Learning goals
- We are learning to read, write, name and order two-digit numbers to at least 120 using concrete materials, hundred charts and number lines.
- We are learning to model problems involving addition and subtraction, including simple whole-dollar money problems, in practical role-play situations.
- We are learning to solve problems involving modelling addition, subtraction, equal sharing and grouping, using different strategies.
- We are learning to read, write, model and represent numbers to 100 in different ways and on number lines.
- We are learning to show that two- and three-digit numbers can be partitioned and re-named in different ways, such as partitioning three-digit numbers into hundreds, tens and ones.
- We are learning to count collections to 1000 using place value groupings.
