Title

Comparing Multiplication Facts (Hey Tocayo!)

Lesson Objective

Students will interpret a multiplication equation as a comparison and represent verbal statements of multiplicative comparisons as

multiplication equations. Students will practice finding factor pairs for a whole number in the range 1-100. Students will recognize that

a whole number is a multiple of each of its factors. Students will determine whether a given whole number in the range 1-100 is a

multiple of a given one-digit number.

Background Information for Teacher

N/A

Student Prior Knowledge

Student should understand factors.

Materials:

● A whiteboard

● whiteboard marker

● A multiplication chart (attached if necessary, Step 3)

● A multiplication worksheet (Step 3)

Step 2: Teach Lesson

Teacher explains that in some Spanish speaking countries, when 2 people have the same name, they often greet each other with the

word “Tocayo” (Toe-KIE-yo) for a boy, and “Tocaya” (Toe-KIE-ya) for a girl. Explain that in many languages a lot of names have

many nicknames. For example, the name Kathryn could have a nickname of Kate, Katie, Kathy, Kat, Katrina, etc… but she is still

Kathryn. So if a “Kate” meets a “Katie,” she can still say “Hey Tocaya!”

Explain that in multiplication, whole numbers often have multiple factor pairs. So if “2 x 10” meets “4 x 5,” they can say “Hey Tocayo,”

because they are both actually “20.”

Show the multiplication chart (Step 3). Point out to the student that there are many numbers that appear many times as an answer

with different factors, for example the number 12 appears 6 times!

Have the student name the different factor combinations that have a product of 12 using the multiplication chart and write them as

follows.

○ 2 times 6, 6 times 2, 1 times 12, 12 times 1, 3 times 4, and 4 times 3

Instruct the student to go to the whiteboard and whiteboard markers. Tell the student to look at the multiplication and find products

that appear multiple times on the chart and write all the factors from the chart and write them on their whiteboard.

○ Ex. 2 times 6, 1 times 12, 4 times 3, 3 times 4. Etc.

○ Once they have finished writing all the factors have them say the product for those factors.

○ Repeat at least 3 times

Hand the student the worksheet in Step 3 for independent practice.

Step 3: Complete the worksheet attached below.

Step 4: Review. Start the next lesson with the game or activity attached below for review so the student can demonstrate

understanding of this lesson before moving forward.
