Andy and his friend Sam were walking along the road together. Andy had a big bag of marbles. Unfortunately the bottom of the bag split and all the marbles spilled out. Poor Andy!

• Andy and Sam picked up all they could but half (12) of the marbles that remained nearby were picked up by other children who ran off with them.
• Andy counted all the marbles he and Sam had rescued.
