Andrew decorated 20 biscuits to take to a party. He lined them up and put icing on every second biscuit and different decorations on other biscuits. How many biscuits weren't decorated?
Find the squares that Froggie skips onto to get to the pumpkin
patch. She starts on 3 and finishes on 30, but she lands only on a
square that has a number 3 more than the square she skips from.
Kimie and Sebastian were making sticks from interlocking cubes and
lining them up. Can they make their lines the same length? Can they
make any other lines?
Skip counting or counting by the same number each time is ways
to describe constant counting. This is what happens when you recite
the multiplication tables. Work partners Joanne and Holly, and Steve and Matt from Moorefield Junior School,
found that to reach 24 they could count by skipping 1s, 2s, 3s, 4s,
6s, 8s, 12s or 24s to reach 24, the target number. 24 is an answer
in each one of those multiplication tables.
David, who is
studying at De Aston School, gives us this example:
24 = 1 x 24
24 = 2 x 12
24 = 3 x 8
24 = 4 x 6
Several people did not mention counting by one or by two;
perhaps they thought that was too obvious. Others found some of the
different ways to skip count to reach 24 but did not list all of
the possible ways.
