  1. Hi Mrs Madden,
    We played this game today and loved it. We are going to add this to our Maths taskboard. The children even thought of ways to make it more challenging. Thanks Mrs Madden! From Room 21

  3. Well done Kikorangi Blue, I like how you have recorded all the number stories to match the towers. Lauchy noticed reversibility. ie 20 - 1 = 19 and 19 + 1 = 20 ; 18 - 3 = 15 and 3 + 15 = 18 ; 12 - 3 = 9 and 3 + 9 = 12 ; 13 - 5 = 8 and 8 + 5 = 13
