  1. Odštevam dvomestna števila do 100

  2. Preriši spodnjo sliko v zvezek in zapiši račun. Janez je imel 67 frnikol. 32 jih je izgubil. Koliko frnikol še ima?

  3. 67 – 22 = 47 – 2 = 45 2 20 Odštevanec ( v našem primeru je to število 22) razdeliš na desetice in enice: 20 in 2. Nato od zmanjševanca odšteješ desetico ( 67- 20 =47). Temu številu odštejemo še enice ( 47 – 2 ) in dobimo rezultat 45, ki ga imenujemo razlika.

  4. Oglej si spodnjo sliko, zapiši račun in ga izračunaj. 88 – 56 = 38 – 6 = 32

  5. Spodnje račune prepiši v zvezek in jih izračunaj. Rešene račune mi pošlji na moj elektronski naslov  .

  6. Spodnje naloge prepiši v zvezek in jih reši. 1. 2. Rešene naloge mi posreduj, da jih lahko pregledam.
