Mental math is an important part of today’s math curriculum, especially those that are implementing the Common Core. Even if this is not the way that you learned math when you were in school, I will promise you that it is extremely effective and REALLY makes sense once you get started with it.
Rather than writing everything out here, I am going to share a couple of videos that I created last year. They will give you a quick overview of some of the most effective strategies as well as a recommended order of teaching.
The first video explains Mental Math addition strategies:
This video explains Mental Math subtraction strategies:
I hope that these videos are useful to your mental math instruction!
to help end world hunger by providing rice to hungry people for free.
How does it work? Players answer quiz questions, and for every correct answer the World Food Programme provides ten grains of rice to hungry people all over the world. Free Rice has several subjects from which to choose including English vocabulary, world geography, math, science, art and foreign languages.

Another thing I love about making movies in class [...]
During my first year of teaching, I learned quickly my “area of expertise” wouldn’t be the only area I teach. Nope, college professors don’t tell you about other subjects you cover. Divorce. Death. Tampons. Abuse. Break-ups. Adoption. STDs. Foster Care. Broken hearts. Broken immune systems. Insecurities. Addictions. Evictions. Abandonment. However, there is a safe place students arrive daily, a place of hope, a place of comfort, a place [...]
As we approach the end of the school year, it might be a perfect time to give students space for some self evaluation. The following is a simple lesson idea for middle or high school students which asks them to look back over their school year and evaluate changes in themselves. It’s not a bad [...]
Interruptions from young children can become a major distraction in the classroom. Check out the following two ideas from teachers of elementary students, which I saw this week on Teaching Channel. Both are brilliantly simple ways to help young students not interrupt the teacher when he/she is working with a small group on a certain [...]
One of the most highly searched character-related education topics is how to teach kids respect, according to google searches. It’s the character trait teachers scour the internet to find ideas on how to teach most often. And it’s not difficult to see why– respect has its fingers in almost all classroom management issues. Respect can [...]
Have you seen this video? It’s been making the rounds on the interwebz for awhile and recently gained attention again when a high profile video-curating site shared it. Currently it has over 70 million views. Take a look–it’s only 45 seconds: What thoughts floated through your mind as you listened to this child sing? Maybe [...]
