La mamma di Camilla è una gran cuoca e oggi voglia di cucinare una crostata di frutta. Sfortunatamente si rende che le manca l’ingrediente principale: la frutta. La mamma chiede a Camilla di andare al mercato e di fare un a piccola spesa per lei. Camilla dovrà comprare: 4 fragole, 3 mele, poi 2 arance per ogni mela e 3 ciliegie per ogni arancia. Quando Camilla torna con la frutta, la mamma le chiede: “quanti frutti hai preso in totale? Aiuta Camilla a rispondere alla mamma.
4 fragole:




3 mele :



2 arance per ogni mela :









3 ciliegie per ogni arancia:
























la risoluzione del problema è molto semplice, o si conta ogni singola frutta oppure si compiono operazioni più semplici :
4 + 3 =7
2 x 3 =6
6 x3 = 18
7 +6 +18 = 31
