Year 1
Unit 1: Adding & subtracting by reversing
The silver coins
-
Efficient, essential only instruction, highly aligned to the learning intention and practice material to come. Progression to the pictorial and abstract. Highly connected to Phase 1 - a further enhancing instruction experience.
Identify the four Australian silver coins by name, value, and the picture on each. Compare coins by value. Combine silver coins to make small amounts.
-
This allows for understanding of the smallest content knowledge to be developed. Often these are overlooked in the explicit instruction, contributing to cognitive overload and confusion.
Tier 1: Start here. Most students will still get a lot of value out of these activities.
Tier 2: Essential and may need longer here than Tier 1.
Tier 3: Highly relevant intervention instruction, and for those with SLDs requiring extensive chunking and more time to acquire.
-
Progress through rehearsal through practice replicating phase 1 and 2, then progressing to the generalising stage and fdor students who are competant they will need challenge problems.
