Go Fish:
Cut out fish shapes and number or whatever. Attach a
paper clip or twist tie to the mouth. Tie a magnet onto a
piece of string to use as a fishing pole. Extension: Make
red, black, white, blue and newspaper fish. Put them on some
newspaper spread on the floor; give them 10 seconds to catch
as many fish as they can with their hands. Which ones are
caught most often? Least often? Why do you think that is? 

Sink the Boat:
Students can practice estimation by constructing foil
boats and using pennies to see how many the boat will hold.
Salt of the Sea:
Using 2 clear cups, fill each ¾ with water. In one
cup, stir in 3 T. of salt. Label the cups A and B. Ask
students to predict what will happen when you place an egg in
cup A. Place the egg in carefully. Next ask the students
what will happen when you put it in cup B. Ask why? Salt
adds density to the water so objects float.
