Investigate, with and without digital technologies, angles on a straight line, angles at a point and vertically opposite angles. Use results to find unknown angles (ACMMG141)
Vertically opposite angles
Explore angles formed by a transversal line intersecting parallel lines. Look at illustrations showing pairs of angles: vertically opposite, corresponding and alternate angles. Name pairs of angles to score points and help a monkey drive to the supermarket to buy food.
Use these resources to develop your students' skills in measuring and constructing different angles, classifying angles in relation to a right angle and understanding of properties of angles. Students apply their understanding of how to use a protractor through fun and familiar contexts.
This sequence of four lessons focuses on working with solids and their nets. The lessons provide opportunities for students to work flexibly as they construct simple prisms and pyramids from nets they have created. Students record their mathematical thinking as they work through iterations to refine a box that has the least ...
This iPad app is a digital 180-degree protractor. Angles can read from the right or left of the perpendicular, and acute and obtuse angles are shown in different colours. Angles can be set by moving the pointer or using the keyboard to enter the required degree of angle. The angle can also be locked when taking readings.
Lost your protractor? Well, find out how to make an 'angle-a-tron'. This might just be the coolest mathematical tool you've ever used. Measure all sorts of angles. It's easy with an angle-a-tron!
These seven learning activities, which focus on 'games, simulations and modelling' using a variety of tools (software) and devices (hardware), illustrate the ways in which content, pedagogy and technology can be successfully and effectively integrated in order to promote learning. In the activities, teachers use games, ...
