NUMB3RS - Season 3 - "Democracy" - I Never Metadata I Didn't Like
In "Democracy", Charlie investigates the death of a friend. He finds columns of numbers on her computer, and because they are not labeled, he does not know what they mean. He explains, "Numbers tend to come in groups 'it's called metadata' information about data". In this activity, students will ...https://education.ti.com/en/activity/detail/numb3rs--season-3--democracy--i-never-metadata-i-didnt-like
Picturing Percents
Students represent percents on a 10 X 10 grid. They use the grid and the calculator to generate patterns that lead to methods for calculating percentages.https://education.ti.com/en/activity/detail/picturing-percents
Remainder Rules
Students use calculators, whole-number division, multiplication, addition, and subtraction to generate mathematical expressions that describe the relationships between dividends, divisors, quotients, and remainders.https://education.ti.com/en/activity/detail/remainder-rules
The Number of Years
Students' will chart the various ages of the other students in their classroom then the students will multiply the ages by 2 using a lower level calculator, they will then add up the total ages using the same calculator - they can now divide the class into two groups (boys/girls) and see which gr...https://education.ti.com/en/activity/detail/the-number-of-years
