In this lesson, Ms Kirszman teaches you how to play Minute To Win It, and she explores how we can quantify collections without needing to count but by looking and thinking instead.

In this lesson, Ms Kirszman demonstrates how to measure using 10 as a unit to iterate, rather than using a smaller unit. You will also explore how renaming, using place value parts, can help you when working with numbers.

In this lesson, Ms Kirszman tells you about a very robust and interesting debate that took place with her class when the students needed to find some missing information on a number line.

In this lesson, you will explore the renaming of numbers in their place value parts as well as standard and non-standard partitioning. You'll also see how tables can be useful tools for mathematicians when solving problems.

In this lesson, you will continue to partition numbers in standard and non-standard ways. You'll also explore how the same problem can be solved in many ways.
