Comparing Notes: a Mathematical Exploration of the Piano

It is hard to determine whether there is a relationship with the categorical data, because the numbers are so different. Working with a familiar two-way table on super powers, the class determines relative frequencies for each...

The original drawing is eight units — how big is the scale drawing? Classmates determine the scale percent between a scale drawing and an object to calculate the length of a portion of the object. They use the percent equation to find...

Designed as an assessment of understanding, this one-page worksheet asks musicians to demonstrate their understanding of scales by drawing C, G, and F Major scales on the provided staffs. 

How do you put something as large as the universe in perspective? Use a series of scale experiments. Classmates collaborate around four experiments to examine the scale of the earth-moon system, our solar system, the Milky Way galaxy,...

Calculate the areas of scale drawings until a more efficient method emerges. Pupils find the relationship between the scale factor of a scale drawing and the scale of the areas. They determine the scale of the areas is the square of the...

It is all relative, or is it all conditional? Using an exploration method, the class determines whether there is an association between gender and superpower wish through the use of calculating conditional relative frequencies. The...

The finer points of telling the difference between cumulative and frequency histograms are laid out with clear examples for how to get from one to the other. From defining vocabulary through converting charted data to histogram form,...

What's the association? Pupils watch a presentation on creating a two-way frequency table. Learners find out how to calculate relative frequencies within the table to determine whether there is an association between the two categories....

Investigate the use of ratios in scale drawings. Learners scale objects up or down using ratios then find the actual size of something using ratios. They apply their knowledge of ratios as they make their own telescopes in science...

Try your hand at scale models. Scholars create a scale model of an object using a scale factor of their choice. As part of the project, they give presentations on their processes and calculations. This is the last installment of the...
