bank of multiplication strategies for students to choose from as they discuss ways to solve the sample problem in their groups.
Intermediate:
 Give students a sentence frame to support the discussion: "To multiply 7 x 29, I would use the ____ strategy because..."
Explicit Instruction/Teacher modeling
(15 minutes) Review each of the following strategies for multiplying by modeling how to solve these equations: partial products, mental math, lattice, and traditional algorithm:
 Partial products: 5 x 64 = 5 x 60 + 5 x 4 = 320.
 Mental math: For 10 x 22 you could think aloud: "I know that when I multiply any number by 10, I just have to add the 0 to the end so the answer is 220."
 Lattice: set up the lattice squares for 3 x 76.
 Traditional algorithm: 4 x 57.
Beginning:
 Have students repeat the steps as you introduce them for each of the strategies.
 Allow students access to bilingual resources, such as online dictionaries or bilingual glossaries, for them to utilize as you teach the strategies.
Intermediate:
 Define any unfamiliar words in studentfriendly terms in students' home languages (L1) or in English (L2). Words to include are "multiplication," "strategy," "lattice," "partial," "product," and "algorithm."
 Have students share their background knowledge, even if incomplete, for all of the math strategies demonstrated.
Guided Practice
(20 minutes) Distribute the Multiplication Strategies Flip Books.
 Instruct students to fold these in half and cut on the dotted line to create the flip book.
 Review each strategy with additional sample problems.
 Invite students to the board to solve the problems.
 Students at their seats should follow along and record steps in their flip books.
Beginning:
 Assign students a supportive partner for the flipbook activity. Encourage them to discuss the problems they record in the book and the steps of each strategy.
Intermediate:
 Have students rephrase and restate the strategy processes as they come up to the board to work on an example.
Independent working time
(20 minutes) Review directions for multiplication musical chairs:
 Students will use scratch paper and clipboards or whiteboards and markers to rotate around the chairs.
 Give each student a starting number.
 Students will walk around while music plays and stop at the nearest chair when the music stops.
 Once they stop, they will look at the number on the index card on the chair and multiply their starting number by that number.
 The teacher will walk around to observe students' strategies and mathematical accuracy during this portion.
 The teacher can choose to identify "winners," or students with the largest and smallest products if desired.
 After the round, students use their products as their new starting number for the next round.
 Repeat for five to ten more rounds or as time allows.
Beginning:
 Allow students to solve the multiplication problems in the musical chair game with a partner.
Intermediate:
 Tell students to verbally share their multiplication strategy with a partner after they solve it.
Differentiation
Support:
 Give a lower starting number for multiplication musical chairs. Give these students the Football Multiplication worksheet for their assessment.
Enrichment:
 Give a higher starting number for multiplication musical chairs. Give these students the 3 Digit Multiplication worksheet for their assessment.
Assessment
(15 minutes) Distribute various multiplication worksheets to your students.
 Have students work independently to complete the worksheet as their assessment using their preferred multiplication strategy.
 Instruct students to label each problem with the name of the strategy they used.
Beginning:
 Give students fewer problems to work on as their formative assessment.
 Let students work with a partner and ensure they share their strategies verbally.
Intermediate:
 Ask students to restate the directions of the assessment to a partner.
 Have students work in a small teacherled group for the formative assessment piece.
Review and closing
(5 minutes) Have students write in math journals or on scratch paper their response to the following question: Which multiplication strategy works best for you? Why?
Beginning:
 Give students sentence frames to support the discussion:
 "My favorite multiplication strategy is ____ because..." "I like the ____ strategy because it is..." "I do not like any of the strategies because..." and "I'm still not sure of my favorite strategy because..."
Intermediate:
 Have students share their sentences with a partner before discussing in a whole group.
Guided Lesson: Multiplication and Division
Guided Lessons are a sequence of interactive digital games, worksheets, and other activities
that guide learners through different concepts and skills.
They keep track of your progress and help you study smarter, step by step.
Guided Lessons are digital games and exercises that keep track of your progress and help you study smarter, step by step.
There are many strategies that can be employed to multiply and divide larger numbers. Students will deepen their conceptual knowledge of multiplication and division, starting with visual models like arrays and diagrams.Then students will then move to more abstract calculation methods like partial products, the distributive property and standard algorithms.
