Should Programming Be Mandatory?

A conversation about programming and children recently unfolded on Twitter. One comment that stood out for me was the idea that programming should not be mandatory, that children should have the option to learn this skill. I disagree. I think programming has earned a place alongside reading, writing, math, science, and social studies.

In fact, introduction to programming concepts should begin as early as kindergarten. My colleagues and I have been teaching mathematics through… Continue

Pecha Kucha

My Algebra I and Geometry classes are creating a Pecha Kucha with photos taken around the school (in some cases they used photos from the internet). They are using a variety of methods for presentation.. some have chosen to present as a power point with personal narration, some are recording over the slides for an automated presentation, and some are creating movies with narration. They are working in groups of 1, 2, or 3. I will try to post the best next week (our last week in school - yea!)

Misconception in Math

1.A three digit number is always greater than a two digit number....more stress is on number of digits than the value of a number

2.When we multiply two numbers product is always greater...What about when multipling fractions or decimal numbers.
