FACE THE NUMBERS

• If the monkey face stands for 5, how can you

figure out what number the dog face stands

for? (In Equation B, replace the monkey face with 5.

The dog face will then equal 3. 3 + 5 = 8)

• Look at question 5. How can you figure out the

sum? (Replace each face with its number and then

add: 3 + 3 = 6.)

Work together as a class to answer the questions

in “Solve the Problem: Face the Numbers.”

Math Chat With the Transparency

Display the “Make the Case: Face the Numbers”

transparency on the overhead. Before children

can decide which character is “wearing smarty

pants,” they need to figure out the answer to the

problem. Encourage children to work in pairs to

solve the problem. Then bring the class together

for another whole-class discussion. Ask:

• Who has the right answer? (Carl Cargo)


• How did you figure it out? (Equation A shows

that a duck face + 3 = 9, so a duck face is 6. In

equation B, replace the duck face with 6. Then, the

cat face + 6 = 10, and the cat face is 4.)

• How do you think Shorty Trunks got the

answer that the duck face stands for 6 and the

cat face stands for 5? (He got the number for the

duck, but he might have mistakenly thought that

each face in Equation B stands for the same number.

So, he took half of 10 and got 5.)

• How do you think Levi Sam got the answer that

the duck face stands for 3 and the cat face

stands for 7? (He may have made a mistake solving

for the value of the duck face in Equation A, think-

ing that it was 3. Or, he might have just used the

number 3 in Equation A for the duck face. He then

replaced the duck face with 3 in Equation B and found the cat face to be 7.)
