- Rounding off numbers.
- Estimating answers to calculations.
Outcomes
In this lesson you will learn about:
This YouTube video explores the concepts of approximations and estimations.
Concept of density. This YouTube video will provide information about the concept of density. It’s great to use as an introduction to the topic or as a way to summarise the topic.
Outcomes:
This video will look at rotation. Rotation involves turning a shape around a set point.
This online lesson explains what rotations are.
This online activity is a math game on rounding numbers.
This is an online activity that provides you with various exercises on rounding whole numbers.
Students learn about two-axis rotations, and specifically how to rotate objects both physically and mentally about two axes. A two-axis rotation is a rotation of an object about a combination of x, y or z-axes, as opposed to a single-axis rotation, which is about a single x, y or z-axis. Students practice drawing two-axis rotations through an exercise using simple cube blocks to create shapes, and then drawing on triangle-dot paper the shapes from various x-, y- and z-axis rotation perspectives.
