Learning Outcomes
Students will:
- estimate the size of numbers to
the nearest 10 or 100.
Activity
- Have the children use a length of
string to make a number line to 100. The length
of string should reach across the classroom. Hang
cards, decorated with groups of krill and with
the appropriate numbers, at the multiples of ten
along the line. Using a cutout of a whale, place
it at various places along the number line and
ask the children where the closest group of krill
is located.
