How Many Are Hiding?

September 25, 2016

Materials:

  • 10 or more snap cubes / objects per player
  • a cup for each player

Task Instruction

  • In this activity each child has the same number of cubes and a cup
  • They take turns hiding some of their cubes in the cup and showing the leftovers
  • Other children work out the answer to the question “How many are hiding,” and say the full number combination

Example: I have 10 cubes and I decide to hide 4 in my cup. My group can see that I only have 6 cubes. Students should be able to say that I’m hiding 4 cubes and that 6 and 4 make 10.
