In this course, students work with numbers within 20; use addition and subtraction with linear measurement; understand place value to read, write and compare numbers; add and subtract within 1000; use place value with money, linear measurement and time; collect and analyze data; and build the foundation for multiplication and division. 

In this book you will work like a mathematician to find the answers to questions 
like these:
• What are negative numbers and when are they used?
• How can you quickly find out if 1435 is in the 25 times table?
• Which is bigger: half a cake or 50 percent of a cake?
• What might you be doing at the time 23:30?
• What shape is a cone?
• What is a dot plot?
•  What comes between the points 
north, east, south and west on a 
compass?
Talk about the mathematics as you explore 
and learn. This helps you to reflect on what 
you did and refine the mathematical ideas 
to develop a more effective approach or 
solution.
You will be able to practise new skills, 
check how you are doing and also 
challenge yourself to find out more. You will 
be able to make connections between what 
seem to be different areas of mathematics.
We hope you enjoy thinking and working like a
