I’m finishing up my plans for the new Charlotte Mason’s Living Math Kickstarter project and pledge levels, which launches early in March.
And I’d really appreciate your help.
Could you please take a few minutes to look over the project page and give me some feedback?
Having new eyes on the page helps make sure everything makes sense.
Coming Soon! In March, I’ll be launching my newest book, Charlotte Mason’s Living Math: How to Apply the Principles of Education to Help Children Develop Mathematical Reasoning.
And the Kickstarter prelaunch page is now live. That means you can sign up to get an email from Kickstarter as soon as the campaign launches:
(If you back the campaign on launch day, that encourages the Kickstarter folks to share it with more people.)
The farther we go in math, the more division disappears. It ceases to exist as a separate concept.
Instead, we learn to see division as:
Each of these perspectives offers us a new way to think about and make sense of our calculations.
The methods in last week’s Advanced Multiplication post only work for certain numbers, but we have another, more powerful multiplication tool: We can always use a ratio table to make sense of any multiplication.
Ratios are the beginning of proportional thinking. We can systematically alter the numbers in a ratio to reach any quantity required by our problem.
Students begin working with ratios in story problems that help them visualize and make sense of a proportional relationship.
