Description

This is a GREAT lab for students to discover the value of patterns in our wonderful world of mathematics!

* In the lesson, students DO discover a relationship between fractions and decimals beginning with NINETEEN FRACTIONS THAT STUDENTS ARE REQUIRED TO DIVIDE THE NUMERATOR BY THE DENOMINATOR ON EACH.

* Students learn the meaning of the terms "terminating" and "repeating" relative to decimals.

* Students learn how and when it is appropriate to use the bar above repeating decimals.

* Using prime factors, students uncover a surprising and practical pattern found in all terminating decimals.

* At the conclusion of the lesson, students have an opportunity to reflect on what they have learned.

As a teacher, I adore presenting this activity to my students!

Please share my enthusiasm for this Math Lab!!!

Happy teaching!

CCSS8.NS.A.1

Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number.

CCSS8.NS.A.2

Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., π²). For example, by truncating the decimal expansion of √2, show that √2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations.
