Your family is going on a road trip from Georgia to California. It takes you 8 hours to cross over each state. How long will it take you to get to California if you cross over 7 states?

Every four hours your family stops for 30 minutes of rest, food, and gas. How much time will be spent on stops?

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.
