Concept Learning & Skill Development
Number & Computation A
Years 2  6(8)
Based on an array model of multiplication students experience how to know the answers to their times tables. Uncover Counting is used to reveal the 6, 7, 8, 9 &10 times tables.
Number & Computation B
Years 2  6(8)
Students choose their own time limit to complete 20 Times Tables Torture questions. Using array images they correct their work and find two ways of knowing each table.
Number & Computation C
Years 2  8
Students build Rod Mats and explore relationships between rows of rods the same size. Natural language drives the investigation of fraction equivalence and operations.
