Please note: It is important for teachers to know that our sequential units are intended as a significant support for planning, not as a strict or prescriptive approach. For example, we aim for teachers to continue to use other high-impact lessons that have worked well for them in the past, and other excellent resources. Our goal is to create the best menu of rich learning experiences and collection of open-ended lessons for each concept, however, we want teachers to selectively choose the point-of-need sessions for their class that most powerfully speak to their passion as a teacher and motivate more use of hands-on maths. It is not intended for teams to use every lesson within a unit. Instead, we recommend that teachers selectively choose lessons from the sequential units that best match their current learning intention and students' next learning goals, as well as students' interests, and sessions that the teacher feels confident in being able to deliver.
