Playful Math for Middle & High School
As our children (and their parents!) play around with mathematical ideas and the relationships between them, we develop deep understanding that is strong enough to support future learning.
Putting Bill Gates in Proportion: "The average household income in the United States is $60,000/year. And a man’s annual income is $56 billion. Is there a way to figure out what this man’s value of $1mil is, compared to the person who earns $60,000/year?...
Teaching Quadratics using M&M Catapults! "When the kids are consistent and do their calculations correctly, they will hit the center of the target with ease. It's one of the all too rare opportunities that students get to see that the math they did directly affected something in real life..."
"Different perspective on graphing. Had each student solve 2x-3 = ( ). Gave each students a different number to replace the (). The students solved and graphed their solution on a separate number line. We then built a cartesian graph 2x-3=y by stacking the graphs in order. Pretty awesome and the students loved it!"
Hands-on Surface Area of Prisms: "I think the hands-on experience of finding the surface area of multiple rectangular prisms helped them to understand the process of needing to find the area of each face and then add them together to get the total surface area..."
"Over the last decades, the Multiplication Tower idea has been appearing in many different projects... Kids and their grown-ups build multiplication towers using many kinds of materials: wooden blocks, LEGO bricks, software and 3D printing, and beads."
