In this activity, students develop an understanding of the relationship between a number and its square root. They will first recognize perfect squares and order them from least to greatest with other numbers. Then students will estimate the square root of a number using perfect squares.

Students explore numbers and number representations for fractions, decimals, and percents.

This activity gives students an opportunity to see where large and small numbers are used and how scientific notation offers a convenient method of writing such numbers.

In this activity, students use Venn Diagrams to classify numbers. They will first classify multiples of 3, 5, and 6, deciding where to place the least common multiple. Then, students will use the TI-84 Plus C Silver Edition™ integer division and remainder features to help them classify factors of three different numbers.
