Problem Solving The Dog, the Goose and the Bag of Corn The farmer takes the goose across and leaves the dog with the corn. The farmer then goes back across the stream and gets the corn. He takes the goose back across with him because he cannot leave it with the corn. He then gets the dog and takes it across leaving it on the other side with the corn. He then goes back across once again, gets the goose and returns to the other side of the stream with all safely across and not eaten!

Problem Solving “Let’s Make Some CENTS of This!”
Sam has 50 cents in nickels and dimes. How many of each type of coin could he have?
Organize your information and present the possible answers in your Math Journal.
After you list all the possible ways he could have 50 cents in nickels and dimes, what if I said that he has exactly 7 coins? What would the answer be now?

Problem Solving:

Problem Solving Let’s Make Some Cents of This! Sam could have the following coins:
1 dime & 8 nickels
2 dimes & 6 nickels
3 dimes & 4 nickels
4 dimes & 2 nickels
if he has exactly 7 coins he would have 3 dimes and 4 nickels!

“The Pet Problem”
One bright and sunny day, a truck delivered a box of new animals to the pet store. Hannah needed to count the number of animals in the box. When she peeked in, she saw many snakes and tarantulas all mixed up! She carefully counted 18 heads and 64 legs.
How many snakes were in the box and how many tarantulas? Show how you solved this problem by writing down your thinking in your Math Journal.

Problem Solving:

Problem Solving The entire focus of elementary math is to encourage independent problem solving. Most of the process can be written a Math Journal. Here are some suggested questions that students could use as a format when writing in their journal.
1. Did I state the problem or question?
2. Did I write as a mathematician & use appropriate vocabulary.
3. Did I state the strategies I used?
4. Is my reasoning logical?
5. Did I show a picture, graph or table, of the problem?
6. Is my answer reasonable & is it labeled?
7. Did I summarize & justify my answer?
