Get the most out of this tool
This page helps you find the resources. The books help you decide what to do with them.
The Topics page hands you Interactive Tools, Super 8s, Shedloads, Open Middle problems and more for any topic on the curriculum. What it can’t do is the rest of the work: choosing which resource type fits the moment, getting students to do the practice properly when they’re sitting in front of a worksheet, and pushing all students beyond fluency into the kind of thinking real mathematicians do. That’s what these two books in the Tips for Teachers guide to… series are for.
Tips for Teachers guide to…
Independent Practice
Students often take a cognitive break the moment they’re asked to work independently. This book covers task choice, instructions students actually listen to, the crucial first 30 seconds, effective circulation, and going through the answers without losing the room.
