Activity Overview
Students explore a range of number patterns using division and remainder and the reverse, multiplication and addition. The activity relates to the division algorithm and references terms such as quotient, dividend and remainder.

Vocabulary
ivisor, dividend, quotient, remainder factor, composite
About the Lesson
Consider a number that has been divided by 3 and results in a remainder of 2. Another number is chosen, divided by 3 and again the remainder 2. The pattern continues as the next number is selected, divided by 3 and again the remainder is 2. What are the numbers and what is the pattern? Students use the unique ‘integer division’ feature of the TI-15 to display the quotient and remainder and relate this to the division algorithm. The algorithm states that each integer can be written as the product of two other integers plus the sum of a third.
