This problem solving activity has a number focus.
Select a number less than 20.
Skip count with it to 1000.
How many numbers can you find that will hit no hundreds through to 1000.
This problem explores the idea that large numbers are made up of smaller numbers. It also helps students form a more accurate idea of the value of a 1000. The students develop their understanding of multiples by skip counting with a calculator, using the repeat function. For example, skip count by sevens by pressing: 7 + = = = etc. The calculator allows the students to work with larger numbers, to look for patterns in the multiples of numbers, and apply this knowledge to solving problems.
