Revise: In the last task we saw that two-digit numbers are made up of tens and ones. The first digit in a two-digit number represents the total number of tens and the second digit represents the number of ones.

Explain to students that they will be playing a game to build their understanding of tens and ones.

Show students how to play Planting 50 in pairs:

  1. Students take turns rolling a standard 6-sided die and collecting the number of seeds (counters) indicated. They place the seeds in the punnet (ten-frame) under the heading "Ones" on their gameboard.
  2. When a punnet is filled, the student groups the 10 seeds together and places the seeds in a circle under the heading "Tens" on their gameboard.
  3. The first player to collect 50 seeds is the winner.
