What we like about this task

Mathematically:

  • Addresses standards:  K.CC.B, K.NBT.A.1, and MP.2
  • Connects counting, cardinality, and linear ordering of numbers (K.CC.B)
  • Builds meaning for numbers 11-19 as ten ones and some more ones (K.NBT.A.1)
  • Relates concrete quantities and abstract symbols (MP.2)

In the classroom:

  • Uses concrete representation to make the mathematics explicit
  • Allows for group or individual work
  • Can lead into related discussions (such as one more/one less)
