Mathematics – Stage 1 – Year B – Unit 40
This two-week unit develops student knowledge, understanding and skills to solve problems using critical and strategic thinking.
Mathematics K-10 Syllabus © 2022 NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales.
Students are provided opportunities to:
- investigate time and duration problems using calendars and clocks
- solve addition and subtraction problems using objects, diagrams, images and models
- record answers to multiplication and division problems (including those with remainders) using drawings, words and numerals.
