  1. Kautehia te katoa mai i te kotahi 1,2,3,4,5,6,7,8.....9,10,11,12,13. Kautehia ake mai i tetahi tau 8.....9,10,11,12,13. 8 + 5 = Wawahia tau: 8 + 2 + 3 = 10 + 3 = 13. 5 + 3 + 5 = 10 + 3 = 13 8 + 8 - 3 = 16 – 3 = 13

  2. Kautehia ake mai i tetahi tau 29.....30,31,32,33,34,35,36 29 + 7 = Wawahia tau: 29 + 1 + 6 = 30 + 6 = 36 20 + 9 + 7 = 20 + 16 = 36 Tau mama me te tikanga paremata 29 + 10 – 3 = 39 – 3 = 36

  3. Kautehia iho mai i te tau nui (kia tupato – kaua e aro ki 37!) 36,35,34,33,32,31,30,29,28 Huri koaro 9 +  = 37 9 + 1 + 20 + 7 = 37  1+20+7=28 37 au rare, a, ka kaingia kia 9 e koe, e hia au rare e toe ana? Wawahia tau: 37 – 7 – 2 = 28 Tau mama me te tikanga paremata 37 – 10 + 1 = 28

  4. Huri koaro 26 +  = 53 26 + 4 +20 +3 = 53  4+20+3=27 53 ngā tāngata kei runga i tētahi pahi. Ko 26 o rātou e heke ana. Tokohia ngā tāngata i runga tonu i te pahi? Wawahia tau: 53 – 3 – 20 - 3 = 27 53 - 26= 25 + 25 + 3 – 26 = 25 +2 = 27 26 + 26 + 1 = 53  26 + 1 = 27 Tau mama me te tikanga paremata 53 – 30 + 4 = 27

  5. Wawahi uara tu 300 90 + 70 = 160  300 + 160+13 = 473 4 + 9 = 13 394 ngā pukapuka a Hanira. I hokona mai 79 nga pukapuka ano e ia. E hia āna pukapuka inaianei? Wawahia tau: 394 + 6 + 73 = 400 + 73 = 473 Tau mama me te tikanga paremata 394 + 80 -1 = 474 – 1 = 473

  6. Huri koaro 2.89 + 0.11 + 2 + 0.3 = 5.3  0.11+2+0.3=2.41 5.3 m te roa o tētahi rākau. Ka tapahia atu kia 2.89 m. E hia te roa rakau e toe ana? Wawahia tau: 5.3 -0.3 - 2 – 0.59 = 2.41 Tau mama me te tikanga paremata 5.3 – 3 +0.11 = 2.3 + 0.11 = 2.41

  7. I hokona e Hare rāua ko Teri e 2 ngā parehe. I kaingia ¾ o tētahi e Hare. I kaingia hoki 7/8 o tētahi atu e Teri. He pēhea nei te rahi o ngā toenga? Hautau orite 16 nga 1/8 i ro nga mea e rua. 6 + 7 nga 1/8 i kaingia. No reira 3/8 e toe ana Hautau orite ¾ = 6/8  2/8 te toenga 7/8  1/8 te toenga  2/8 + 1/8 = 3/8
