Data
1.) Each student will have a copy of a hundreds
chart (a chart ten rows wide by ten columns numbered 1 through 100). They
will color in all numbers divisible by 2 in one color and all numbers divisible
by 3 in a different color. They will repeat this process for 5, 7, and
9. When the chart is colored, they will see different patterns, as well
as some numbers colored many times. The numbers that remain uncolored are
the prime numbers (up to 100). The chart is a handy reference for students
as well as reinforcing the divisibility rules.
2.) Students are given any number of color tiles
up to 100. They will arrange them in as many different rectangles as possible.
This will help them to see that numbers can be factored in different ways.
They can record their rectangles on graph paper, and all the rectangles
for a number can be glued to a sheet of construction paper. Over a period
of days, all numbers from 1 to 100 can be investigated and displayed in
the room for reference and discussion. They will recognize that numbers
with only one kind of rectangle are prime numbers.

Data
1.) Students will identify which of the following
numbers are prime and explain why: 45, 67, 93, 24, 87, 29.
2.) Students will list or show the different
arrangements for the following: If there are 100 ants marching along, how
many different ways could they arrange themselves in rows, with none left
over?
