It’s Wednesday – here are some problems to solve

Soon it will be Jayce’s birthday.  He is hanging balloons fro decorations.  He has 4 bags of yellow balloons and 5 bags of blue balloons.  Each bag has ten balloons in it.  How many balloon does Jayce have altogether?

Jayce and his friends played games with the balloons.  At the end of the party half of them had been popped.  How many balloons were left?

One of the activities at the party was making individual puzzles.  Jayce and his friends drew pictures on cardboard.  They cut them into 12 rows.  They cut each row into 12 pieces.  How many pieces were there altogether in each puzzle?
