Hint One:-What manipulatives can

you use to find the answer to this problem?

-How would you set this problem up?

Hint Two:-What can you use from

the previous question to find this answer?

-How could you us a table to do this problem? T-Chart??

Melting SnowmanOn Monday the temperature was 30 degree F and it snowed all day. You had a snow day off from school and built a snowman with friends. The snowman will melt when the temperature reaches 50 degrees F. If the temperature rises four degrees every day, starting on Tuesday, what day will the snowman be melted?

Hint

• What can you find out to help get this problem started?

• Could you use a chart for this problem?• How about a number line?
