This resource contains 24 task cards that focus on doubling, halving and multiplying by two. Each card has four panels, three of the panels represent the same number and one does not - it doesn’t match. Students need to figure out which of the panels doesn’t match and show which one it is by placing a peg on top it. This activity will assist in the practising and reinforcing of doubling, halving and multiplying skills. The task cards can be printed on thick card and cut up into individual task cards. This activity pairs well with our Double or Halve Board Game.
