Preparing for Learning
Prior to beginning the unit, develop a number display in the classroom. Display posters, word wall vocabulary and learning goals that the students will engage with throughout the unit to stimulate their learning. For examples of such resources, browse the Place Value category on the Teach Starter website.
There are many concepts to address when introducing 3-digit place value to younger students. The lessons in this unit cover a range of these concepts, many of which have varying degrees of complexity. Teachers are encouraged to select lessons from the unit that best suit the learning needs of their students, or to adapt lessons accordingly.
Some of the resources which accompany this unit plan will need to be prepared prior to teaching. For this reason, it is advised that teachers browse through all lessons before starting the unit.
