LEERDERS AFDELING

Inhoud

Aktiwiteit: om uitsetwaardes vir gegewe insetwaardes te bepaal lu 2.3]

1. Hieronder is ‘n voorbeeld van ‘n “vloeidiagram”. Die getalle aan die linkerkant noem ons die “insetwaardes” en die antwoorde wat jy moet verskaf, die “uitsetwaardes”. Kyk of jy die vloeidiagram sonder ’n sakrekenaar kan voltooi.

2. Kontroleer nou jou antwoorde met ’n sakrekenaar.

3. Hoe kon jy die antwoorde bereken SONDER om eers 19 en dan 21 af te trek?

KOPKRAPPER!

Opeenvolgende getalle is getalle wat direk op mekaar volg wanneer jy tel, bv. 22 en 23. Kan jy vasstel watter opeenvolgende getalle die volgende getallesinne waar sal maak?
