E kiia ana ko Scratch/Dig he koha whakapaipai ka kitea i runga i te karaihe i te wa e tukatuka hohonu ana. Ko te iti o te ōwehenga, ka kaha ake te paerewa. Ko te tono motuhake ka whakatau i te taumata kounga me nga tikanga whakamatautau e tika ana. Ina koa, ka tautuhi i te mana o te porihi, te waahi o te karawarawa me te keri.
Nga karawarawa– Ko te rakuraku ka kiia he "haehae" rarangi o te mata o te karaihe. E tohu ana te karaehe rakuraku ki te whanui rakuraku me te tirotiro ma te tirohanga tirohanga. Ko te papanga karaihe, te paninga me te ahuatanga rama ka pa ki te ahua o te pakaru i etahi tohu.
Ka keri– Ko te keri he rua, he rua iti ranei kei te mata o te karaihe. Ko te tohu keri e tohu ana i te rahi tonu o te keri i roto i nga haurau o te mirimita me te tirotirohia e te diameter. Ko te diameter o te keri he rereke te ahua he ½ x (Te roa + te whanui).
