This two-week unit develops student knowledge and understanding that skills of collections of 10 are really useful. Students are provided opportunities to:
represent numbers in a variety of ways
reason about the way numbers can be combined and separated
use positional language both in a physical world context and in more abstract contexts
compare the weight of different materials by hefting
understand time in everyday contexts and tell time on analog and digital clocks
explain their thinking so it makes sense to others.
Before engaging in these teaching and learning activities, students would benefit from prior experience with:
using language to communicate thinking about quantities to describe features of objects and collections, and to explain mathematical ideas
opportunities to demonstrate an increasing understanding of symbol systems, for example, letters, numbers, spatial sense and measurement
noticing and predicting the patterns of regular routines and the passing of time
contributing constructively to mathematical discussions and arguments.
