How can you represent the number of animal cards Liz could have?
Liz has 9 animal cards
They are elephant cards and tiger cards
Liz could have 4 elephant cards and 5 tiger cards
The equation is 4 + 5 = 9 or
3 elephant cards and 6 tiger cards
The equation is 3 + 6 = 9
Therefore, these are different combinations of 9.
Read this problem aloud: Liz has 9 animal cards. They are elephant cards and tiger cards. How many of each animal card could she have? Children should share different combinations of numbers that add to 9.
Raul and Jon have 14 books altogether. How many books could each boy have?
A. How can you show the problem and a possible answer?
B. How can you use words to explain your answer?
C. How can you write an equation to prove your answer is correct?
Raul and Jon have 14 books altogether
There are different combinations for 14
I made 2 combinations
The equations are 10 + 4 = 14 and 7 + 7 = 14
So, Raul and Jon could have 10 and 4 books each or
7 books each.
Turn and Talk What could be another answer for this problem?
Jill has 17 pieces of fruit. She has pears and kiwis. How many of each could she have?
B. Write an equation to prove your answer is correct.
Jill has 17 pieces of fruit
She has pears and kiwis
She could have 10 pears and 7 kiwis
The equation is 10 + 7 =17.
Turn and Talk How would your model change if Jill had 1 more pear?
If Jill had i more pear then she could have 11 pears and 6 kiwis
The equation is 11 + 6 = 17.
